Research on the intelligent releaser of high voltage circuit breaker based on Dsp (I): The principle part of fault diagnosis and automatic reclosing phase selection

This paper introduces the principle part of fault diagnosis and automatic reclosing phase selection for TMS320VC5402 digital signal processor as the core of high voltage circuit breaker intelligent releaser. This releaser has the following functions: tripping function; Measurement function; Diagnosis function; Automatic reclosing phase selection function. It To has important practical significance to improve the level of the intelligent high voltage circuit breaker and development of our country electric power industry.
