Design and simulation of matrix converter transformer for new ship power system

船舶电力系统因为其复杂性和特殊性,正经历着巨大的变革,尤其是在智能监测、故障预警和电力平衡等领域,各种先进的技术已经被广泛应用在其中。在船舶电力系统中,由于各种设备的用电需求并不一致,需要变压器把发电机端的电压转换成安全范围内的电压。因此本文借助Matlab仿真平台,重点研究变压器系统的基本结构,建立磁场模型,并分析在空载情况下的变压器状态,给出特性曲线。通过对节点导纳矩阵和变压器的等效电路进行变换,从而得到各个节点的电压电流变化。最后对变压器的励磁电流特性进行仿真与验证。

Because of its complexity and particularity,the ship electric power system is undergoing great change,especially in the field of intelligent monitoring,fault early warning and electric power balance,and various advanced technologies have been widely used in it. In the ship power system,because the demand for various devices is not consistent,the need to transform the generator voltage generator side into a safe voltage range. Therefore,this is the Matlab simulation platform,focusing on the basic structure of the transformer system,the establishment of a magnetic field model,and analysis of the transformer in the no-load case of the state, given the characteristic curve. Through the nodal admittance matrix, the equivalent circuit of the transformer is transformed to obtain the voltage and current change of each node.Finally,the excitation current characteristics of the transformer are simulated and verified.
