The problems including excessive flow of attemperating water for boiler, failure of butterfly valve at the outlet of circulating water pump, burnt-out of thyristor for excitation regulator, load variation rate of CCS ...The problems including excessive flow of attemperating water for boiler, failure of butterfly valve at the outlet of circulating water pump, burnt-out of thyristor for excitation regulator, load variation rate of CCS not complying with the contract target, etc. occurred during start-up and debugging of two 600 MW generating units in Yangzhou No.2 Thermal Power Plant. Through analysis on these problems. the remedial measures were put forward, to which can be referred for similar units.展开更多
随着1 000 MW机组大量接入500 k V电网,以及负荷中心220 k V电网分区后供电能力日益紧张,600 MW级机组接入220 k V电网的案例逐渐增多。结合湖北电网的实例,通过仿真计算研究了600 MW级机组接入220 k V电网可能带来的问题和应对措施,并...随着1 000 MW机组大量接入500 k V电网,以及负荷中心220 k V电网分区后供电能力日益紧张,600 MW级机组接入220 k V电网的案例逐渐增多。结合湖北电网的实例,通过仿真计算研究了600 MW级机组接入220 k V电网可能带来的问题和应对措施,并提出了应遵循的原则,相关结论和建议具有较强的实际借鉴和参考价值。展开更多
