Huawei AMI Solution

Forward

Consumers are more and more aware of the necessity to save energy in their home and

to get a consumer cost effective monthly bill. In the next step they are adopting not

only being consumers but also producers of energy, which would require an additional

infrastructure. Conventional manual metering approaches face some critical challenges

brought by the surge in power consumption and the expanding business scope of power

companies. Such as:

Cannot acquire and analyze real-time power consumption which is necessary for •

effective line loss analysis.

Low efficiency and errors and low accuracy are inevitable in manual meter reading.•

Cannot achieve pre-payment at multiple rates, remote control, or anti-power-stealing •

etc.

The key is to deploy Advanced Metering Infrastructure (AMI) in the power grids. AMI's up-

front benefit is its ability to facilitate a favorable interaction between power companies

and customers. To illustrate, it allows power companies to keep precise tabs on power

consumption and lets consumers take actions to optimize their power use.

Solution Introduction

As a leading global ICT solutions provider, Huawei has brought

its ICT extensive experience in the electric power industry into

the AMI solution that helps power companies leverage such

functions as smart metering, line loss analysis, and device-

based customer interaction. Such a solution promises better

user experience, power quality, and operating efficiency while

reducing consumption, carbon emission, and operating costs.

Huawei provides AMI solution consisting of a master station

– DCP (Data Collection Platform), WAN (Wide Area Network),

and NAN (Neighborhood Area Network).

DCP: The DCP contains a head-end system and a meter

data management system (MDMS). The head-end system

interacts with devices, manages communications protocols,

adapts internet protocols, and collects and stores metering

data. Thus, the Head-end system is also named Meter data

collection system(MDCS). The MDMS focuses on business

applications. It manages data analysis, monitors the operating

status of systems, compiles statistics, analyzes reports, and

manages operations and maintenance. Open interfaces will

enable the MDMS to connect with ISV systems, i.e. billing

systems (Billing), Supervisory Control And Data Acquisition

(SCADA), and Energy Management System (EMS). As an

integrated platform, Huawei DCP is adaptive to the united

network management platform to provide one-stop network

and business management services.

WAN: The WAN refers to the transmission network that links

the data concentrator unit (DCU) with the DCP. The WAN

supports various access modes, like GPRS/3G, Ethernet,

and medium-voltage PLC (power line carrier). Thus, specific

networks are utilized for different areas with particular

conditions. Huawei fulfills the diversified customer needs

with its professional wireless/fixed-line network solutions that

conform to power industry standards.

NAN: The NAN contains meters, DCUs, and communication

networks. NAN acquires and stores data of residential

consumer and commercial & industrial business customers

and transmits it to DCP systems for application level use.

The communication between Meters and DCUs in NAN •

are different based on application scenarios, such as

RS485, PLC, ZigBee, Sub-GHz or GPRS/3G directly.

Meters can integrate Huawei PLC chip, Sub-GHz chip or •

GPRS/3G chip.

Based on Huawei AR routing platform, provide "All-in-•

One-Box" features including wireless and wired interface,

firewall, routing, switching and VPN etc.

Customer value

Saving labor and operational costs

AMI enables automatic data

acquisition, reducing labor

cost and operational costs

since power companies do

not longer need to send staff

to read meters. AMI also

prevents unwanted economic

losses that are caused by manual data errors during manual

meter reading.

Reducing losses by restraining power theft

Smart meters and the DCP

work jointly to detect, analyze,

and identify attempts or

actions to steal power. As a

result, the AMI solution helps

restrain power theft and

reduces losses caused by it.
