摘要
针对发电厂继电保护设备故障样本数据较少,无法准确评估继电保护设备可靠性的问题,提出了灰色预测算法和三参数威布尔分布模型相结合的方法,用于评估继电保护设备可靠性,并通过实例仿真验证所提算法的可靠性.研究结果表明,所提出的继电保护设备可靠性算法可以根据少量样本数据快速评估继电保护设备的可靠性,与其他算法相比,预测评估精度较高,可以为继电保护设备的检修工作提供参考.
Abstract
There lack sufficient sample data of fault rate of plant protective relays for accurately evaluating reliability of relay protection.In this paper,a grey prediction algorithm combined with a three-parameter Weibull distribution model were proposed to evaluate the reliability of protective relays.Results show that the algorithm proposed in this paper can rapidly evaluate protective relay reliability based on a small number of sample data,has high precision,and can provide reference for maintenance of protective relays.
