摘要
Abstract
A fault location method is proposed based on distributed traveling wave detectors of transmission line. With two sets of devices on high voltage transmission line based on Rogowski coil, high-frequency fault traveling wave could be measured. Application of phase-mode transformation and maximum technique of wavelet transformation modulus could help detecting the wave heads of aerial mode traveling wave and also acquiring their accurate arrival time. These time information would be uploaded to master station via wireless communication network. With the different time delay information, the master station would measure the on-line traveling wave velocity and accomplish accurate fault location for single transmission line. The high precision and reliability of the method are proved by the simulation results.关键词
