DEFINITIO

POWER FACTOR

By definition, the power factor, or the cos , of anelectrical device is equal to the ratio of the activepower P (kW) over the apparent power S (kVA) and canvary from 0 to 1.

It can thus be used to identify the level of reactiveenergy consumption of devices easily.

a power factor equal to 1 will result in a zero reactiveenergy consumption (pure resistance).

a power factor less than 1 will result in reactiveenergy consumption which increases as it approaches0 (pure inductance).

In an electrical installation, the power factor may bedifferent from one workshop to another dependingon the devices installed and the way in which they areused (offload, full-load operation, etc.).

Since energy metering devices measure the active andreactive energy consumptions more easily, electrical

utilities, have chosen to use the term tg on theelectricity bills of its customers.

IntroductionAn alternating current electrical installation, includingreceivers such as transformers, motors, weldingmachines, power electronics, etc., and in particularany receiver for which the current is out-of-phase inrelation to the voltage, absorbs a total energy calledthe apparent energy (E app).

Active energy (Ea): expressed in kilowatt hours (kWh).

It can be used, after being transformed by the receiver,in the form of work or heat. This energy corresponds tothe active power P (kW).

Reactive energy (Er): expressed in kilovar hours(kvarh). It is particularly used in motor and transformerwindings to create the magnetic field which is essentialfor operation. This energy corresponds to the reactivepower Q (kvar). Unlike the previous energy, this energyis said to be unproductive for the user.

This energy, which is generally expressed inkilovoltampere-hours (kVAh), corresponds to theapparent power S (kVA) and can be broken down asfollows:

For a single-phase supply, the term 3 disappears

Eapp = Ea +Er

Eapp = (P)2 +(Q)2

S=P +Q

S = (P)2 +(Q)2

Q = 3 U

For three-phase supply:

Tg calculation

cos =S(kVA)P (kw) Tgis the quotient between the reactive energy Er

(kvarh) and the active energy Ea (kWh) used during thesame period.

Unlike cos , it is easy to see that the value of tgmust be as low as possible in order to have theminimum reactive energy consumption.

The relationship between Cos and tg is given by thefollowing equation:

but a simpler method consists of referring to aconversion table (see p. 7).

ndecrease in the subscribed power in kVA

How to improve the power factor

ADVANTAGES

A good power factor is:A high cos (close to 1) or low tg (close to 0)

Improving the power factor of an electrical installationconsists of giving it the means to produce a varyingproportion of the reactive energy that it consumesitself.

Different systems are available to produce reactiveenergy, particularly phase advancers and shuntcapacitors (or serial capacitors for major transportnetworks).

The capacitor is most frequently used thanks to:its non-consumption of active energy,its purchasing cost,its easy use,its service life (approximately 10 years),its very low maintenance (static device).

The capacitor is a receiver composed of two conductingparts (electrodes) separated by an insulator. When thisreceiver is subjected to a sinusoidal voltage, it shifts itscurrent, and therefore its (capacitive reactive) power,by 90 forward the voltage.

Conversely, all other receivers (motors, transformers,etc.) shift their reactive component (inductive reactivepower or current) by 90 backward the voltage.

The vectorial composition of these (inductive orcapacitive) reactive powers or currents gives aresulting reactive power or current below the existingvalue before the installation of capacitors.

In simpler terms, it can be said that inductive receivers(motors, transformers, etc.) consume reactive energy,while capacitors (capacitive receivers) produce reactiveenergy.

FORMULA AND EXAMPLE

How to calculate the reactive power

FormulaReactive power Qc required for the compensation iscalculated from the active power (Pkw) and the tg measured on the installation.These measurments are performed downstream thesecondary of the transformer.

ExampleTake a plant powered from an 800 kVA HV / LVsubscriber station which would like to change thepower factor of its installation to:* Cos = 0.928 (tg = 0.4) on the primary winding* or Cos = 0.955 (tg = 0.31) on the secondarywindingwith the following readings:voltage: 400 V three-phase 50 Hz

P = 475 kWCos (secondary) = 0.75 (or tg = 0.88)

Qc (bank to be installed) =Pkw (tg measured - tg to be obtained)

= Pkw x K*

* K is obtained from the table page 7.

Example: 200 kW motor - cos = 0.75 - Desired cos = 0.93 - Qc = 200 x 0.487 = 98 kvar

Qc = 475 (0.88 - 0.31) # 270 kvar

To guarantee its operation, a transformer needsinternal reactive energy required for the magnetisationof its windings. The table below gives a rough guide ofthe value of the fixed bank to be installed according tothe powers and loads of the transformer. These valuesmay change according to the technology of the device.Each manufacturer is able to give their precise values.

LEVELS OF INSTALLATION

The table below gives a rough guide of the maximumcapacitor power which can be connected directly to theterminals of an asynchronous motor without a risk ofself-excitation. In any case, it will be necessary to checkthat the maximum capacitor current does not exceed90% of the magnetising current (off-load) of the motor.

Advantages:No reactive energy bill.Represents the most economical solution since

all the power is concentrated at one point and theexpansion coefficient makes it possible to optimisebanks.

Relieves the transformer.

Remark:The losses in the cables (RI2) are not reduced.

Advantages:No reactive energy bill.Relieves most of the line feeders and reduces Joules

heat losses (RI2) in these feeders.Incorporates the expansion of each sector.Relieves the transformer.Remains economical.

Remark:Solution generally used for a very large plant

network.

Advantages:No reactive energy bill.From a technical point of view, the ideal solution

since the reactive energy is produced in the sameplace as where it is consumed; therefore, the Joulesheat losses (RI2) are reduced in all the lines.

