摘要
发电机组保护对于保证发电厂主设备的安全运行至关重要。REG216数字式发变组保护装置在国内大型机组得到比较广泛的应用,取得了良好的效果。文中介绍了应用于国华宁海发电厂600WM机组的REG216数字式发变组保护装置的配置及特点,并对发电机差动、定子接地及PT断线保护原理做了详细说明,阐述了这些原理的优缺点。同时提出了一些REG216在发电机组保护应用及现场调试中应当注意的问题及解决方法。
The generator and transformer protection is very important to ensure the safety of power plant equipment, The digital generator protection REG216 has been generally applied in some large power plants. This paper proposes the configuration and feature of the digital generator protection REG216. The REG216 protection system has been applied to 600 WM units of the Guohua Ninghai Power Plant. Principles of generator differential, stator ground fault and PT fail protectcion are particularly commented. Some problems about the test and application of the locality are mentioned.
