Overview of the Key Points and New Technologies of Generator Stator Cooling Water Treatment

In view of the corrosion problem existing in generator stator hollow copper coil, the importance of controling the cold water quality and the main influencing factors of the stator copper coil corrosion are introduced, several main treatment methods and intelligent water distribution methods for the current generator stator cooling water are discribed, and each method is evaluated. In the operation of generator stator cooling water system, the pH and oxygen content of the cooling water should be stable for a long time, and the carbon dioxide concentration should be less than 1.5×10^-5 mol/L. The application effects of intelligent water distribution methods of generator stator cooling water are good water quality, low operating cost, stable and reliable long-term operation, and thus assuring the water quality being always within the best anti-corrosion range.
