摘要
按照某110 kV GIS变电站一次系统的实际结构与参数,采用数字物理混合仿真测试系统建立仿真模型,并接入站内真实二次保护装置,开展现场动模试验。试验全方位模拟了包括区内外金属性故障、发展性故障以及经过渡电阻短路在内的一次系统故障,充分检验了继电保护配置的合理性和可靠性,有效排查了保护死区,并完成现场断路器传动试验,确保变电站安全稳定地投入运行。
A self-developed digital physics hybrid simulation test system was used to establish the simulation model in this paper,according to the actual structure and parameters of a 110 kV GIS substation primary system.And real secondary protection devices were connected to the simulation test system to carry out on-site dynamic test.Full range of the primary system failure was simulated in the test,including metal failure inside and outside the protection area,developmental failure and short circuit through transition resistance.The reliability and rationality of relay protection configuration were fully verified.The protection dead zone was effective investigated and the on-site drive test was completed,ensuring the safe and stable operation of substation.
