基于调节级压力的汽轮机最佳滑压运行方式
Optimal Sliding Pressure Operating Mode of Steam Turbine Based on Governing Stage Pressure
摘要
Abstract
In allusion to the problem of deviation of the sliding pressure curve of power plant unit with changes of external conditions, this paper presents a kind of sliding pressure curve taking governing stage pressure as the independent variable by combining variable condition theory of the steam turbine. On the basis of this curve, it puts forward a control method for optimal sliding pressure operating mode which can overcome affect of changes of thermal parameters such as heating-extraction capacity and exhaust pressure. This method adopts a self-adaptive control mode of gradual approximating which means general adjustment firstly and then accurate adjustment. By using this method, it is able to keep rapid response speed and be convenient for implementation in the distributed control system (DCS) in power plant so as to accurately adjust operating condition of the steam turbine and improve operating economy of the unit.关键词
