Pumped storage power station is an economic and reliable means of peak load regulation for power networks. The temperature and humidity control are complicated due to the huge amount of heat and moisture emission in the main power plant. This paper investigates the operating condition of three different ventilation cases in a five-storey underground pumped storage power station. A full-scale model of the main plant was built for numerical simulation. Three ventilation cases were studied by changing the number, area and layout of air supply vents at the top of the main plant. The airflow distribution of three cases in summer condition were calculated and an optimal ventilation case was determined by comparing the jet flow range and temperature in the working zone. The working condition in winter was also simulated and verified in order to ensure the reliability of the ventilation case. Results show that case 1 was determined as a reasonable air supply case. In this paper, a reasonable scheme of ventilation system was proposed in a underground pumped storage power station. The results would be helpful to optimize the air ventilation mode in underground powerhouse of pumped storage power station.
