摘　　要：汽轮机凝汽器水位控制系统的设计一直是基建调试中容易忽视的问题,对一台350 MW汽轮发电机组的凝汽器水位系统进行了控制策略分析与设计,提出优化方案。控制逻辑中增加了闭锁出发逻辑,解决了电动补水阀的位置导致无效调节,以及两条管路的调节阀同时动作增加了设备损耗的问题。The design of the water level control system of the steam turbine condenser has been a problem that is easy to be neglected in the commissioning of the infrastructure. The control strategy analysis and design of the condenser water level system of a 350 MW turbo-generator unit is put forward. Control logic to increase the latch out of the logic to solve the location of the electric water valve lead to invalid regulation,and two piping control valve at the same time increase the equipment loss.
