随着电网峰谷差的日益增大和可再生能源发电量比重的逐渐增大，火电机组受到严峻的挑战。首先分析了某电网峰谷差情况，并将该省火电机组的负荷率与全国火电机组平均负荷率进行了对比。然后，以该省某600MW火电机组在2013年4个季节中的4个日负荷曲线为例，分析600MW火电机组在电网低谷期间的负荷率，并对该600MW火电机组的负荷率与电网峰谷差、电网最低负荷之间的关系进行了分析。最后，分析了600MW火电机组参与调峰对其经济性的影响，指出在电网低谷情况下，该600MW 火电机组发电标准煤耗率最高升高了17．7 g／（ kW· h）。

With the increase of the peak-valley gap in power system and the generating electricity from renewable energy , the traditional fossil-fired generating units face serious challenges .In this paper , the peak-valley gap in power system of a province is analyzed firstly , and the load rate of fossil-fired generating units in the province is compared with the national average.Then the four day load curves of a 600MW fossil-fired generating unit at the four season in 2013 in the province is taken as an example, the load rates of the 600MW fossil-fired generating unit during the low load of power system are analyzed, and the relationships between the load rate of the 600MW fossil-fired generating and the peak-valley gap rate and the lowest load of power system is analyzed too.Finally, analysis of the effect of the 600MW in peak adjustment of electric power on the economic is done , and the conclusion is obtained that the maximal value of standard coal consumption rate of electricity generating for the 600MW unit is 17.7g/(kW· h).
