Abstract

Abstract

The multi-channel wireless shore power system with both parallel input and output can realize high-power transmission of ship shore power through modular superposition, and solve the problem of single-channel power limitation. However, some parameter differences and disturbances occurred in the process of module production, installation and operation will cause instability of the shore power output voltage and affect the reliable operation of the wireless shore power system. To solve this problem, a circuit topology was proposed firstly for the multi-channel parallel wireless shore power system. And then, taking the inverter phase shift angle as the input and the target load power as the output, a multi-channel parallel wireless shore power system model was established. Using a energy-phase angle method to reduce the system order, a small signal system model was established. Based on the Trapezoidal step bilinear approximation method, a system controller was designed to analyze the parameter differences of the channel coupling, DC input voltage and load disturbance separately. Finally, Matlab simulation and experiment were carried out to validate the control effect under the three disturbance conditions. The results show the better control effect of system controller, which can make a stable operation of the multi-channel shore power system. As a technical support, the proposed method is suitable for high-power wireless design and application of shore power system.
