泰州电厂二期除氧器水位控制方案分析
|
摘要
除氧器水位是火力发电机组运行的重要调节参数之一,具有特殊的调节特性,其控制方式的选择一直是业界重视的课题。近年来,为了节约能源、降低厂用电率,多数电厂为凝结水系统配置变频凝泵,除氧器水位控制方式较常规工频凝泵有所不同。以泰州电厂二期为例,介绍了凝泵变频方式下除氧器水位的控制方案。
Deaerator water level is one of the important coal-fired power plant operation adjustable parameters. Due to its specialized regulation characteristic, its control method has always been an important issue in industry. In recent years, in order to realize energy conservation and plant consumption rate reduction, the majority of power plants have adopted variable-frequency condensate pumps for condensate system. Therefore, the control method of deaerator water level is different from that for conventional rated-frequency condensate pump. As a reference, this paper describes the selection of deaerator water control method with variable-frequency condensate pumps, using Taizhou power plant phase II as an example.
