Research on Airflow Parameters in the Generator Floor of a Pumped Storage Power Station During Summer condition

Abstract

This paper investigates airflow parameters for a pumped storage power station in Shandong. Continuous measurement was conducted for air temperature and humidity parameters at a height of 1.5m in the generator floor during summer. During test, three units operated and a supply air volume of 150,000 m³/h with 20.5°C and 90% RH was sent to generator floor. The results indicate that air parameters upstream and downstream of the generator floor satisfied the requirements of ≤30°C and ≤75%RH. Since the air temperature in the generator floor consistently remained below 24°C, which was significantly lower than the specified values, it is necessary to implement energy-saving control strategies for the air conditioning system to reduce operational energy consumption. The findings could provide reference for the energy-efficient design of the ventilation and air conditioning system in the main plant.
