Performance of process bus communication of transient traveling waves data in smart substation
The transient traveling wave is mostly used in the areas of protections,fault line selections and fault locations due to its good characteristics of immunity to power swing,fault resistant,and CT saturations etc. The usage of transient travelling wave should rely on the real-time communications of SAV data,which produce the heavy load to the process bus in the digital substation. In response to this question,the performance of process bus communication of transient traveling wave data is analyzed,and the impact to the relay is also discussed in paper. It proves that the up to 77640Hz sampling rate is available for the real-time SAV transmission in the Lan speed of 100Mbps,which is limited by the process bus load capacity. The lower sampling data or transformed data (e.g. wavelet transform) should be used for the applications of travelling wave in digital substation. Although it is the first step of the research of the travelling wave usage in the digital substation,the work in this paper is good to the future constructions of the smart substation,which is based on the full-frequency signals fusion.
