Design, Analysis and Implementation of a Small Signal Control Strategy on a 10 kVA STATCOM Prototype Connected to Inductive Load

摘要

Power factor on the supply side at point of common connection (PCC) can be improved through reactive power compensation using a static synchronous compensator (STATCOM). This approach is becoming increasingly popular in power system applications. In this paper, a small signal model of the STATCOM is practically implemented for maintaining unity power factor on the grid side in presence of inductive loads using a 10 kVA laboratory prototype. The designed controller is first simulated and then experimentally validated on the above laboratory prototype. Excellent agreement between the simulated and experimental results demonstrates the effectiveness of the proposed control strategy and highlights the accuracy of the experiments.
