Research on Partial Discharge State Detection in GIS Based on Internet of Things Technology

Abstract

Abstract With the continuous development of the Internet of Things technology, the Internet of Things technology can be used in many aspects of the smart grid. Apply advanced Internet of Things technologies in substation GIS, including sensing technology, network communication technology, intelligent decision-making technology, automatic control technology, and energy and power technology, etc., and combine them closely to form a coordinated organic system. At present, partial discharge is the main cause of equipment insulation deterioration in substations. Partial discharge detection and evaluation has become an important means of monitoring insulation conditions. The monitoring of GIS partial discharge conditions in substations can help find insulation defects in GIS in time, avoid insulation failures, and improve the safe operation of GIS. It is possible to achieve GIS insulation condition maintenance, reduce power outage time and save maintenance costs. The effective application of the Internet of Things technology in the GIS partial discharge state detection system of intelligent substations can effectively improve the construction of modern intelligent substations in China.
