自适应 S变换在故障测距的应用研究
Research of traveling wave fault location based on adaptive S transform
摘要
Abstract
S transform is widely used in fault location due to its time-frequency performance .But because S transform calculation uses the equal interval sampling frequency , so the calculation quantity is very large and there exists a contradiction between the speed and accuracy , namely improving the ranging accuracy must to increase the sampling frequency , but improving the sampling frequency will decrease the speed of com-putation, reduce real time.On the basis of this, an adaptive S transform is proposed to improve the computing speed , real-time performance and reduce occupied storage space based on the existing hardware .And the noise immunity of the method is verified .The experimental results show that the adaptive S transform can effectively improve the accuracy of the measurement system in the premise of ensuring the real -time performance of the system .关键词
