An Innovative fuzzy based Power Quality Assessment of Distorted Electrical Power System

Electrical power quality evaluation is highly importantas penetration of renewable energy into the grid and uses of non linear load are drastically increasing in the modern era. There are different power quality indices which evaluates the power quality but it is highly essential to combine all the indices into a single value which can evaluates the power quality effectively. The innovative power quality index is found out considering the following component such as representative quality factor(RQPF), detailed pollution factor(DPF),total harmonic distortion(THD) and short circuit level(SCL).Fuzzy inference system has been implemented for doing the amalgamation of different power quality indices. In this paper THD module is formed by the amalgamation of total harmonic distortion voltage(THDV) and total harmonic distortion current(THDI) and THDSCL module is formed by the fusion of THD and SCL. The innovative power quality is formed by the mixture of THDSCL,DP and RQPF which has better significance both in quality and quantity point of view.
