High voltage equipment in substations is a key component of smart grids. The abnormal temperature of these devices will lead to faults in the substation and even the entire power system. For substations, a widely employed, reliable, and maintenance convenient monitoring system is a necessary condition for online monitoring of the operating status of high-voltage equipment. This article designs a new type of self-powered RFID (SPRFID) temperature sensor tag and proposes a temperature monitoring system based on this new SPRFID temperature sensor tag. The introduced SPRFID temperature sensor can achieve long-term and long-distance temperature measurement in substations without batteries, which can reduce costs and maintenance pressure. The entire system was tested at a 110 kV substation, verifying its effectiveness and feasibility. The actual test results indicate that the monitoring system has high temperature monitoring accuracy and reliability.

摘要

High voltage equipment in substations is a key component of smart grids. The abnormal temperature of these devices will lead to faults in the substation and even the entire power system. For substations, a widely employed, reliable, and maintenance convenient monitoring system is a necessary condition for online monitoring of the operating status of high-voltage equipment. This article designs a new type of self-powered RFID (SPRFID) temperature sensor tag and proposes a temperature monitoring system based on this new SPRFID temperature sensor tag. The introduced SPRFID temperature sensor can achieve long-term and long-distance temperature measurement in substations without batteries, which can reduce costs and maintenance pressure. The entire system was tested at a 110 kV substation, verifying its effectiveness and feasibility. The actual test results indicate that the monitoring system has high temperature monitoring accuracy and reliability.
