Development and Application of Electromagnetic Disturbance Measurement System for Secondary Devices Port in GIS Substation
摘要
Abstract
In GIS substations,the intelligent secondary devices for protection are located either in the local control cabinet or near the GIS pipes.The devices for measuring and monitoring,such as electronic transformers,merging units,intelligent terminals,may fail during the operation of disconnector(DS)switching operations.The characteristics of the port disturbance voltage are indispensable for enacting the immunity requirements and protection measures.The onsite measurement is the unique approach to master the characteristics of the disturbance voltage,which may include:lots of high frequency components,ranging from several MHz to tens of MHz,even up to one hundred MHz;a short rise-time about nanoseconds;a duration time of a few hundreds of milliseconds.In this paper,by using the high speed digitizer as an alternative of the oscilloscope,optical fiber communication and the technical shielding box,a novel measurement system is developed.This system characterizes a smaller bulk,a lighter weight,a cheaper cost,a portable device and stronger anti-electromagnetic-interference.A series of tests,including DC high voltage,square wave,surge wave,and onsite measurement have been carried out to evaluate the performance of the system.These tests show that the system has specifications with max peak voltage 30 kV,risetime 5 ns.The system has been applied to measure in a 1 000 kV GIS substation.关键词
