Abstract

Abstract:

Since current prefabricated substations' real-time on-site monitoring function is simple, and remote operation and maintenance functions such as centralized monitoring and control are deficient,an online comprehensive monitoring system for prefabricated substations is proposed based on the information integration brought by Internet of Things.The system consists of a field layer,a platform layer and a presentation layer.The field layer takes the transformer comprehensive monitoring device as the core,which realize the data collection,analysis,display, control, alarm and other functions in its different blocks.The platform layer,as the coordinating center of the platform,consisting several micro services,achieves the collection and storage of data from the field layer and interaction with data from the presentation layer.The presentation layer which receives user requests and displays response data is the human-computer interaction interface for users.According to the practical results,the system shows excellent timeliness and intelligence in transformer monitoring.It is a flexible and economic method which effectively improves the operation and maintenance level and safety of prefabricated substations.

Key words: information integration of Internet of Things, fabricated substation, distribution, online monitoring, comprehensive evaluation
