国产300MW机组深度调峰运行的可靠性和经济性研究

Study on Reliability and Economics of Indigenous 300 MW Generating Units under Deep Cyclic Operation

电力工业所面临的是日益加大的峰谷电差，因此就必须加大占全国火电机组装机容量１／３的国产３００ Ｍ Ｗ 机组的调峰任务。外高桥电厂３００ Ｍ Ｗ 机组，在通过１６８ ｈ 试运行后即参与１２０ Ｍ Ｗ的调峰，为国内同类机组提供了良好的经验。

One of problems China's power industry facing now is ever increasing peak valley load difference.Hence the peaking duty of indigenous 300 MW generating units sharing 1/3 of national total thermal installed capacity must be increased.The 300 MW generating units of Shanghai Waigaoqiao Power Plant participated in cyclic operation of 120 MW immediately after passing 168 h of trial operation,providing good experience for the same kind units at home.
