Digital Power Grid Construction Research of the Cross-regional Core Power Transmission Grid in Southwest China Based on Ubiquitous electric Internet of Things

Abstract

Abstract Digital power grid, as an important foundation for building a strong smart grid, provides the unified data management and service application by integrating multi-source data such as fundamental geography, geologic physiognomy, power grid subjects and projects. It has become an important branch of the “Ubiquitous electric Internet of Things” (UeIoT) construction. Southwest China with a vast territory, has complex terrain and geology conditions. With the orderly advance of the construction of the Ultra High Voltage (UHV) main grid in the area, the power grid data assets have been gradually accumulated. Thus it is necessary to build a digital power grid to solve the difficulty in power grid construction and data asset management. Based on the construction idea of UeIoT, this paper proposes a set of technical architecture for the digital power grid construction of the cross-regional core power transmission grid in Southwest China, and introduces the ideas and application schemes of the digital power grid platform construction.
