Research on Static Synchronous Compensator Design and the Switching Device Selection

Abstract

[Introduction] STATCOM is the state-of-the-art equipment for static reactive compensation. This paper focuses on STATCOM design study and key equipment selection principle for engineering applications. [Method] Five implementation approaches currently utilized to achieve large capacity STATCOM were analyzed and their advantages/disadvantages were concluded,from various perspectives including capacity, efficiency, reliability, volume and cost. [Result] Principles for selecting STATCOM switchgear were proposed and the application of the principles in 35 kV ± 200 MVA cascade STATCOM switchgear selection was also presented in this paper as an example. [Conclusion] The principles can also be used as reference in large capacity STATCOM design and manufacture.
