摘要
辽宁大唐国际葫芦岛热电厂2×350 MW新建工程1号机组凝结水泵采用高压变频器进行凝结水变频调节,介绍了高压变频器的一拖一和一拖二的设计原理及工作模式,给出了凝结水系统各设备控制策略及逻辑组态,为同类型设备在设计及控制方式上提供借鉴。
The condensate pump of unit 1 of the 2×350 MW newly built project in Liaoning Datang international Huludao thermal power plant adopts high-voltage frequency converter to adjust the frequency of condensate water.This paper introduces the design principle and the working mode of one-drag-one and one-drag-two high-voltage frequency converter.The control strategies and the logical configurations of each equipment in condensate water system are given,which can be used for reference in the design and control mode of the same type of equipment.
