Abstract

This study deals with the admittance estimation algorithm for DVR for improvement of PQ in PDS (Power Distribution System). This admittance estimation algorithm based DVR is simple and easy to implement in simulation/hardware. In this admittance estimation algorithm, the estimation of active/reactive power components of load voltages are based on unit vectors in time domain and Low-Pass Filter (LPF). The mathematical analysis is easy, accurate and is used for fast estimation of reference load voltages using proposed algorithm. A three phase DVR using admittance estimation algorithm is modeled and implemented on real time hardware under balanced/unbalanced voltage sag, balanced/unbalanced voltage swell and harmonics compensation using Real Time Hardware Simulation and MATLAB under Simulink. Performance of admittance estimation algorithm for DVR in PDS shows quite satisfactory results using RT-LAB and MATLAB for the above power quality problems as per IEC and IEEE standards.
