Abstract :
Online monitoring and fault diagnose system of electrical device is one of the main research directions in the electric field. It is also one of the key technologies for settling the decision problems of reliability, safety and maintenance. STATCOM is a kind of large Flexible AC Transmission System device which is used more and more widely. As its cost and complicated degree are high, it is especially important to build an OMFDS for STATCOM. However, as it is not a hot study problem, the current relative research work is a little. This paper states the basic theory of OMFDS and emphasizes three kinds of key technology, analyzes the particular characteristics for OMFDS application on STATCOM, concludes common fault types of STATCOM, such as power capacitor fault on DC side, bridge arm shoot-through fault, power electronics switch devices fault and so on. Finally it introduces the basic configuration and construction of hardware and software of OMFDS in STATCOM.
