新一代配电自动化系统助力新乡电网智能化

Core Viewpoint - The implementation of the "main-distribution coordinated grounding fault diagnosis" function in Xinxiang City, Henan Province, marks a significant advancement in the efficiency of handling grounding faults in the power distribution network, achieving precise isolation without power interruption [1][2]. Group 1: Technical Innovation - The new technology integrates data from small current grounding line selection devices in substations and zero-sequence current from distribution network switches to create an intelligent algorithm model [2]. - A collaborative diagnosis system is established based on "in-station line selection and out-of-station segment selection," transforming the traditional manual line inspection model and significantly reducing operational complexity [2]. Group 2: Operational Efficiency - The automated system enables a closed-loop management process encompassing "fault perception, diagnosis, isolation, and self-healing," promoting a shift towards safer, more efficient, and intelligent power distribution control [2]. - The recent practice demonstrated a rapid fault isolation within 19 minutes, restoring bus voltage to normal levels quickly, which enhances the reliability of power supply and equipment safety [1]. Group 3: Future Developments - The company plans to deepen the application of the next-generation distribution automation system and collaborate with Henan Electric Power Research Institute to further explore data value [2]. - The goal is to drive the digital and artificial intelligence transformation of power distribution operations, providing technical support for safe grid operation and high-quality service [2].
