Abstract In order to evaluate the temperature and humidity control effects in the underground powerhouses for a huge pumped storage power station, increase the design levels of operation environmental comfort and effects on the electromechanical equipment safety. These were analysed for the structure characters of the underground main powerhouse, generatrix cavern, main transformer cavern and air exhaust channel from Yixing pumped storage power station. Due to the performance parameters analysis requirements for the ventilation, inner air circulation and the temperature and humidity controls for the underground main powerhouses and main caverns, suitable measurement instruments were respectively chosen for the temperature, humidity and noise parameters, the measurement schemes were also designed respectively. After preliminary measurement and analysis, it is obtained that the measurement instruments chosen in the project are moderate price, high precision and convenient to use, meanwhile, measurement system and schemes could be satisfied with the temperature and humidity evaluation. Measurement instruments and schemes should be combined with powerhouse structure and air condition system requirements, and this paper can provide references for similar power station ventilation and air conditioning system measurement and performance analysis.
