Abstract:

The Distribution static synchronous compensator is capable of reducing the losses and improving the voltage regulation in Multi Bus systems. The Distribution static synchronous compensator injects a current into the system to reduce the losses. The Distribution static synchronous compensator is capable of enhancing the reliability and quality of power flow in low voltage distribution network. A Distribution static synchronous compensator is one of the new generation flexible AC transmission system devices with a promising feature of applications in power system. The Distribution static synchronous compensator is used to stabilize the system voltage by exchanging reactive power with the power system. This work deals with the modeling and simulation of Fifty Bus systems with Distribution static synchronous compensator and the voltage sag is created by involving a heavy load. The sag is mitigated with Distribution static synchronous compensator. The circuit models and simulation results are presented. Voltages at various buses with and without Distribution static synchronous compensators are presented. The simulation results are compared with the analytical results. Fifty Bus System with multiple STATCOMs is modeled and simulated. The improvement in voltage stability with Distribution static synchronous compensator is presented. Voltages at various buses with and without Distribution static synchronous compensator are also discussed.
