AI Technical Summary

Technical Problem

Existing technologies for controlling the conductivity of cooling water in generators cannot achieve rapid and precise stabilization near the target conductivity value, resulting in large control fluctuations and difficulty in effectively suppressing the copper corrosion rate.

Method used

By introducing a mixture of water from condensate polishing with ammonia and water from condensate polishing with ammonia as makeup water for the internal cooling system, and adjusting the mixing ratio of the two water sources using a preset functional relationship, the conductivity and pH value of the internal cooling system are gradually adjusted until the target conductivity value is reached.

Benefits of technology

It enables rapid and precise adjustment of the conductivity of the internal cooling water, reduces control fluctuations, shortens the system regulation cycle, and improves the safe and stable operation of the generator.

Abstract

The application discloses a generator internal cooling water optimization processing method, device and system, through obtaining a target conductivity value and a current water outlet conductivity value, and combining the relationship between the ammonia concentration and the conductivity of the internal cooling water, an adjustment amount of the water supplement conductivity control value relative to the current water outlet conductivity value is determined to supplement the internal cooling water tank; the operation is circular until the obtained conductivity difference value is less than or equal to a preset threshold value. The application is equivalent to realizing that the water supplement conductivity control value is determined according to the required ammonia addition amount of the current internal cooling water, so that the control of the water supplement conductivity control value can be more accurate, and the control fluctuation is greatly reduced and the system regulation period is shortened. In addition, through multiple sampling and circular execution, the current water outlet conductivity value can be gradually approximated to the internal cooling water target conductivity value in a progressive manner, and finally stabilized in the threshold range of the internal cooling water target conductivity value, so that the adjustment of the generator internal cooling water conductivity is more accurate.
