Application of Wavelet Packet and Fuzzy Algorithm in Power System Short Circuit Fault Classification
Mathematical Problems in Engineering
Short-circuit fault, also known as a lateral fault, is one of the common types of faults in power transmission lines. This paper proposes an accurate method for identifying short-circuit fault types for power transmission line systems. According to the three-phase A, B, and C values, short-circuit faults can be subdivided into ten classes. An MDL power system with controllable short-circuit fault types is designed and tested. The method of using wavelet packet to analyze short-circuit faultdoi:10.1155/2022/2882456 doaj:4ea6b286b69b4b1ca4f6b752a84e6f12 fatcat:h3t6fxlyz5gtxfaf346r24xgpu
