论文摘要
本文提出了一种基于相量测量单元（PMU）测量和交流功率流模型的电力系统中单线断电的方法。除了主要识别算法外，还引入了拒绝过滤器，以便可以进一步处理初步确定的结果并将其分为三种类型：正确识别，错误识别和确定性（包括正确的过滤和误识别的过滤）。这些方法是使用各种大小的测试系统进行系统测试的，用于各种PMU放置，结果表明，所提出的识别算法具有较高的识别精度，并且所提出的拒绝过滤器能够降低错误识别的速率，而无需显着增加不确定的情况。
This paper proposes a method of identifying single line outages in power systems based on phasor measurement unit (PMU) measurements and ac power flow models. In addition to the main identification algorithm, a rejection filter is introduced so that the preliminary identified results can be further processed and categorized into three types: correctly identified, misidentified and inconclusive (including correct-filtered and misidentified-filtered). The methods are systematically tested using test systems of various sizes for various PMU placements, and the results show that the proposed identification algorithm has a high identification accuracy and the proposed rejection filter is able to reduce the misidentified rate without significantly increasing the number of inconclusive cases.
