摘要(Abstract):
对北仑电厂2号机组DAS系统主蒸汽流量指示值出现偏差的原因进行分析 ,找出原计算模块中存在的问题。将机组性能考核试验、循环效率试验的主蒸汽流量与DAS系统指示的主蒸汽流量值进行比较后 ,确定了新的主蒸汽流量与调节级后压力等测量参数的对应关系 ,并提出了对原计算模型的修改意见
Causes of deviation of the main steam flow value indicated in DAS system for Beilun power plant unit 2 are analysed.The problems are found in the original calculation model.Therefore,a new relationship is established between the main steam flow and the pressure after regulating stage based on the comparison of the main steam flow of the performance test and cycle efficiency test and the main steam flow value in DAS system.Finally,revision of the original calculation model is presented.
