潜油电泵试验介质温度控制研究

Temperature Control Study to Test Medium of Electric Submersible Pumps

为将潜油电泵试验介质温度控制在规定温度范围内并提高控温精度 ,保护电泵机组 ,建立了电动潜油泵试验系统的数学模型 ,并在模型的基础上对介质温度的控制规律进行了研究。仿真结果表明 ,采用PI控制算法并引入非线性控制机制对高温试验装置内介质温度进行控制 ,具有良好的控制效果 ,可满足控温要求。

In order to control the medium temperature of electric submersible pump in fixed limits,increase the precision of temperature control and protect the pump set the author sets up the math model of the submersible pump test sysytem and on this basis studys the control rule of medium temperature.Simulation result shows that it has a fine control result and meets the needs of temperaturd control.
