Research of Adaptive Line Selection Leakage Protection Based on DSP in Mine

Abstract:

In view of the present our country coal mine high-voltage power grid widely used 6kV or 10kV cable direct power supply condition. To describe a DSP-based adaptive line selection leakage protection program of high-voltage power grid. It adopts under-compensation, adaptive random tuning and phase-sensitive comparison to judge the fault branch and achieve selective leakage protection, and make the protection system more perfect and reliable.
