摘　　要：随着电网负荷的峰谷差越来越大和供热机组容量的不断增加,给电网的稳定性和调度带来了较大的困难。由于供热机组受到供热负荷的限制,导致其低负荷调峰能力受到一定的影响。给出一种适用于不同工况、不同采暖抽汽量下较为简单快捷的供热式汽轮机调峰范围预测方法,并以某C330/262-16.7/0.49/538/538型汽轮机为例,对其在一段时间内的电功率进行了预测计算。所提出的预测方法对于供热机组参与调峰有一定的指导意义。With the increasing of electric power system peak-valley gap and the capacity of cogeneration unit,there are some difficulty for the stability and dispatching of the power system. The ability of peak load regulation of cogeneration unit is influenced due to the limitation of heating load. In this paper the load regulation range prediction method of cogeneration steam turbine is given,which is suitable for different conditions under the different heating load. Taking C330 /262-16. 7 /0. 49 /538 /538 type steam turbine as an example,the electricity load is predicted. The prediction method proposed in this paper has certain guiding significance for peak load regulation of cogeneration unit.
