11. STATCOM 2 July 2015 11 Comparable Synchronous Condenser Supply Variable Reactive Power And Voltage Regulate Principle of STATCOM

12. Application of STATCOM Act as an Active Filter. Controls the reactive Power with voltage support. Faster response to import power. Faster voltage regulation at load. High performance during low voltage condition. 2 July 2015 12

13. SVC 2 July 2015 13

14. Application of SVC Provide fast acting reactive power. Reactive power directly proportional to bus voltage. Faster response time. Enhance the transient stability margin. Enhance Voltage. Reduce voltage variation. Voltage control, Frequency Stabilization. 2 July 2015 14

15. SVC and TCSC Both builds a module ( Fixed Parallel capacitance + Thyristor controlled reactor). Reduce congestions and power overload in lines. SVC injecting or absorbing reactive power in order to control the voltage. TCSC modify the line impedance and control the power flow. 2 July 2015 15

16. UPFC 2 July 2015 16

17. Application of UPFC Simultaneously control 3 parameters(i.e., voltage, impedance, phase angle) and this unique capability is signified by the adjective “unified” in its name. It controls the voltage regulation, phase shifting, Series compensation. It control both the real and reactive power. Power flow control under power system oscillation and transmission line faults. 2 July 2015 17
