Power Quality Improvement by Using Active Power Filter and STATCOM of Renewable Power Distribution System

摘要

In this modern world use of non-linear load is increases rapidly. Every daily need equipment use of non-linear load is existence. Non-linear loads affect the power quality of the power systems. An active power filter executes with four- leg voltage source inverter (4L-VSI) is demonstrated. Combination of Active power filter and STATCOM with fixed and variable switching frequency combination demonstrated in this paper. This system also mitigates unbalance current generated by non-linear load as well as allows the current harmonic components compensation. A simple mathematical model of active power filter and STATCOM presented with a prediction control algorithm with derivation of power system impedance. The performance of active filter and STATCOM compensation technique presented here with the simulation results.
