Distributed Voltage Using Fuzzy Logic Control Comparison Of Electric Springs With Statcom

Ravindar Moodu, Ramavath Shankar Naik, Chennaiah Banoth


In this paper, a comparison is made between electric springs (ES) and static compensator (STATCOM). A comparison is made between distributed voltage control using ES against the traditional single point control with STATic COMpensator (STATCOM) by using fuzzy logic controller. Here we are using fuzzy logic controller instead of using other controllers. For a given range of supply voltage variation, the total reactive capacity required for each option to produce the desired voltage regulation at the point of common coupling (PCC) connection is compared. In this paper, it turns out that a group of ESs achieves better total voltage regulation than STATCOM with less overall reactive power capacity. Dependence of the ES capability on proportion of critical and NC load is also shown. Simulation was done by using MATLAB/Simulink software under various critical and NC loads.
