复杂结构的舰船电力系统仿真算法研究

针对复杂结构的舰船电力系统的特点提出了一种新的仿真方法,该方法分为两部分:稳态计算和动态计算.稳态计算部分采用基于网络的节点电势法,充分考虑了线路压降对异步电动机参数的影响;动态计算部分将稳态计算的结果作为仿真初始值,采用变步长节点分析法求解微分方程.仿真和试验结果表明,该算法适用于辐射形、环形和网状形等任何复杂结构的舰船电力网络,方法简单、精度高、收敛性好,易于计算机实现.

Research on Simulation Algorithm of Complicated Warship Power System

In this paper,in the light of the features of a warship power system with a complicated structure,a new simulation method is proposed.The method includes two parts,i.e.static state computation and dynamic state computation.The former uses node voltage method based on a network and considers the heavy effect of the voltage drop along cables on parameters of a induction machine.The latter uses the result of the former directly as an initial value and solves differential equations by variable step node analysis.Simulation and test results show that the method can be applied to any one of warship power network with a complicated structure such as a radial,loop and meshed network,and it is easy to implement by use of a computer.
