摘要：随着电网负荷峰谷差和供热机组容量的不断增加，电网的稳定性和调度面临较大的困难，为缓解这种情况，大部分供热机组需保证供热的同时参与电网调峰。对汽轮机工况图进行线性拟合，得到机组工况图的拟合函数，可根据当前采暖抽汽量、最大主蒸汽流量以及最小功率等信息，计算热电联产机组的调峰范围。此计算方法不需要现场的热力试验，工程上使用方便快捷，经实例验证，计算的调峰范围基本接近实际调峰范围。

Abstract:As the peak valley difference of grid load and the capacity of heating unit increase, the stability and dispatching of power grid are faced with great difficulties. In order to ease this situation, most of the heating units need participate in the peak load regulation while ensuring the heat supply. In this paper, a linear fitting of turbine working condition diagram was conducted and its fitting function was obtained, which could figure out the peak regulating range of cogeneration unit according to the information of current heating extraction flow, maximum main steam flow and minimum power, etc. This calculation method is convenient and rapid for engineering use because that the local thermal test is not required, and it was verified that the calculated peak regulating range is basically close to the actual range by living example.
