Grounding Fault Detection System of Substation Direct Current System Based on IP Technology
This paper proposes a grounding fault detection system for direct current system of substation based on Internet Protocol(IP)technology.The system uses IP network to build a fault detection platform,obtains fault signals through high-precision sensors,combines wavelet analysis and support vector machine to realize fault feature extraction and intelligent discrimination,and designs a friendly human-computer interaction interface.The simulation results show that the system can effectively detect and locate the grounding fault,which provides a new idea for the safe operation of direct current system.
