Abstract
Converter valve is the most important equipment in HVDC transmission system, but during the operation and maintenance of HVDC projects, electrical connectors overheat failures in converter valve equipments caused several unexpected trip events, which affects the safe and reliable operation of HVDC projects. Portable infrared temperature instrument is effective to surpervise the temperature of eletrical equipments in valve hall and prevent the overheat failure, but it is carried out manually. The electric company arranges oeprators to inspect the temperature of certain important equipments, which requires a lot of labor and has inspection blind aera. Therefore, on line temperature measurement system based on infrared radiation thermometer is proposed. The infrared temperature instrument performance is affected by ambient temperature seriously, in order to improve the accuracy of the measurement, this paper designs a novel infrared temperature measurement system with a silicon temperature sensor device embedde to provide valve hall temperature. This paper introduces the situation of converter valve equipments overheat failure and infrared temperature measurement technology, then a novel infared temperature measurement system applied in converter valve hall is proposed, both hardware and software design are addressed. At last, experiments are carried out to test the performance, which shows the embedded temperature measurement has high accuracy. Introduction From 2009 to 2018, 690 converter valve defects occurred in the converter stations under the jurisdiction of China Southern Power Grid UHV Company, of which 255 were overheat defects, accounting for 36.96%. The main overheat sites are connectors overheat, 233 items, and anode reactor overheat 10 items. From 2014 to 2015, 114 connectors overheat abnormalities occurred in the Fufeng, Jinsu, Tianzhong and Binjin converter stations under the jurisdiction of State Grid in China, of which 10 overheat cases caused temporary shutdown events. According to the statistics of the overheat parts, 44 were the converter valve reactor and parallel arrester connectors, accounting for 38.6%. The main reasons for the overheat problem are insufficient design margin, inadequate installation process quality and unqualified fittings quality. |
