摘要
Abstract
In order to improve the working stability of photovoltaic power generation system,improve the cooling characteristics of photovoltaic thermoelectric coupling cooling system,this paper puts forward a based on phase change temperature control of photovoltaic thermoelectric spontaneous cooling system,using PID control to control the outlet temperature of the system,explore the temperature control of photovoltaic thermoelectric phase change embedded spontaneous cooling system.Firstly,we design the control effect of PID controller,discuss the influence of parameter characteristics on system performance,and finally analyze the space-time characteristics of the system.The results show that the selected Kp is-0.015 m·(s·K)-1,Ki is-0.05 m·(s2·K)-1,The PID controller with a Kd of-0.001 m·K-1 can effectively control the outlet water temperature of the system;The system temperature set point and the system fluid inlet temperature affect the system working characteristics by changing the initial deviation of the system,The greater the system's initial deviation,The higher the system overshoot volume,The longer the system adjustment time is,The smaller the steady flow rate of the system fluid is;The system achieves temperature stability after operation,Energy flows to balance,The power generation power of the thermoelectric components reaches 0.44 W,The photovoltaic power generation power reached 32.53 W.关键词
