Abstract

The operational performance of static synchronous compensators (STATCOMs) under unbalanced and distorted system voltage is a great concern of designers and operation engineers. Based on a novel per-unit STATCOM mathematical model, this paper makes a theoretical analysis of STATCOM performance under distorted system voltage. Algebraic expressions as well as the 3-D curves are given to reveal the relationship between STATCOM harmonics and the main circuit parameters. The theoretical analysis was verified by digital simulation results of PSCAD/EMTDC and tests on a 10 kVAr prototype experimental device. The good agreement between the analytical results and the experimental results show that the approach proposed in this paper can be used to select the passive elements and assess the operation performance of STATCOM under unbalanced or distorted system voltage
