The Application of the Distributed Measurement and Recording System Based on Wireless Technology for Start Debugging Process of EHV/UHV Transformer Substation

Abstract

Due to the low efficiency of preparation, long-distance electrical wiring easily causing safety accidents and other problems during the start debugging process of EHV/UHV transformer substation. A distributed measurement and recording system for start debugging process based on wireless technology is developed. The current and voltage signal of the substation is collected through each node, and then the collected signal is uploaded to the upper computer by the wireless local area network, so as to realize the transient state waveform recording and other functions. The test shows that the system can obtain the transient waveform and equipment state of each node not only in real time but intuitively. The working frequency is 5.8GHZ or 2.4GHZ, which can be covered about 2km.
