Intelligent substation DC transformer control based on fuzzy PID technology

Intelligent substation DC transformer control cannot only improve the reliability and safety of intelligent substations, but also provide technical support for voltage regulation, power quality control, and other aspects. Therefore, an intelligent substation DC transformer control based on fuzzy PID technology is proposed. The equivalent circuit of the intelligent substation DC transformer is determined, the input voltage, input current, and power loss of each unit module of the equivalent circuit are calculated, and a mathematical model of the DC transformer is built. The signal of the intelligent substation DC transformer is collected, the collected signal is denoised using the CEEMDAN algorithm, and the denoised signal is input into the fuzzy PID controller to achieve DC transformer control. Experimental results show that the method has good control effects on transformer voltage and current, and the maximum control success rate is 98.5%. © 2023 Inderscience Enterprises Ltd.
