哈三电厂600MW机组给水自动控制系统改进

Improvement of water supply utomatic control system for 600 MW power generators at Harbin No.3 power plant

针对哈三电厂国产600MW机组给水自动控制系统调节效果不好、温度保护频繁误动等问题,对自动调节系统、小汽轮机温度测点、给水泵温度保护系统进行了改进,提高了给水自动控制系统保护投入率、正确动作率和自动投入率,从而保证了机组安全、稳定和经济运行。

For poor regulating effect and frequent mishaps of temperature protection etc,of the water supply automatic control system for chinese-made 600 MW power generators at Harbin No.3 Power Plant,the automatic regulating system,the small turbine temperature measuring points,and the water supply pump temperature protection system have been improved to ensure the proper protection,operation and engagement of the water supply automatic control system so that the power generators will operate in a safe,steady and economic manner.
