Research on actual measurement and treatment measures for condensation in Danjiangkou Hydropower Plant

Long-term humidity in the environment of the hydropower plant will lead to corrosion of electrical equipment, increase the probability of equipment failure, and affect the safe and reliable operation of mechanical and electrical equipment in the plant. In this paper, the air temperature and humidity of each part of Danjiangkou Hydropower Plant and the surface temperature of the plant wall and equipment pipeline are measured through the uninterrupted measurement for 6 months(from May to November). By analysing the temperature and humidity, condensation condition and air distribution of ventilation and air conditioning of each part, the causes of condensation on the surface of the plant wall and equipment pipeline are revealed. The optimization measure of the operation mode of the ventilation and air conditioning system to improve the condensation situation is studied without the renovation of the ventilation and air conditioning system. The actual measurement results show that the measure is simple and effective.
