摘　　要：本文介绍了1#机组进行凝结水泵系统变频改造的方案，利DCS实现电厂凝结水泵变频调速，改善凝汽器、除氧器水位自动调节品质，提出了两台凝结泵的联锁保护及相关问题的控制策略，并对改造后存在的问题进行了相应处理，取得较好节能效果，达到了预期。This paper introduces a project for No.1 unit with variable frequency governing system for condensate pump control, the system has gain electricity factory condensate pump variable frequency control with DCS. Improve controlling character of deaerator level and condenser level control. We put forward the control strategy for interlock protection between two Condensate Pumps and other questions, and solve many problem after finish the project. save energy and gain effect as expect.
