Financing the investments to provide water on a long term basisat a reasonable price for the population.How to get the maximum number of efcient infrastructuresfrom the money allocated?We need to achieve our objectives at the lowest cost.

Schneider Electric has solutions to reduce both design and operating costs.Methodological tools are necessary or both power and control.

Optimizing costs requires structured design. Schneider Electric oers proven power

and automation architectures to simpliy design. To adopt such architectures,

we provide customers with design, calculation and checking tools.

From design

Design tools enable the power rating to be easily and quickly sized and the electrical

distribution equipment to be chosen. As a consequence, design and installation costs

are reduced and the dierent solutions are easily compared.

Schneider Electric oers a range o variable speed drives with an integrated automation

controller. Using preloaded and user congurable applications, up to ve pumps can be

controlled to ensure a constant water supply.

to operating tools

Collaborative tools allow design, engineering and commissioning, rom the sensor up

to the SCADA (Supervisory Control And Data Acquisition) system. These tools provide

support throughout the projects liecycle, including operation and maintenance,

as well as during extensions and process changes. The savings made by using these

tools are based on proven methodologies and the reuse o predened application

know-how. The unique design and user interace reduce the eort needed or operatorand maintenance training.

Communication

Motor Control Centres (MCC) also reduce design costs. They use the latest

communication technologies (intelligent Motor Control Centres, iMCC) : smaller

components and reduced cabling optimize hardware and labour costs.

10/3610


11/3611

Electrical energy may account for as much as 30% of youroperating costs. 3 aspects of Energy Efciency should beconsidered for a high level of power quality :

>Energy Savings :reduced consumption for all types of operations,> Energy Cost Optimization :reduced costs of the energy used by the different operations,> Availability & Reliability :minimize outage risks through design and strategy, and sustainenergy gains through reliable and efcient equipment operation.

Solutions or energy savings

The latest generation o low-loss

transormers and high perormance

motors allows global eciency to be

improved by up to 5%.

When high power motors are requested

(> 500kW), the use o an Medium Voltage

supply reduces line currents, thus

reducing the Joule losses in transormers,

cables and motors. A Low Voltage supply

may become cost-prohibitive because

equipment sizes get very large, limited or

unavailable, and multiple sets o cables

are needed.>>>

Variable Speed Drives are used to great

advantage in pumping applications.

By adjusting the speed o rotation,

the absorbed electrical power may be

reduced by 50% at 80% o nominal fow.

In water installations, harmonics are mainly

generated by Variable Speed Drives,

Ozone generators and UV lamps, which

should all be careully managed

to avoid resonance, particularly when

Power Factor Correction capacitors are

present.

Increased current demands and nuisance

tripping are the most requent adverse

consequences o harmonics.

Schneider Electric can provide assistance

and solutions or Harmonic management

in compliance with Utility regulations.

Solutions or energy cost optimization

The cost or a given energy consumption

may be reduced in dierent ways.

Power Factor Correction provides several

advantages that add together :

avoids invoicing o reactive energy

by the Utility,

reduces the current demand,

eliminates transormer over-sizing and

allows the ull system capacity to be used.

Power Factor Correction is generally

achieved through the use o capacitor

banks.

Power monitoring devices are used or

2 main reasons :

to know which sectors consume the

most power,

to monitor Energy Eciencyimprovements.

Three types o technologies are available :

stand alone measurement unit,

LV and MV protection relays,

High perormance metering units.

Various resources are used to send data

rom metering and protection devices

installed in the users electrical panels,

via Schneider Electric TransparentReady.

*Sot starters

are available in a wide

range o power ratings,

and are particularly

suitable or water

applications such as

pumping. Multiplexing

is commonly used or

cascading start-ups and

decelerations o multiple

motors.

The ollowing is a list o

the main advantages

this provides :

less mechanical stress

at motor start-up, thus

improving mechanical

reliability,

controlled torque

at motor stopping, thus

avoiding water-hammer

and damage to pipes,

power peak shaving,

thus avoiding penalties, reduced losses

at motor start-up.

Process diagnostics and optimization

Detecting problems as early as possible

avoids process downtime and also

reduces operating costs. Schneider

Electric oers diagnostic tools that are

easy to use and which give ecient

access to relevant inormation, such as

the root cause and process values

needed to x the problem.

At the Supervision Control And Data

Acquisition (SCADA) level, tools such as

Process Analyst are available to create

reports and analyze process data, which

can then be used to optimize the process

in order to reduce electricity consumption.

You are looking

for high availabilitywater treatment . . .


15/3615

The raw material needed to produce drinkingwater may come from different sources(springs, aquifers, rivers, oceans), andappropriate technologies have to be used.The available space and the volume of waterto be treated also determine the technicalchoices. In all cases, the required water qualityhas to be reached and proved in accordancewith regulations and the authorities contracts.

