摘要
介绍了一种基于甚高频测量技术和时延鉴别抗干扰原理的发电机局部放电在线监测装置,分析了装置采用的抗干扰方法。结合福建池潭电厂和广西柳州红花电厂的现场应用情况和试验分析,验证了该系统的测试效果及其抗干扰能力。通过技术经济分析,说明系统的建立有利于发电机组的安全运行和提高电站经济效益。
An on-line monitoring system for partial discharge of generators was introduced, which was based on the Very High Frequency （VHF） measuring technology and the time-delay identification anti-interference principles. The anti-interference methods applied to this system were analyzed. Considering the application experiences on site and the experimental analysis, the test results and anti-interference capacity were verified. Techno-economic analysis shows that the establishment of such system is conducive to improve the safe operation and the economic benefit for power generation units.
