摘要
频率是发电厂的一个重要运行参数,但是在发电领域,对于一次调频与二次调频的概念却有不同的理解。澄清了机组调频的概念,介绍了一次调频与二次调频的物理意义。分析了目前世界上主流汽轮发电机组的调频控制方案,对其优缺点进行了定性分析。对今后汽轮发电机厂优化设计以及运行人员操作机组具有借鉴意义。
Frequency is an important operating parameter of the power plant,but in the field of power generation there is a different comprehension for primary FM and secondary FM. This paper clarifies the FM concept and gives an introduction on the physical meaning of primary FM secondary FM. It also presents an analysis of the FM control schemes currently adopted by the world＇s major turbine generators with a qualitative analysis of its advantages and disadvantages in an attempt to provide a reference for future optimum design of designing of turbo generator plant and for unit operators.
