发电厂凝结水泵采用变频调速的控制策略

The control tactics of using converter to regulation speed of condensate pump for power plant

文中介绍了某发电厂320 MW凝汽式汽轮发电机组进行凝结水泵变频改造的控制策略。通过系统分析和各项试验,解决了除氧器水位控制和2台凝结水泵联锁保护等技术问题,设计的控制策略完全满足改造后系统要求。其经验对于同类型机组进行凝结水泵变频改造具有一定借鉴意义。

This paper, introduce the condensate pump convert reform control tactics of condening turbogenerator in one 320 MW power plant. According to the system analysis and the factory test , sloved the level control of deaerator and the interlock protection of the two condensate pumps, The control tactics entirly meet the system demand. Also ,the paper has successful experience of condensate pump convert reform to this kind of power plant.
