摘要： 以阳城火电厂为例，在分析火电厂冷却水循环系统的基础上，将冷却水循环系统分为3 个水平衡层级，第一
层级为循环水塔与水循环系统（含旁流过滤系统）内部水量水平衡过程，第二层级为冷却水循环系统与反洗排水系统水
量平衡过程，第三部分为整个冷却水循环系统的水量平衡过程。针对三级循环系统进行水量平衡监测，通过技术手段获
得实时、动态的水平衡信息，数据结果可为提高火电厂循环水浓缩系数，减少新水补给提供数据支持，有利于火电厂节
约用水，减少企业投入，增加企业效益，为实现全厂冷却水循环的动态、实时测算，实现对全厂供水、用水、耗水、排
水的全面监控，快速定位水系统故障与故障位置提供了技术支持。

Abstract: Taking Yangcheng Thermal Power Plant as an example, based on the analysis of cooling water circulation system in
the thermal power plant, the cooling water circulation system is divided into three water balance levels. The first level is the
internal water balance process between the circulating water tower and the water circulation system (including the bypass filtration
system); the second level is the water balance process between the cooling water circulating system and the backwashing drainage
system; the third level is the water balance process of the whole cooling water circulation system. For the water balance monitoring
of the three-level circulation system, real-time and dynamic water balance information is obtained through technical means. The
data results can provide data support for increasing the circulating water concentration coefficient of the thermal power plant and
reducing the supply of new water. It is conductive to the thermal power plant to save water and reduce enterprise investment,
increase enterprise benefits, provide technical support for realizing the dynamic and real-time calculation of the cooling water
cycle of the whole plant, achieving comprehensive monitoring of the whole plant's water supply, water consumption, water
consumption and drainage, and quickly locating the water system faults and fault locations.
