通过在调节范围内晚间有计划地卸负荷,启动在休假日甚至在夜里停机留作备用的发电机组,甩负荷直至空转以及为功频调节作计划外的波动等方法将发电机组用于调峰,在目前越来越广泛。将原来按基本负荷设计的大功率汽轮机在保证其可靠性和经济性的前提下用于这种工况乃是国民经济中一个重要课题。解决它需要探讨和采取一系列措施,其中包括改善变工况过程,改进汽轮机结构,改善启动方案,改进控制系统和对机组状态进行监控的设备等等。对于本文所述及的运行中的电站设备来说,由于汽轮机结构或启动系统的重大改变
The generator set is used for peak shaving by systematically unloading the load in the evening at a regulated range, starting the generator set on standby on holidays or even at night, waiting for load to idle, and unplanned fluctuations for power regulation , More and more widely at present. It is an important topic in the national economy that the high-power steam turbines designed according to the basic load should be used for such conditions under the premise of ensuring their reliability and economy. To solve it, it is necessary to explore and adopt a series of measures, including improving variable working conditions, improving steam turbine structure, improving start-up plan, improving control system and monitoring unit status. For the plant equipment in operation as described herein, due to significant changes in the turbine structure or starting system
