Abstract: To improve the response speed and control stability of power transformer coil temperature control, a fuzzy PID-based power transformer coil temperature control method is studied. Based on the physical model of power transformers, a mathematical model for temperature control of power transformer coils is constructed. For the constructed mathematical model, the fuzzy PID control algorithm is used to control the temperature of the power transformer coil. The PID control part uses proportional, integral, and differential operations to control the coil temperature. The fuzzy control algorithm is used to set fuzzy rules for the PID control parameters, and the power transformer coil temperature control results are output through the fuzzy inference process. The results show that using this method, the coil temperature can be controlled at the target temperature within 0.1 seconds, with fast response speed and high control stability.

Keywords: fuzzy PID; power transformer; coil temperature; control methods.
