1 POWER FACTOR CORRECTION The power factor correction of electrical loads is a problem common to all industrial companies. Every user which utilizes electrical power to obtain work in various forms continuously asks the mains to supply a certain quantity of active power, together with reactive power. This reactive power is not transformed or used by the user, but the electricity supply company is forced to produce it, using generators, wires to carry and distribute it, transformers, switching gear, and so on. A= P cosø Naturally, as the cosø increases, the size of the plant is reduced. 2) The Power Loss (Dp) on the line is given by: G Active power M Reactive power 1 Dp= K1 (cosø) 2 The natural consequence is that the electricity supply company requires users to comply with a minimum power factor (cosø) below which a surcharge is imposed. where K1 is a ratio coefficient. It is immediately clear that an increase in the cosø leads to a considerable reduction in the power loss (Joule effect), and so the plant will cost less and last longer. 3) VOLTAGE DROP (DV) on line is as follows: DV= K2 1 cosø G Active power M Reactive power where K2 is a proportionality factor. This case too shows that an increase of cos reduces the online voltage drop, thus producing a better performance of the users since the voltage along the line is closer to the rated power. Moreover, the power factor correction can have other important results. 1) For any given Active Power (KW) the Apparent Power (KVA) is in reverse proportion to the cosø. A power factor correction system is properly dimensioned when both the quantitative and the qualitative aspects are considered. Thus, knowing the following items is necessary: 1) the power factor correction rate to be installed to eliminate surcharges, thanks to the consumption analysis; 2) ambient conditions as well as rating of the mains the condenser is going to operate on, in particular if any harmonics are present in the line. 2

2 Calculating of the kvar required Distributed power factor correction 1) Threephase induction motor: it is one of the most commonly found loads. In table 1 here below the power factor correction power required. The advantage is a power supply cable run by a lower current. HP Rated power KW THREEPHASE INDUCTION MOTOR 2 poles 00 rpm operation without load poles rpm operation without load poles rpm operation without load poles 7 rpm Tab. 1 operation without load Centralised power factor correction To achieve a precise calculation of the power factor correction needs for a system, the following items are needed: the maximum used power and the cos of the system; these values may be calculated from the invoices of the electricity supplier or by carrying out the necessary measurements. After calculating the cos value desired in the plant, by means of table 3 the coefficient K is determined: it is used to multiply the used kws to calculate the power factor correction kvar. For example: a plant using P = kw with cosø = 0.70 requires power factor correction to cosø = From the table 3 we obtain K = 0.66, and so the plant requires Q = x 0.66 = 6 kvar, at the mains voltage. If the power of the proposed power factor correction system refers to a voltage different from that of the mains, it should be accounted for by means of the following: For motors having wound rotor, these values should be increased by %. QVrif= QVrete Vrif Vrete 2 2) Idle transformer losses: idle running of the MT/BT transformer, possible during the night or holidays, absorbs low cos power and needs to undergo power factor correction. The necessary power may be calculated from table 2 if the rated power of the transformer and its primary voltage are known. Tab. 2 KVAR required for power factor correction of the losses without load of a MV/LV transformer For example: if the power of 6 kvar amounts to V and the power factor correction proposed is 4V, at least the following will have to be considered: Transformer power KVA PRIMARY VOLTAGE 6 kv 16 kv = 799kVAr 2 to compensate the load. advanced technology for electrical installations 3

I.e., a current may arise such as to seriously damage condensers and other on line appliances. Knowing the short circuit power of the system (S in kva) and the power factor correction condenser power (Q in kvar), calculating the parallel resonance frequency is possible by means of the following: CONTROL SWITCH DISCHARGE RESISTOR CONDENSER Wiring diagram of antiresonance reactance battery fr = f1 S Q where fr and f1 are the parallel resonance frequency and the fundamental frequency (/ Hz). If the calculated frequency is near the frequency of a harmonic present in the system, a parallel resonance between condensers and system takes place according to the frequency of the harmonic. W 0 Inductive impedance 0 Capacitative impedance Behaviour of a condenser bank including an antiresonance reactance in relation to the frequency Hz 0 1 As shown in the picture above, in the case of frequencies higher than the reactancecondense frequency, the power factor correction bank is treated by the system as an inductance, thus eliminating the danger of a resonance within the distribution system Hz Resonance advanced technology for electrical installations
