Design and implement of measurement system for the testing of transmission lines based on wireless communication

Abstract

A set of measurement system for the testing of transmission lines, composing of wireless center station, wireless current acquisition and transmission nodes, wireless voltage acquisition and transmission node, was designed, which was based on wireless communication. The high speed wireless bridge working at 2.4GHz together with the clock synchronization module based on the IEEE1588 communicating protocol were both employed for the communication and time synchronization separately. The measurement system has data storage, waveform display, data analysis, automatic report generation and other functions. The test at a 500kV substation proves the validity and reliability of the measurement system. The measurement system can greatly reduced arrangement of cables, thereafter improved the test efficiency.
