摘要
针对船舶岸电无缝并网过程中出现的过流和继电保护误动作等问题,提出了一种基于改进二进制风驱动算法的船舶岸电并网故障诊断方法。分析船舶岸电系统的继电保护方案,在继电器、断路器拒动/误动条件下研究多种继电保护之间的状态关系及其对岸船电力系统的综合影响。选取适合船舶岸电电力系统故障诊断的数学模型,并利用改进的二进制风驱动算法对模型进行求解。最终,通过故障算例验证了该模型的合理性和改进算法的可靠性。
Aiming at the problems of over-current and maloperation of relay protection in the process of seamless operation of ship shore power,a fault diagnosis method based on the improved binary wind driving algorithm for ship shore is proposed.The relay protection scheme of ship shore power system is analyzed,the state relation among various relay protection under the condition of refuse operation/unwanted operation in relays and circuit breakers and its comprehensive influence on shore power system for ships are studied.The suitable mathematical model of fault diagnosis about shore power system for ships is selected and then solved by improved binary wind driven algorithm.Finally,the model is verified by two fault examples,and the rationality of the fault model and the reliability of the algorithm are fully proved.
