Abstract:
Electrical distribution systems are incurring large losses as the loads are more than average spread, inadequate reactive power compensation facilities and their improper control. A comprehensive static VAR compensator consists of capacitor bank in five binary sequential steps in conjunction with a thyristor controlled reactor of smallest step size. The work deals with the concert evaluation through related to studies and practical implementation on an existing system. A fast acting error adaptive controller is developed suitable both for contactor and thyristor switched capacitors. The switching operations courage are transient free, practically no need to provide inrush current limiting reactors, TCR size minimum providing small percentages of non triplen harmonics, facilitates stepless variation of reactive power depending on load. It is elegant, closed loop microcontroller system having the features of self-regulation in characterized by mode for automatic adjustment. It is successfully tested on a distribution transformer of three phase 50 Hz, Dy11, 11KV/440V, 125 KVA capacity and the functional feasibility and technical soundness are established.
