摘　　要：提出一种综合高斯-塞德尔法和前推回推法两类潮流算法优势的大型船舶电力系统组合潮流计算方法.该算法将大型船舶电力系统分为主供电网络和子配电网络2个层次分别进行潮流分析.采用前推回推法对各子配电网络进行潮流计算,而在主供电网络分析层次中,将子配电网等效为注入功率源,采用高斯-塞德尔法求解潮流,两类算法相互利用对方潮流解算结果交替进行迭代计算,最终实现整个网络的潮流计算.对典型船舶电力网络进行了算法性能测试,给出了验算结果,并与传统方法相比较.结果表明,所提出的算法具有良好的收敛性能,求解大规模船舶电力网络潮流问题时较传统方法效率更高.A new load flow method for large shipboard power system with multiple generators which combined Gauss-Seidel method and forward-backward method is presented. In the proposed method, a shipboard power system is divided into a main power supply network and several radial distribution networks, which are deal with respectively. The forward-backward method is used to solve the power flow for each radial distribution networks, and the Gauss-Seidel method is used to solve the power flow for the main power supply network in which the radial distribution networks are equivalent to current injections. The two methods utilize the solutions of each other, and the final result can be ob- tained by iteration. Tests are conducted on a typical shipboard power system. The results validated the proposed method and demonstrate that it has better convergence on large shipboard power system network than tradition method.
