Power Quality Improvement By Svc Using PIC18F4
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Power quality improvement for non linear loads is the point of interest for researchers in recent years. Power factor plays an effective role in efficiency of electrical system. In power system the voltage level at different system changes with the change in load. The voltage level at the load must be maintained within required range irrespective of the type & magnitude of the load. For maintaining voltage fixed within limits, it is necessary to maintain the balance of reactive power in the system as reactive power is related with voltage directly.i.e reactive power generation and absorption must be equal. Any mismatch occurs in the reactive power balance affects the bus voltage magnitude. A static VAR compensator include capacitor bank in different binary sequential steps in conjunction with a thyristor controlled reactor of minimum step size is used in the investigative work. The work related with the performance evaluation through analytical studies and practical implementation on an existing system consisting of a distribution transformer of 1 PH phase 50 Hz, 1KV/230V capacity. The switching characteristics achieved are transient free, practically no need to provide inrush current limiting reactors, TCR size minimum providing minimum percentages of nontriplen harmonics, facilitates stepless variation of reactive power depending on load requirement , thus maintain power factor near always unity .
