探讨电网中调峰电源的设置

目前,我国电网削峰填谷的任务日趋繁重,选择合理的调峰方式已成为需要认真探讨的一个问题,采用调峰改造的火电机组和建设一批大容量的联合循环机组作为调峰方式,能够取得良好效果.300 MW机组调峰改造投资省、见效快,而大容量联合循环机组具有优越的调峰性能,是电网调峰电源的最佳选择之一（气源充足、有保障的地区）.在机组参与电网调峰运行工况下,应关注机组的寿命损耗和电厂获得的经济效益.

Establishment of peaking power sources in electric network

At present,the problem how to keep balance between peak-load and off-peak load becomes more and more strenuous in China's electric network,and to choose a reasonable peak-load regulation design becomes a question needing careful consideration.As a peak-load regulation design,reconstructing thermal generating units for peak-load regulation and building a batch of large-capacity combined circulation units can obtain good results.The peak-load regulation reconstructions of 300 MW units can use less investment to gain better effects quickly.Large-capacity combined circulation units have superior peaking performance,thus becoming one of the best choices of peaking power sources in areas with reliable gas supply.During the peaking operation of the units,attention should be paid to the life loss of the units and the economic benefits of power plants.
