The Static Synchronous Series Compensation Devices Of Intelligent Pid Control Study

The paper first studies tratisiiiittcd power versus transmission angle characteristic, capability to exchange active power and immunity to resonance of Static Synchronous Series (ompensator(SSSC) bascd on its stcaty model, and discusses tho capability to control activo and reactive power. By means of vector analysis, dymazttic model of SSSC is deduced in dq orthogonal co-ordinate within synchronously rotating reference frame, and dynamic characteristics is invcstigatcd. To transform a voltage-control problem to a current-control problem, a current-controlled voltage-source inverter(CC-VSl) is considered, and a power flow controller based on Ph control algoritltnm is designed to improve dynamics of control system and implement closed-loop control to active and reactive power. To promote adaptation and robust, a self-tuned P1 power controller based on fuzzy rule is presented. Simulations prove it further improves the performance of P1 controller, amid enhances Ihe capability of SSSC to control power flow.
