Abstract

Abstract

Single-phase inverter works in voltage source mode in rod position detection system of nuclear power plant. The load rod position detector is usually equivalent to a inductive load, but inductive load connected to the output of the inverter cannot output a stable sinusoidal voltage. In this paper, a proportional complex integral (PCI) control strategy is proposed for the power supply system of single-phase inverter rod position detector, and the parameter design method of the controller is given. First, based on the frequency domain model of the system, the analytical expressions of the parameters of the current loop proportional integral (PI) controller and the voltage loop PCI controller are derived, and the influence of the load parameters on the system stability is considered. Then, the expected open loop cut-off frequency and phase margin of current loop and voltage loop are set, and the PI and PCI controller parameters are analytically calculated by this method. Finally, through MATLAB simulation, it is verified that the proposed method can obtain stable output voltage and output current of single-phase inverter under inductive load, and the output current total harmonic distortion (THD) is less than 0.3%. This method can provide guidance for the power supply system control of single-phase inverter rod position detector.