Both the automation system and the electricalnetwork must be studied to provide highperformance and a high level of availability.The solution includes software and hardwarearchitecture with redundancy at all levels:

A high level o availability aects power as well asautomation :

A high level o availability is requested or all parts

o an application identied as being critical, and may include

redundancy or :

power architecture, stand-by generators,

UPS (Uninterruptible Power Supply),

motor control, PLCs (Programmable Logic Controller),

communication and SCADA (Supervision Control

And Data Acquisition).

Power solutions

Dierent Circuit Congurations can be selected, as listed here

in increasing order o power availability :

radial single eeder,

two-pole conguration (secondary selective),

double-ended power supply (primary selective).

The implementation o back-up generators is very common

in water treatment plants where water distribution cannot be

interrupted or periods longer than a ew minutes.

No instantaneous take-over is necessary, as buer tanksare generally present. Automatic transer switches are naturally

associated with generators or rapid take-over and smooth

switch-back to normal supply.

Protection coordination is a key aspect or improving supply

continuity. Two examples are mentioned here :

discrimination between unctional units such that a problem

on a grid doesnt stop biological treatment or instance,

coordination o motor protection and control minimizes

downtime.

Availibility is mainly ocuses on the ollowing three levels

SCADA

On the SCADA side, Schneider Electric oers seamless, integrated and scalable

redundancy. This fexible redundancy can be enlarged to avoid not only network errors,

but also PC hardware errors the result is a highly optimized and available solution.

Network

Ethernet, which has proved itsel over the years as being the reliable industrial

standard, provides the solution or communication architectures requiring high levels

o availability. Communication can easily be adjusted to the required level o availability,

such as redundant media and/or network interaces, sel-healing ber optic rings and

communication backups.

Control

Doubling the PLC gives a highly optimized solution that avoids the negative eects

and process downtime caused by problems at the control level. In the event o an error,

there is an automatic bumpless switchover between the Primary and the Standby PLC -

both are connected by a dedicated high speed Ethernet link. The availability level o the

control system can be increased by duplicating the I/O level, along withthe corresponding sensors and actuators.

Automation components or harsh environments

In water applications, the environment is sometimes polluted and may have negative

impacts on the ageing o the electronic components used. This results in unexpected

downtime and higher maintenance costs. Based on extensive eld experience,

Schneider Electric has developed a special protection process (conormal coating)

to improve service lie in such aggressive chemical and corrosive environments.

a comprehensivepower and controlsolution . . .


19/3619

In a complex process like desalination, integrated solutionsfor power and control are required to reach the expectedperformance level. Based on the size of such applications,a large amount of process information has to be treatedand exchanged between the different parts of the plant.

For such applications we provide dedicated water solution

architectures and tools covering the complete project lifecycle,from design to operation and modernization.

Intelligent Motor Control Centres (iMCC)

Overall perormance or motor control could be increased by using type tested

equipment that oers :

seamless integration into the control system,

prevention o malunction,

type tested equipment, reduction o space, installation time and maintenance,

easy addition or modication o eeders whilst energized.

Collaborative Control System (CCS)

Filtration process applications are based on various dierent components :

controllers,

SCADA systems (Supervisory Control And Data Acquisition),

instrumentation,

drives,

sensors and I/Os.

All these devices must be integrated, congured and optimized during commissioning

and operation.

Schneider Electric collaborative tools cover all the dierent aspects and reduce

integration costs. Proven application knowledge has been integrated into libraries,

thus oering a high level o quality and standardization. The level o standardization

provides consistent user interaces, operating modes and diagnostic capabilities,

thus reducing the amount o training and maintenance needed.

Membrane fltration

Reverse osmosis is the most common

technique used or desalination, and is as

an alternative to distillation. It may also be

used to recycle water to produce drinking

water rom wastewater. Nano ltration

is another example used or instance

to produce drinking water rom surace

water.

Membrane ltration is an up and coming

water treatment technology, or both

industrial and public use. The reduced

space needed or the plant and its ability

to treat all types o raw water are key

drivers.

Membrane technology has meant that

water treatment has changed rom being

a batch process to a continuous process,

which has led to higher perormanceconstraints. High pressure is the key

to membrane ltration. This requires a

high quantity o electrical energy and

the use o high power motors. Electrical

Distribution and Motor Control are thus

a comprehensive part o the process.

Link to the Instrumentation

An instrumentation link based on

standardized protocols enables

signicantly improved mastery o

complex ltration processes. Extensive

process eedback and access to device

parameters increases perormance and

diagnostic capabilities.

Asset management tools with

standardized interaces give access

to devices and provide benets byhaving access to a large range o

parameters and diagnostic inormation.

Hence preventive maintenance can be

used to reduce unexpected downtime.

Availability and operating costs are

greatly improved.

The cost and eciency o membranes

have greatly improved, but membranes

remain ragile. Strict water pre-treatment

is necessary because o the sensitivity to

some pollutants. In addition, membranes

may deteriorate unless they are maintained

under high pressure.

Consequently, power interruptions should

be avoided as much as possible. Power

and control are highly interconnected.

Service Oriented Architectures and open protocols

guarantee an ecient solution.

