抽水蓄能电站在机组调相及水泵工况起动时,需要将机组转轮室内的水体压至转轮以下,使转轮在空气中旋转。在这过程中,由于高压气体压力的瞬间释放,往往伴随着气体温度的骤然变化,这种变化将会对系统设备造成破坏性的影响。分析和研究水电站机组压水供气的热力学变化过程,可以使我们在系统设计和电站运行中采取相应措施,减小气体温度变化对于系统相关配套设备及管路可能产生的影响,以保证电站安全稳定运行。
Pumped storage power station phase modulation and pump conditions start, the need to run the water within the unit runner room below the runner, the runner in the air rotation. In the process, the instantaneous release of high-pressure gas pressure is often accompanied by a sudden change in gas temperature, a change that will have a devastating effect on the system equipment. Analyzing and studying the thermodynamic change process of the pressurized water supply of hydropower units can enable us to take corresponding measures in the design of the system and the operation of the power station so as to reduce the possible influence of the change of the gas temperature on the related equipment and piping of the system so as to ensure the safety of the power station Stable operation.
