    摘要:

    利用AMESim软件建立了某441.3 kW(600马力)液压动力站冷却系统的仿真模型。依据此液压动力站的散热原理,采用AMESim软件建立了以气-液换热器、双风扇、热负荷组件为主要分析对象的仿真模型,并利用软件内的控制元件和温度传感器组合,实现对风扇的智能控制。重点介绍了仿真模型中散热器和风扇的参数设置及其计算方法。分别在35和45 ℃的环境温度下进行仿真计算,得出不同温度下液压油的温度变化曲线。最后将仿真结果与现场检测的数据进行对比,验证了该仿真模型及参数设置的合理性,表明此模型能准确评估该系列液压动力站冷却系统的散热能力,为冷却系统的优化设计提供了参考。

    Abstract:

    The simulation model of the 441.3 kW (600 HP) hydraulic power station cooling system was established by using the AMESim software.According to the hydraulic power station cooling principle,the simulation model in which gasliquid heat exchanger,double fan,heat load components were taken as the main analysis objects was established by using AMESim software.The control elements and temperature sensors in the software were used to achieve intelligent control to the fan.The parameter setting and calculation method of the radiator and fan were introduced.The temperature variation curves of hydraulic oil at different temperatures were obtained by the simulation calculation at 35 ℃ and 45 ℃.Finally,comparing the simulation results with the field test data,the rationality of the simulation model and parameters setting was verified.It is shown that the model can be used to accurately evaluate the heat dissipation capability of series hydraulic power station cooling system.It provides a reference for the optimization design of cooling system.
