摘　　要：针对舰船电力系统中非线性负载尤其是异步电动机负载较多,且发电机组数量多、容量小,需考虑其功率分配关系等特点,提出基于节点电势法的潮流计算改进算法。利用此算法对一个8节点的典型舰船电力系统模型进行计算,并通过Matlab软件仿真予以验证。结果表明,该算法具有计算精度高、收敛速度快等特点。In the shipboard power system, there are many nonlinear loads, especially in the asynchronous motors, and it has and it has lots of generators of low capability, which makes the relationship of power distribution to be considered. According to the characters of the shipboard power system, an improved power flow calculation algorithm based on the node voltage method is proposed. This algorithm is utilized to solve a typical ship board power system with 8 nodes, and the solution is proved by the simulation of Matlab. The result shows that this algorithm has the traits of high accuracy and fast convergence.
