Fault Discrimination Using Synchronized Sequence Measurements under Strong White Gaussian Noise Background
Yagang Zhang, Zengping Wang, Jinfang Zhang · International Journal of Emerging Electric Power Systems · 2011
In this paper on strong white Gaussian noise background based on discriminant analysis theory, we mainly adopt synchronized sequence measurements of PMU to search for laws of electrical quantities marked changes. We have developed a method to quickly and accurately discriminate fault components and fault sections. The research has shown that the fault discrimination by discriminant analysis theory is effective and reliable. Under the interference of strong random white Gaussian noise, discriminant analysis still has high redundancy.
