Highlights
In recent years, rapid development in power electronics and control techniques has presented a new power electronic shunt compensation equipment with turn off switching capability
The device is called a Static Synchronous Compensator (Statcom). This device has a robust output and rapid response which can offer excellent contribution to the enhancement of power systems performance The basis of Statcom technology is the use of electronic switches in the form of a power converter that creates a voltage source to synthesize the Vc output voltage from a DC voltage source
By controlling the voltage Vc of Statcom, which is in phase with the system voltage Vs, but with a larger amplitude, the current and reactive power run from Statcom into the system, to raise the voltage
Summary
Rapid development in power electronics and control techniques has presented a new power electronic shunt compensation equipment with turn off switching capability. Statcom's main advantage over traditional SVC is its ability to generate completely capacitive current at extremely low voltage, something that SVC cannot do. Another advantage is its compact size, good harmonics, little or no filtering, better dynamic response, better transitions, less noise, and a lower magnetic field. The Statcom is a shunt connected device that is capable of generating and/ or absorbing reactive power. In these the output can be varied to control the specific parameters of an electric power system. The Statcom control scheme for grid connected wind energy generation for power quality improvement has following objectives.
