摘要
在目前大容量调节抽汽式汽轮机组的不断投运以及电网仍然缺乏调峰能力的情况下,有必要使该类型机组更加深入地参与电网调峰,但是调节抽汽式汽轮机组参与电网调峰的能力严重受到其对外供热负荷的影响,为了得到该类型汽轮机的电负荷与热负荷之间的关系,针对目前运行的主要类型的调节抽汽式汽轮机,依据工况图对其热电负荷特性进行了分析,得出了调节抽汽式汽轮机在满足外界热负荷的情况下的电负荷特性,为合理安排该类型汽轮机组参与电网调峰提供了依据。
Due to the continuous operation of new large extraction turbines and the lack of peak regulation ability in the current electric network, it is necessary to let regulated extraction turbines participate more deeply in the electric network peak regulation. But the peak regulation of this kind of turbine is influenced heavily by its thermal load. In order to obtain the relations between electric load and thermal load, this text takes example for main extraction turbines in operation and analyses the characteristics of electric load and thermal load according to its working conditions chart , finally obtains the electric load characteristic in the condition of meeting external thermal load, and supplies the basis of regulated extraction turbine participating in the electric network peak regulation.