Schneider Electric oers additional advantages through

a set o innovative solutions or pumping stations :

Increased availability and perormance with multi-drive

solutions or boosting stations

Using several variable speed drives is a way o increasing

system availability. Embedded programmable cards provide

a specic advantage.

Each pump is controlled using a variable speed drive, with

a controller inside the card. The various drives and their cards

are connected via a communication network. Only one pump

(the duty pump) is under variable speed control during normal

operation. The duty is passed rom one pump to anotheron a time basis.

This solution provides additional benets such as smooth

and bumpless control, together with potential cost savings.

Small pumping stations and reservoirs

A cost eective and ready to use solution

- management o two pumps, control by direct-on-line

or sot starters,

- an all-in-one controller, with pre-programmed sotware and

integrated Remote Terminal Unit (RTU) capabilities, providesa solution or pumping stations, recovery stations, reservoirs,

etc.

In drinking water networks, constant distribution pressureis required to reach all oors in urban zones and to overcomephysical barriers in rural zones. Boosting stations are placedalong the network, and both constant availability and real timeadaptation to the users water demands are required.Different technologies are used: from xed to variable speed,from switchboards to stand alone devices, from medium voltageto low voltage. In all cases, perfect integration into the electricaland automation networks is necessary.

A telemetry system is the answer

All links between remote sites are periodic and characterized by exchanges

triggered by cyclical polling rom the central system, upon operator request

or upon the occurrence o an event :

data transmission between remote sites and the central supervisory system

(Scada),

communication protocols (IEC 870, DNP3, Modbus),

media (cable, radio, GSM. Modem, Internet, ),

handling o time stamped events, measurements and buering o data

in case o interrupted links.

Compact RTU all in one (Remote Terminal Unit)

Small applications require optimized solutions. The compact RTU oers:

precongured ready to use applications,

management o up to our pumps,

storage o measurements and events,

integrated RTU communication and is able to be integrated in Telemetry

architectures based on a broad range o standard protocols such as IEC, Modbus

and DNP3.

RTU unctionality integrated in modular PLC (Programmable Logic Controller)

RTU unctions and PLC fexibility orms the basis o the integrated Schneider Electric

oer.

Oering Master and Slave communication opens the door to dierent architectures.

Our solutions are based on reliable and industrially proven hardware, designed or

the harsh environment o wastewater pumping stations. The Modicon PLC range

oers a wide choice to meet the dierent requirements.

SCADA: the central point (Supervision Control And Data Acquisition)

Due to the large distances in pumping networks, seamless communication

integration is the key to monitoring, operating and maintaining such applications.

Our oer includes standard SCADA eatures such as scalability, reporting,

redundancy and diagnostics, as well as specic RTU unctions such as IEC

protocols and the handling o modems, time stamped alarms and data. Data

can be exchanged easily in several well known ormats such as dBase, SQL, Oracle

and several others, or subsequent processing using Oce tools.

Distributed control architectures

To keep up with the fexibility needed in terms o process evolution and the need to

integrate dierent packages such as sludge treatment, distributed control architecture is

the best choice. Its structure o independent unctional units, each equipped with

a modular PLC (Programmable Logic Controller) connected via an industrial network

to the SCADA (Supervision Control And Data Acquisition) system provides a reliable

and fexible solution. Such architectures can easily be modied or extended by adding

new unctional units. Data exchange and synchronisation are based on standard

industrial Ethernet protocols. Our solutions are based on reliable and industrially

proven hardware, designed or the harsh environment o wastewater treatment plants.

Automation islands as an integration platorm

The easy integration o digital and analog signals, motor starters and variable speed

drives is the key to improving and adapting water process applications

in a fexible way. Compatibility with various networks and eld busses allows device

layout standardisation only the communication interace has to be adapted.

This standardisation leads to higher fexibility and cost savings at the engineering

and commissioning stages.

Eective SCADA system to monitor, analyse and optimize the water processTo reach the quality targets set by regulations, the SCADA system has to log and treat

all the relevant process inormation needed to monitor the plant. Schneider Electrics

SCADA system logs data in standard ormats such as dBase, SQL and Oracle.

Process Analyst is the perect tool or analyzing the dierent process data such as

measurements, alarm and digital data sources in one single environment the intuitive

user interace quickly provides the operator with the relevant inormation.

Upgrading o Electrical Distribution and Motor Control

Schneider Electric is able to oer Electrical Distribution equipment retrots as a solution

to meet the increasing level o quality requirements. For example, modern equipment

with embedded power monitoring and communication can be implemented or betterand easier energy management. Variable speed drives are very adaptive tools or easier

process adjustment and more accurate process control.

Latest PLC technologies

Scalable migration is one o the key eatures oered by the Schneider Electric PLC

range :

existing Inputs/Outputs can be kept, a new generation o processor provides new

services and increases the perormance o the application,

even when all the hardware has to be changed, the sotware can be converted

and reused with the latest hardware to benet rom the new eatures.

All these upgrading eatures provide fexibility, high perormance and cost eectiveness

or the process control, and protect previous investments.
