本文讨论的问题，确定最佳位置的电压骤降监测器。所提出的方法是基于使用一个监视器到达矩阵的解析表达式，这是有效的电力系统中的任何位置的故障的解决方案。该方法提供了监测设备的最佳数量和最佳位置来放置它们，以保证考虑任何类型的故障（平衡或不平衡）的整个系统的可观测性。也就是说，通过所提出的算法获得的监测器的位置确保了导致电压暂降的任何事件被至少一个电压暂降监测器捕获。提供了几个例子，显示所提出的配方相比，其他方法的性能。
This paper addresses the problem of identifying the optimal location for voltage sags monitors. The proposed approach is based on using a monitor reach matrix obtained from the solution of analytical expressions which are valid for any location of faults in the power system. This method provides the optimal number of monitoring devices and the best positions to place them in order to guarantee the observability of the whole system considering any type of fault (balanced or unbalanced). That is, the location of monitors obtained by means of the proposed algorithm ensures that any event leading to a voltage sag is captured by, at least, one voltage sag monitor. Several examples are provided showing the performance of the proposed formulation compared to other approaches.
