摘要现代船舶业高速发展，船舶电站的容量也快速增大，电力系统的结构也越来越复杂，传统的时间电流原则已经满足不了现代船舶电力系统保护性能的要求，因此针对电力系统的快速性选择性要求提出了自适应保护算法。84461
本文旨在研究电力系统的保护性能优化的自适应算法，通过对电力系统安全性能指标的快速性与选择性进行加权计算，并对两种性能指标进行权衡，对整个电力系统拓扑图结构进行分析，用退火粒子群算法对断路器的参数进行选择，最终实现电力系统保护性的优化，利用PSCAD对发电机和断路器的参数进行设置，并对几种舰船航行中的常用工况进行仿真，最后对时间电流原则的仿真数据和退火自适应优化算法的仿真数据进行了对比，通过实验验证了自适应算法的优越性。

Abstract Nowadays, the ship industry is developing at top speed, and the capacity of ship power system is becoming more and more large。 Besides, the structure of power system is demonstrating increasing complex。 Then, the traditional principles of current time can not meet the demands of protection performance in the modern ship power system any more。 Therefore, a kind of protection algorithm has been put forward for the requirement in speedability and selectivity of power system。
This paper mainly make a study on adaptive algorithms for protection performance optimization of power system。 It is weighted by calculating the speedability and selectivity of safety performance index in power system。 Then we need to balance these performance indexes, and make an analysis on topological structure of the whole system。 In addition, we also need to choose the parameter of circuit breaker by SAPSO, and realize the optimization of power system protection ultimately。 What’s more, we can use PSCAD to set the parameter of electric generator and circuit interrupter and make simulations of common use situation on several vessels。 Lastly, we make a comparison between the current time principle and SAPSO on the emulated data。 And then judge the superiority of adaptive algorithms。
