Study on the Intelligence Structure of Current Differential Protection in Transmission Line of UHV Based on Agent

Zhenyu Chen

Abstract


At present, action criterions of Phase-segregated current differential protection in Transmission line of UHV include the criterion based on whole current, instantaneous value of fault and other changing from it. In different areas of fault, reach criterion has different reliability and sensitivity. On the basis of deeply analyses and study of the principle for Phase-segregated current differential protection, this paper combines intelligence Agent technology, and creates an intelligent protection structure which can choose reasonable action criterion according to the place of fault, and it can make the reliability and sensitivity of Phase-segregated current differential protection in Transmission line of UHV improved.
