Investigate on the Design of Wireless Temperature Measurement System for Substation Busbar
Recently temperature measurement using wireless measurement system in switchgear becomes more and more popular, but most of them adopt polling method to build the wireless network which makes the measurement system with low efficiency and high power consumption. The TDMA technology with the characteristic of time-sharing processing and working on time series strictly, which will improve the efficiency of measurement system is studied in the paper. In order to meet the requirement of smart grid, the configuration of the wireless temperature measurement system is designed based on the standard of IEC61850 and the communication system fully compatible with the data transmission standard of new generation substation. Low power consumption technology is applied to solve the difficult problem-power supply. Taking the high capacity battery as example, the power consumption of the wireless temperature measurement system is calculated. The result show that the battery used in the measurement system has the lifespan more than 2 years, which ensure the measurement system can work reliably for a long time.
