波阻抗方向继电器的算法研究
RESEARCH OF ALGORITHM FOR SURGE IMPEDANCE RELAY
摘要
Abstract
According to the property that the surge impedance relay is realized by the ratio of voltage and current travelling waves, the relay's algorithm based on wavelets is present. The algorithm solves the problems of extracting travelling waves and constructing criterion. Its core is that multi-scale criterion is constructed with wavelet transforms. Theoretical analyses and EMTP simulations verify that the algorithm possesses many advantages such as precision, high reliability and immunity to noise. The algorithm can be implemented easily by digital manner.关键词
