Energy Efciency: a common concern!

As electricity is te major contributor to greenouse gases, Energy Efciency is now a common concern for of allactors in te market.Reduce electricity consumption and costs and improve power quality and availability are now growing demands, moreparticularly due to: te commitment of many industrialised countries to reduce teir collective emissions of greenouse gases as wellas te implementation of local regulations and incentive scemes te increasing use of electronic devices leading to power quality issues and energy consumption rise

Energy Efciency thanks to power actor correction

Implementing power factor correction and armonic ltering solutions enable to: reduce your electricity bill increase available power reduce te impacts of armonics

Moreover, energy savings produced by power factor correction elp protecting te environment by reducing CO2emissions related to power generation.

The basis

The nature o energy

Active energyAll electrical devices powered by AC current convert te electrical energy supplied intomecanical work and eat.Tis energy is measured in kW and is called active energy. Te loads absorbing onlytis type of energy are called resistive loads.

Reactive energy

Some loads require magnetic fields to operate (motors, transformers, etc.) andconsume anoter type of energy called reactive energy.Tis can be explained as follows: tese loads (called inductive loads) absorb energyfrom te network wen te magnetic fields required to operate tem are generated andtey discarge it wen tese fields are destroyed.Tis transfer of energy between te loads and te source (fig. 1) causes voltage lossesand drops in conductors and terefore consumption of extra energy tat cannot bedirectly used by loads.

Power low in an installation

Te available power output of an installation increases indirectly as cosine increases.Te instantaneous power of an installation consists of two components: te oscillatingpower wose frequency is twice te fundamental frequency and te average power(Pm = VI cos ), wic represents te output or active power of te installation andwic is constant.Fig. 2 sows tat te more te cos of an installation increases (and te closer it is to1), te greater te average power of te installation.

Power actor (Cosine)

The presence of inductive loads in an installation causes a pase sift between tecurrent wave and te voltage.Te angle represents tis pase sift and gives te ratio between te reactive current(inductive) of an installation and its active current.Te same ratio exists between te active and reactive energies or powers.Te cosine terefore indicates te ratio between te active and apparent power ofte installation (te maximum number of kVA tat it can use).Tat is wy cosine indicates te electrical efficiency of an installation (fig. 3).

Practical calculation of reactive power

Calculations in te tree-pase example were as follows: Pn = power supplied to te rotary axis = 51 kW P = active consumed power = Pn/ = 56 kW

S = apparent power = P/cos = P/0.86 = 65 kVAence:Q = (S2 + P2) = (652 +562)6 = 33 kVAr

Te average power factor values for various loads are given below.

Increased available power

A ig power factor optimises te components of an electrical installation by increasing

teir electrical efficiency.Installing capacitors reduces reactive energy consumption between te source and teloads.Te capacitors supply reactive energy by discarging into te installation from teirupstream connection point.Te power available at te secondary of an MV/LV transformer can terefore beincreased by fitting a power factor correction device in te low voltage part.Te table in figure 5 sows te increased active power (kW) tat can be supplied by atransformer by correcting te power factor up to cos = 1.

Smaller conductor cross-section

Installing a power factor correction device in an installation allows te cross-section

of te conductors to be reduced, as less current is output from te compensatedinstallation for te same active power.Te table in figure 6 sows te multiplying factor for te cross-section of te conductoraccording to te cos of te installation.

Reduced losses

Reduced Joule effect lossesInstalling capacitors allows te Joule effect losses to be reduced (temperature rise) inte conductors and transformers.Te meter records tese losses as consumed energy (kW).Te losses are proportional to te square of te current.

Te following formula can be used to determine te loss reduction according to te cos of te installation:

Final losses = (initial cos )Initial losses final cos

Example:Loss reduction in a 630 kVA transformer, Pcu = 6,500 W wit an initial cos of 0.7.Wen by power factor correction, we obtain final cos = 0.98, te new losses become:3.316 W.

Reduced voltage drops

Installing capacitors allows te voltage drops to be reduced upstream of te pointwere te power factor correction device is connected.

Te location of te capacitors in an electrical network is determined according to: te required objective: eliminate penalties, discarge lines and transformers, increase end-of-line voltage, te metod of electrical power distribution, te load rating, te estimated effect of te capacitors on te network, te cost of te installation.

Te reactive energy compensation can be: a ig-voltage capacitor bank on te ig-voltage distribution network (1), a medium-voltage capacitor bank, regulated or fixed for te medium-voltage subscriber (2), a low-voltage capacitor bank, regulated or fixed for te low-voltage subscriber (3), fixed power factor correction for a medium-voltage motor (4), fixed power factor correction for a low-voltage motor (5).

Example:

When should ixed power actor correction be used?

Fixed transformer power factor correction

A transformer consumes a reactive power tat can be determined approximately by adding: a fixed part tat depends on te magnetising off-load current lo:

Qo = I0 x Un x 3

a part tat is proportional to te square of te apparent power tat it conveys:

Q = Usc S/Sn

Usc: sort-circuit voltage of te transformer in p.u.S: apparent power conveyed by te transformerSn: apparent nominal power of te transformerUn: nominal pase-to-pase voltage

Te total reactive power consumed by te transformer is: Qt = Qo + Q.

If tis correction is of te individual type, it can be performed at te actual terminals of tetransformer.

If tis correction is performed globally wit load correction on te busbar of te main switcboard,it can be of te fixed type provided tat total power does not exceed15% of transformer nominalpower(oterwise use banks wit automatic regulation).

