Condition Assessment of MRTB Based on Fuzzy Theory

Abstract:

As one of the core equipment of high-voltage direct-current (HVDC) transmission system, the health status of MRTB would directly threaten the secure and stable operation of power system. Aiming at correctly getting the real-time operating status of MRTB , a new condition assessment method base on fuzzy theory is proposed and the corresponding device has been developed in this paper. After sampling the oscillating current, this method calculates arcing time by wavelet theory ,then fuzzy theory is used to judge the operating status of MRTB.
