本文论述旁路系统的发展及其现状,提出旁路系统并非独立存在,它同机组的结构型式、运行方式、电网对机组的要求等有着极为密切的关系。本文介绍三用阀旁路系统的概况,阐明三用阀旁路系统在快速热态启动、滑压运行、电厂孤立运行(即机组带厂用电运行)等方面的特殊功能必要性,并就机组如何适应带厂用电的运行方式进行讨论,特别对FCB系统作了较详细的分析比较。论述了旁路系统的经济性问题。最后作者
This paper discusses the development of the bypass system and its status quo. It is proposed that the bypass system does not exist independently. It has a very close relationship with the structure type of the unit, the operating mode, and the requirements of the power grid on the unit. This article introduces the overview of the three-way valve bypass system and clarifies the special function necessity of the three-way valve bypass system in the areas of rapid hot start, sliding pressure operation, and isolated operation of the power plant (that is, unit operation with power plant) How to adapt the unit to run the way with the power plant for discussion, in particular FCB system made a more detailed analysis and comparison. Discusses the economics of the bypass system. Last author
