大型船舶电力系统自适应保护算法设计

Design of adaptive protection algorithm for large ship power system

近年来,电力推进技术和船载电子设备发展迅速,对大型船舶的电力系统提出了更高的要求,电力系统的性能和可靠性对船舶的正常运行有重要的意义。由于船舶电力系统网络结构复杂、工作环境恶劣,电力系统很容易发生短路、单相接地等故障,而传统的继电保护已经难以满足现代电力系统的可靠性需求。本文针对大型船舶电力系统的可靠性问题,采用了自适应保护算法和自适应粒子群算法,对船舶电力系统的网络结构进行了优化。

In recent years,electric propulsion technology and the rapid development of shipborne electronic equipment,put forward higher requirements for power system of large ships,has important significance for the normal operation of the power system performance and reliability of the ship.Due to the ship power system complex network structure and poor working environment,easily occurs in the power system such as short and open circuit fault,and the traditional relay protection has been difficult to meet the demand of modern power system reliability.In this paper,the adaptive protection algorithm and adaptive particle swarm optimization algorithm are applied to solving the reliability problem of large ship power system.The network topology structure and reactive power efficiency of ship power system are optimized.
