Comparative Analysis of Types of Shunt Hybrid Power Filter Using Instantaneous Power Theory
نویسندگان
چکیده
The use of nonlinear load led to the injection of harmonics into the power system. In this paper, the performance of two topologies of shunt hybrid power filters for compensating voltage and current harmonics in the distributed power generation (DPG) system has been compared. The control algorithm used in this paper is the p-q theory for the harmonics compensation. The performance of these topologies are verified through MATLAB/Simulink for RL load. The THD of the power system is reduced to minimum tolerance level (< 5%) by the use of both hybrid filters. The THD of the power system is reduced from 30.26% to 5.05% and 4.57 % with the use of hybrid filter with parallel connected active and passive filters and with series connected active and passive filter respectively.
