Overview on the STATCOM Performance in the Power Quality Improvement in the Electrical Grid

摘要

The problem of controlling the transport of electrical energy has given rise to FACTS (Alternate Current Transmission Systems) systems to provide system stability, thereby improving controllability and power transfer capability. The STATCOM (Static Synchronous Compensator) is the FACTS device chosen in our paper. The main objective of this research study is to evaluate the performance of STATCOM as a static compensator of reactive power using the transmission line of electrical energy. The action of the Statcom in the electrical network disturbed by short circuit or overload, has shown its effectiveness in restoring the stability of a fault system by compensation of the reactive power by injecting a controlled current into the system in order to adjust the voltage at the connection nodes. We consider that the objective of this work is achieved through the results obtained which showed a clear recovery of defects after connecting the Statcom to the already disturbed electrical network.
