An Energy Based Fuzzy Logic Dc-Link Voltage Controller For Three Phase DSTATCOM To Compensate AC Loads
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 10
Abstract
it is very important to compensate the transient response of DSTATCOM for unbalanced and nonlinear loads. Majorly the dc link voltage will be varied, when any small change in the load side. The proper operation of DSTATCOM is achieved with the help of the proportional integral controller (PI) is used. But the transient response of this controller is slow, Because the multiplication of the gains are more In this paper implement the energy based fuzzy logic controller with fast reference voltage generation to regulate Unbalance voltage in threephase system. Also improves the Power Quality of the 3- phase unbalanced and nonlinear loads. One of the main advantages of Fuzzy control over conventional controller is the inaccuracies of the sensors on the system performance can be reduced by adding additional rules, this reduces the need for costly sensors and cost of the control system is reduced without a compromise in performance. The simulation results show a very good performance.
