摘要
依据上海电网内燃用天然气的9E系列联合循环机组的结构特点,对该类型机组在电网调峰中的角色进行了定位。分析了燃用天然气联合循环机组的技术经济特性并与300MW,600MW,1 000MW燃煤机组的经济性进行了比较,指出了燃气轮机联合循环发电具有能源综合利用和高效率的优点。在对9E级联合循环机组主设备运行可靠性分析的基础上,得出了9E系列的机组调峰运行可靠性优于其他类型机组的结论。
According to the structure characteristics of 9E-series natural gas-fired combined cycle units in Shanghai Power Grid,the role of these type units in peak load regulation of power grid was arranged.The technical and economical characteristics of natural gas-fired combined cycle unit were analyzed and compared with the economical efficiency of 300MW,600MW and 1000MW coal-fired units;and it was pointed out that the gas turbine combined cycle power generation has advantages of comprehensive utilization of energy and higher efficiency.Based on analysis of main equipment operation reliability of 9E-series combined cycle units,a conclusion was obtained that the reliability of 9E-series units in load regulation operation is better than that of other type units.
