Statcom Analysis With Closed Loop Pid And With Open Loop On Power System

Static synchronous compensator (STATCOM) is used in power system for better voltage control. The control should be possible using closed loop as well as open loop control. The closed loop control keeps precise voltage on the system during load variations. The Proportionate integrate derivative (PID) regulator used in closed loop is very significant for better control. The PID performance depends on its tuning parameters. This paper presents the PI D parameters tuning using pole placement and fuzzy method .The transient and steady state response of PID is compared with these two methods. Similarly the STATCOM analysis in open loop using load flow and its control of voltage on the systemis also present in this paper. Some times open loop control prefers to closed loop due to frequent load changes, unbalanced loads, time lag, fault constraints, etc.
