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.

How does solar-powered air conditioning work?

Solar-powered air conditioning works a lot like conventional air conditioning — it sucks heat out of the air in your home, releasing it outside, to...

What is a substation & how does it work?

The substation receives electrical energy directly from generating stations through incoming power supply lines while it delivers electricity to the consumers through outgoing transmission lines. A substation which is near to the electrical power generation is also known as grid substation.

Why are substations important?

Substations receive high-voltage electricity from power stations or transmission lines and reduce the voltage to safer and usable levels for local distribution. Substations also play a crucial role in maintaining grid stability, managing power flow, and ensuring electrical safety and reliability.

What is a substation in a power plant?

In is substation, the power transmission can be done by using a transmission bus to transmission lines. This substation can also be a knock on the incoming power which is received by the generation plant. The received power can be used to supply power to the operation of apparatus in the plant.

What equipment is used in a substation?

To fulfill the function of a substation, they include a wide variety of equipment. Each of them will be explained in the next subsections. Power transformers are the most important equipment in an electrical substation. They are different from distribution transformers. They perform different functions. They are used to

What are the different types of power generating substations?

There are different types of power generating substations like thermal, atomic, and hydro-electric. Based on the availability of different resources, substations are building at different locations, but these locations may not be closer to load centers. The actual power utilization can be done by the load center.

What is the difference between a power station and a substation?

Power stations are typically located away from urban areas and are large-scale facilities designed specifically for electricity generation. A substation is a part of the electrical grid that acts as an intermediary between the power station (or transmission system) and the end-users (homes, businesses, industries).
