Abstract

The invention discloses a ship power system self-healing method based on a pseudo-power discrete particle swarm algorithm, and the method comprises the following steps: S1, initializing a particle swarm, which comprises a random position and a random speed; s2, discretizing the particle group by adopting a pseudo-power probability greedy discretization method, and evaluating the fitness of each particle; s3, taking the discretized particle swarm as the optimal particle swarm as S4, and iteratively generating a next-generation particle swarm according to formulas (4) and (5); and S5, comparing the current particles, if the current particles are better, performing update, comparing the updated particles, if the current particles are better, resetting S6, if the current particles are not better, returning to the step S4, and if the termination condition is met, outputting a result, and ending the program.

Description

technical field [0001] The invention relates to the field of ship power systems, in particular to a self-healing method for ship power systems based on a pseudo-power discrete particle swarm algorithm. Background technique [0002] During the operation of the ship, the ship's power system failure and abnormal operation caused by damage, improper operation or equipment abnormality will cause damage to the equipment or even interrupt the power supply, endangering the safe and reliable operation of the ship. The installed capacity of the modern ship power system is constantly increasing, and the structure of the power system has also undergone major changes, mainly in the aspects of system configuration, grid structure, operation mode and control strategy. and so on put forward higher requirements. In order to meet the high reliability requirements of the ship's power system, the ship's power system fault self-healing as an additional optimization method for reconfiguration in...
