摘　　要：为实现船舶交直流混合系统潮流方程直接可解,研究了基于潮流直接可解的船舶交直流混合系统PMU优化配置方法。在分析船舶交直流混合系统的结构及其潮流计算数学模型特点的基础上,将系统划分为交流子系统和直流子系统,并得到满足不同工况下潮流方程直接可解PMU优化配置方案。以102节点典型船舶交直流混合系统为例对所提方法进行了说明和验证,结果表明方法的正确性,可有效减少PMU配置数目,得到的PMU优化配置方案可为船舶交直流混合系统配置PMU提供参考。To make the power flow of shipboard hybrid AC/DC directly solvable,the optimal PMU allocation of shipboard hybrid AC/DC system based on directly solvable power flow was researched.On the basis of analyzing the structure of shipboard hybrid AC/DC system and the features of the mathematical model for its power flow calculation,the shipboard hybrid AC/DC system was divided into AC sub-system and DC sub-system to obtain the optimal PMU allocation scheme,which could meet the requirement that under different operating conditions the power flow equations were directly solvable.The proposed method was illustrated and verified by typical 102-bus shipboard hybrid AC/DC system.Calculation results showed that the proposed method was correct and the PMU numbers to be allocated could be effectively reduced.
