At the heart of this change is the smart substation—a responsive, near-autonomous, digital conversion hub that facilitates the frictionless exchange of power for a wide variety of assets, including EV charging stations, storage systems, and distributed and intermittent generation sources.
How a smart substation is developing?
As a major part of the smart grid, the smart substation has entered a comprehensive construction stage. The change mode of power grid development, the innovation and development of management model, the scientific and technological progress has put forward new requirements on the development of smart substations.
What is the metering system of a smart substation?
The metering system of the new generation smart substation is a digital energy metering system, which consists of an electronic voltage transformer, an electronic current transformer, a merging unit and a digital energy meter or a multi-function device integrated with a digital energy meter function and an electric energy collecting terminal.
What is smart substation research?
The new generation smart substation research focuses on overcoming the transformer equipment self-diagnosis, an intelligent device, station and wide-area protection and control systems, and other key technologies, significantly reducing the area and enhancing the safety, reliability, and economy.
What is new generation Smart substation?
The new generation smart substation will focus on new equipment, new materials, new technologies, primary electricity, and secondary light, which is characterized by power electronic technology and can rapidly achieve flexible control of energy and contains AC and DC mixed supply function.
What is a smart substation protection system?
Constitution and cooperation of hierarchical protection The new generation smart substation protection system adopts the hierarchical construction idea, synthesizes the panoramic data information of power grid, and constructs the hierarchical protection control systems consisting of the time dimension, space dimension, and functional dimension.
What is a smart Substation Network?
Based on the intelligent high-voltage equipment, the new generation of smart substation network is simplified from the current three-tier, two-network structure to a two-tier, one-network structure; according to the realization of different functions, the devices are classified into local and station control layers.
