The Substation Internet of Things System based on Edge Computing

Abstract

In response to the demand of the development of energy Internet for the comprehensive perception and wide interconnection of massive data of power system, the concept of ubiquitous power Internet of things(UPIoT), which comes from the deep integration of Internet of things technology and smart grid, has been put forward, becoming an important content and key link in the transformation and upgrading of power grid enterprises. The centralized computing mode previously adopted by smart grid can no longer meet the needs of large-scale computing and rapid response, so the ubiquitous power Internet of things should adopt the operation mode combining centralized computing and distributed computing. Firstly, this paper discusses the basic concepts and main characteristics of ubiquitous power Internet of things. Based on edge computing, this paper constructs the basic architecture of substation internet of things composed of perception layer, network layer, platform layer and application layer. Secondly, it discusses the key technologies in the construction of substation internet of things, and finally analyzes the specific application of edge computing in the construction of substation internet of things.

Applying Sensor-Based Phase Identification With AMI Voltage in Distribution Systems

“…Other types of sensors are also being installed at the distribution system level such as phasor measurement unit (PMU) devices, independently metered solar installations, electric vehicle (EV) metering, and smart relay devices. The wealth of sensors will only continue to grow as more internet-of-things (IoT) devices are incorporated into the power system [2]. Finding novel ways to leverage the newly available data from these sensors is a key task moving forward.…”