Relieves the transformer.

Remark:Most costly solution given:

- The high number of installations,- The non-incorporation of the expansion coefficient.

However, if the capacitor power required tocompensate the motor is greater than the valuesindicated in the above table or if, more generally:If Qc > 90% Io 3 U, compensation at the motorterminals remains possible by inserting a contactor(C.2) controlled by an auxiliary motor contactor contact(C.1) in series with the capacitor.

Qc The reactive power supplied by the bank is constant

irrespective of the variations of the power factor andload of the receivers and, therefore, of the reactiveenergy consumption of the installation.

These banks are switched on:- either manually by a circuit breaker or switch,- or semi-automatically by a remote-controlled

contactor.This type of bank is generally used in the followingcases:- constant loadelectrical installations operating24 hours a day,- off-load compensation of transformers,- individual compensation of motors.

The reactive power supplied by the bank can bemodulated according to the variations of the powerfactor and the load of the receivers and, therefore, ofthe reactive energy consumption of the installation.

This type of bank is composed of a parallelcombination of capacitor steps (step = capacitor +contactor). They are switched ON and OFF by anincorporated power factor controller.

These banks are generally used in the followingcases:- variable loadelectrical installations,- compensation of main switchboards (LVMS) or majoroutlets

In addition to the internal protective devicesincorporated in the capacitor:- self-healing metallized polypropylene film,- internal fuses,- overpressure disconnecting device ;it is essential to provide an external protective deviceon the capacitor.

This protection will be provided either:

by a circuit breaker:- thermal relay, setting between 1.3 and 1.5 In,- magnetic relay, setting between 5 and 10 In.

by GI type HRC fuses, rating 1.5 to 2 In.

Applicable capacitor standards are defined so thatcapacitors can withstand a permanent excess currentof 30%.

These standards also authorise a maximum toleranceof +10% on the nominal capacitance.

Therefore, the cable should be designed at least for:I cable = 1.3 x 1.1 . (I nominal capacitor)

Harmonics

Reactive energy compensation means thatthe capacitor must be adapted to the intrinsiccharacteristics of the corresponding mains network(voltage, frequency, cos , etc.). However, theincreasing presence of harmonics in the mains supplymeans that the capacitor must also be adapted tothe degree of interference and the final performancedesired by the customer.

SH(kVA) is the weighted total power of the harmonic generators present at the transformer secondary.

INTRODUCTION

The modernisation of industrial processes, thesophistication of electrical machines and equipmenthas, in recent years, led to significant development inpower electronics:

These semi-conductor-based systems (transistors,thyristors, etc.) designed to produce:solid state power converters: AC/DCrectifiersinvertersfrequency convertersand many other wave train or phase setting controldevices.

For electrical supplies, these systems represent non-linear loads. A non-linear load is a load for whichthe current consumption is not the reflection of thepower supply voltage (even though the source voltageon the load is sinusoidal, the current consumption isnon-sinusoidal).

Other non-linear loads are also present in electricalinstallations, in particular:variable impedance loads, using an electric arc:arc furnaces, welding stations, fluorescent tubes,discharge lamps, etc.

loads using strong magnetising currents:saturated transformers, inductors, etc.

The FOURIER series breakdown of the currentconsumption of a non-linear receiver reveals:a sinusoidal term at the supply 50 Hz frequency, thefundamental.sinusoidal terms for which the frequencies aremultiples of the frequency of the fundamental, theharmonics.

According to the equation:

These harmonic currents circulate in the source andthe harmonic impedances of the source produceharmonic voltages according to the equationUh = Zh x Ih.

Harmonic currents induce most of the harmonicvoltages which cause the overall harmonic distortion ofthe supply voltage.

Note: The harmonic distortion of the voltage generated by manufacturingdefects of the alternator and transformer windings is generally negligible.

DETUNED REACTORS AND CAPACITORS

HARMONIC FILTERS

Harmonics (continued)

Protection of capacitorsFor supplies with a high level of harmonic interference,installing a detuned reactor connected in series withthe capacitor proves to be the only effective solution.

Influence of harmonics on capacitors

For installations with a high level of harmonic pollution,the user may be confronted with two requirements:compensating for reactive energy and protecting thecapacitorsreducing the voltage distortion rate to acceptablevalues compatible with the correct operation ofmost sensitive receivers (automatic control systems,industrial computer hardware, capacitors, etc.).For this application, Legrandis able to offer passivetype harmonic filters.

A passive type harmonic filter is a serial combinationof a capacitor and an inductive coil for which eachcombined frequency corresponds to the frequency of

an interfering harmonic voltage to be eliminated.

For this type of installation, Legrandoffers servicesincluding:analysis of the supply on which the equipment is tobe installed with measurements of harmonic currentsand voltagescomputer simulation of the compatibility of theharmonic impedances of the supply and the differentfilterscalculation and definition of the different componentsof the filtersupply of capacitors, inductive coils, etc.measurement of system efficiency after installationon site

DETUNED REACTORS AND CAPACITORS

Xc = C.1

= C.2. .f1

The reactance of the capacitor

is inversely proportional to the frequency, its curve is

reciprocal and its ability to block harmonic currentsdecreases considerably when the frequency increases.

Harmonic currents being located at high frequencies,consequently they are diverted to the capacitor: thecapacitor is acting as a harmonic pump.

To prevent the capacitor to be damaged it iscompulsory to protect it with a detuned reactor.

Scc (kVA): Short-circuit power of sourceQ (kvar): Capacitor bank powerP (kW): Non-interfering load power

Note: since the inductance of the motor is much higher than that of thesource, it becomes negligible in a parallel assembly.
