二次再热汽轮机组一次调频控制设计及应用

Design and Application of Primary Frequency Control for Double-reheat Steam Turbine

一次调频是汽轮机组控制系统快速响应回路的一个重要构成,是电网判定机组是否能安全、可靠运行的一个重要指标。文章对新型二次再热机组的一次调频功能的设计进行了较详细的介绍,并在现场进行了充分的试验,能为同类型机组一次调频功能的设计提供借鉴。

The primary frequency is an important component of the fast response circuit of the steam turbine unit＇s control system, and it is also an important indicator whether the unit can be safe and reliable. In this paper, the primary frequency function of the new type double-reheat steam turbine is introduced, and it has been carried out the full test in the site. The introduction may provide reference for design of primary frequency function of the same type unit.
