STATIC SYNCHRONOUS SERIES COMPENSATOR
STATIC SYNCHRONOUS.pptx (Size: 172.21 KB / Downloads: 48) INTRODUCTION A static synchronous series compensator is a member of facts device which is connected in series with a power system. It consists of a solid state voltage source inverter which generates a controllable alternating current voltage at fundamental frequency. Without an energy source sssc can only inject a variable voltage, which is in quadrature with the line current. By using sssc we can control power flow in steady state and improve the transient stability of the system. Static voltage source converter If a dynamic change in a system will be occurred, sssc circuit works such that according to control circuit the energy of the battery will be converted to the ac form by converter and then injecting this voltage to the circuit the changes will be damped appropriately. Battery storage can also be connected to a series controller to inject a voltage vector of variable angle in series with the line. The energy source used in the voltage source converter is capacitor. The function of the series capacitor is simply to produce an appropriate voltage at the fundamental ac system frequency and quadrature with the transmission line current in order to increase the voltage across the inductive line impedence and there by increase the line current and transmitted power. CONCLUSION: In this topic , the power system stability enhancement of a two machine system by using sssc device is presented and also improves the dynamic response of the system. |
