摘要
文章对继电保护系统在计算机、通信和数字信号处理技术的带动下走向信息化的发展过程进行了介绍,其中特别对小波变换在DSP中的应用作了分析。最后,就有关继电保护信息化的一些问题,包括信息共享对安全的影响进行了讨论。
The development trend of power system protective relaying under the promotion of the technique of the computer, the communication and the digital signal processing is presented in this paper, especially the application of the wavelet transform in DSP is analysed. Finally, some problems related to applying information technology(IT) including the influence caused by information sharing are discussed.
