本文提出了一种基于累积和的电力系统继电保护故障检测算法。文献表明，这种方法成功地应用于过程控制系统，其中跟踪参数的偏差以指示任何异常情况。在存在噪声、系统频率偏差等不确定性的情况下，该算法的有效性优于传统方法。它也不受系统中负载变化的影响。最重要的是，它提供了相对较高的指数值，而不会影响检测速度。
In this paper, a cumulative-sum-based fault detection algorithm is proposed for the power system relaying application. Literature suggests the successful application of this method to process control systems where the deviation of parameters is tracked to indicate any abnormal conditions. The effectiveness of the algorithm is found to be better than the traditional methods in the presence of noise, system frequency deviation, and other uncertainties. It is also not affected by load change in a system. Above all, it provides relatively higher index values without compromising detection speed.