Te individual correction values specific to te transformer, depending on transformer nominalpower, are listed in te table below.

Automatic power actor correction

Automatic power factor correction equipment

Internal componentsAn automatic power factor correction device must be adapt to te variations in reactive power of te installation inorder to maintain te target cos of te installation.

An automatic power factor correction device consists of tree main components: Te controller:Its function is to measure te cos of te installation and send orders to te contactors to ensure tat te powerfactor is as close as possible to te target cos by linking te various reactive power steps. Besides tis function,Scneider Electrics Varlogic controllers incorporate additional functions to assist wit maintenance and installation.

Capacitors:Capacitors are te components tat supply reactive energy to te installation.Capacitors are normally connected internally in a delta configuration.

External components

An automatic power factor correction device cannot work unless te installation data is collected; te externalcomponents ensure tat te device operates correctly:

Current measurement:A current transformer tat can measure te consumption of te entire installation must be connected.

Voltage measurement:Normally, tis device is built into te capacitor bank itself so tat tis value is generated by te power connection ofte capacitor bank.Tis information about te installation (voltage and current) allows te controller to calculate te cos of teinstallation at any time and to take te decision to activate or deactivate te power steps.

Te 230 V supply is also required for te capacitor bank control circuit.

Introduction

In electrical systems, te voltage or current waves, wose frequency is an integral multiple of te fundamentalfrequency of te network (50 hz), are called armonics.Te waves of different orders tat make up a armonic spectrum and result in distorted waves are generally foundsimultaneously.Fig. 25 sows te breakdown of a distorted wave into a sinusoidal wave at te fundamental frequency (50 hz) and awave at anoter frequency.harmonics are usually defined by two main caracteristics: teir amplitude: value of te armonic voltage or current teir order: value of teir frequency wit respect to te fundamental frequency (50 hz).Under suc conditions, te frequency of a 5t order armonic is five times greater tan te fundamental frequency,i.e. 5 x 50 hz = 250 hz.

Te root mean square value

Te rms value of a distorted wave is obtained by calculating te quadratic sum of te different values of te wave forall te armonic orders tat exist for tis wave:Rms value of I:I(A) = I

1 2+ I

2 2+ + I

n 2

Te rms value of all te armonic components is deduced from tis calculation:I (A) = I

2 2+ + I

n 2

Tis calculation sows one of te main effects of armonics, i.e. te increased rms current passing troug aninstallation, due to te armonic components wit wic a distorted wave is associated.Usually, te switcgear and cables or te busbar trunking of te installation is defined from te rated current at tefundamental frequency; all tese installation components are not designed to witstand excessive armonic current.

Detecting te problem in te installation

Instruments tat measure te true root mean square value (TRMS) must be used to detect any armonic problemstat may exist in te installations, since instruments tat measure te average value (AVG) only give te correctvalues wen te waves are perfectly sinusoidal.Wen te wave is distorted, te measurements can be as muc as 40% below te true rms value.

General inormation about harmonics (continued)

harmonic measurement: distortion

Te presence of varying amounts of armonics on a network is called distortion. It is measured by te armonic

distortion rates: T: individual distortion rateIt indicates, as a %, te magnitude of eac armonic wit respect to te value of te fundamental frequency:T (%) = A / A1wereA = te value of te voltage or current of te -order armonic.A1 = te value of te voltage or current at te fundamental frequency (50 hz).

ThD: Total harmonic DistortionIt indicates, as a %, te magnitude of te total distortion wit respect to te fundamental frequency or wit respect tote total value of te wave.

Te operating values used to find te true situation of te installations wit respect to te degree of armoniccontamination are: Te total armonic voltage distortion [ThD(U)] indicating te voltage wave distortion and te ratio of te sum of te

armonic voltages to te fundamental frequency voltage, all expressed as a %. Te total armonic current distortion [ThD(I)] determining te current wave distortion and te ratio of te sum ofte armonic currents to te fundamental frequency current, expressed as a %.

Te frequency spectrum (TFT) is a diagram tat gives te magnitude of eac armonic according to its order.By studying it, we can determine wic armonics are present and teir respective magnitude.

Interarmonics

Interarmonics are sinusoidal components wit frequencies tat are not integral multiples of te fundamentalfrequency (and terefore situated between te armonics). Tey are te result of periodic or random variations of tepower absorbed by different loads suc as arc furnaces, welding macines and frequency converters (variable speeddrives, cycloconvertors).

Long-term effects associated wit current overload tat causes overeating and premature deterioration of teequipment.

Affected devices and effects: Power capacitors:

Impact of armonics on capacitors

Choosing the detuned reactor tuning requency

General:

Te purpose of te detuned reactors (DR) is to prevent te armonics present on te network from being ampliedand to protect te capacitors (tis corresponds to our harmony range).Tey must be connected in series wit te capacitors.Caution: as te detuned reactors generate an overvoltage at te capacitor terminals, capacitors of at least 480 Vmust be used for a 400 V network.

Tecnical data:

Coice of tuningTe tuning frequency fr corresponds to te resonance frequency of te L-C assembly.fr = 1/ (2LC)We also speak of tuning order n.For a 50 hz network, we ave:n = fr / 50 hz

Te tuning order cosen must ensure tat te armonic current spectrum range is outside te resonancefrequency. It is also important to ensure tat no remote-control frequencies are disturbed.Te most common tuning orders are 3, 8 or 4.3 (2.7 is used for 3rd order armonics).
