At the same time, the reactive power also decreased from 12,964.1 var to 257.7 var. The compensated system has an apparent power of 10,415.9 VA and a distortion power of 1476.7 VA. The line current waveform of a load after compensation with an LC compensator is presented in Figure 13. Figure 13.
Reactive power is either generated or consumed in almost every component of the system. Reactive power compensation is defined as the management of reactive power to improve the performance of AC systems. Why reactive power compensation is required? 1. To maintain the voltage profile 2. To reduce the equipment loading 3. To reduce the losses 4.
This is a serious drawback, as the supply of reactive power by a capacitor drops when it is most needed; series capacitors are used to compensate for the inductive reactance of the loaded overhead power lines.
Use of capacitive (shunt compensation) on various part of the power system improves power factor, Reduce power losses, improves voltage regulation and increased utilization of equipment. Reference: Electric power generation, Transmission and distribution by Leonard L.Grigsby. Power system supply or consumes both active and reactive power.
The adaptation of the parameters of a passive compensator, reducing reactive power and/or distortion power, was possible through the extended Budeanu theory.
The inductive and capacitive reactances are frequency dependent (hence are only present in AC systems), oppose each other and are at right angles to the pure (DC) resistance. The net reactance, which is usually inductive, opposes the flow of current, and the power required to overcome this reactance is called reactive power (Q).
