PRINCIPLE AND CHARACTERISTICS OF A FAULT CURRENT LIMITER WITH SERIES COMPENSATION

A fault current limiter with series compensation, which is composed of a compensation capacitor and a limiting reactor in series, is propose d. A solid-state switch connected in parallel with the capacitor contr ols either the ordinal series compensation or fault current limitation . A feasibility study of the current limiter by simulation analysis is presented and the effectiveness of the current limiter is evaluated f rom the viewpoints of transient stability improvement and device capac ity. The current limiter is a useful protection device for large, high power transmission systems.
