Research on Working Mode of Intelligent Terminal of Distribution Automation Based on Public Wireless Communication Network

Abstract

Targeting the situation that the wireless communication terminal commonly exists in the pilot project of distribution automation has an unstable power supply under extreme conditions, this paper proposes a non-real-time online working mode that is different from the traditional real-time online working mode. The switching method of the two working modes was designed, and the comparison and analysis between the two working modes were performed in terms of the timeliness of event active reporting, communication flow, the impact on the processing mechanism of the master station system and the impact on the working duration of the power supply. The results show that the average power consumption of the wireless communication terminal under the non-real-time working mode is reduced from the watt level to the mill watt level, thus the power supply problem of the wireless communication terminal under extreme conditions is solved.
