What is a distribution GIS? What does GIS refer to in a power system?

With the establishment of China's socialist market economy, the electricity market has gradually taken shape. In all aspects of power generation, transmission, distribution and marketing of power production, power companies have felt strong pressure from the market. In order to survive and develop in the fierce market competition, power supply enterprises can only rely on improving their competitiveness; Based on first-class technology and first-class talents, we provide users with first-class power supply services through first-class management.

One of the most important points is to accelerate the pace of power grid transformation through scientific and technological progress, improve the level of management and decision-making, and create greater economic benefits. With the strong support of Hubei Provincial Electric Power Company, since the end of 1998, Wuhan Power Supply Bureau and Shenzhen Yadu Graphics Software Co., Ltd. have jointly developed and developed it"Wuhan Power Supply Bureau AM FM GIS"System. This is the country's first distributed structure, the largest distribution GIS system.

Now you can know what a power distribution GIS is.

GIS in the power system: connect the power equipment, substations, transmission and distribution networks, power users and power loads of power enterprises to form a comprehensive production management information system of power informatization. The GIS platform of power grid is an important part of the information construction of power grid enterprises, and its core function is to provide basic data and services for various specialties of power grid enterprises.

The power equipment information, power grid operation status information, power technology information, production management information, and power market information provided are unified with the natural environment information set such as mountains, rivers, terrain, towns, roads, meteorology, hydrology, geology, and resources.

Through GIS, you can query relevant data, **, images, maps, technical information, management knowledge, etc.

The GIS platform adopts computer graphics technology, database technology, network technology and geographic information processing technology that are synchronized with the world.

GIS technology supports a variety of database management systems, runs a variety of programming languages and development tools; Support various operating system platforms; Provide standardized interfaces for various application systems, such as SCADA, EMS, CRM, ERP, MIS, OA, etc.; Can be embedded in a non-dedicated programming environment.

The in-depth application of the power grid GIS platform has promoted the standardized management of power grid equipment, power grid data sharing and business integration, and improved the life cycle management of power grid assets and the lean management level of power grid equipment.

The system design adopts the latest technology, supports remote data and drawing query, and uses the powerful chart output function provided by the system to directly print maps, statistical reports, various data, etc.

gis（geography information

system) is based on the geospatial database, with the support of computer software and hardware, the collection, input, management, query, analysis, simulation and display of space-related data, and the use of spatial model analysis methods to provide a variety of spatial and dynamic information in a timely manner, for geographic research and decision-making services and the establishment of a computer technology system.

With the development needs of power security and the development of the ubiquitous Internet of Things, the auxiliary safety management and control platform of Hangzhou Jingwei 3D GIS-based substation came into being, providing ultra-large-scale modeling and operation capabilities at the provincial, prefectural, county and district levels to escort the safe operation of electric power.

GIS in substations is gas-insulated combined electrical equipment.

GIS Electric is a gas insulated switchgear in Jianshou Bend, also known as sulfur hexafluoride enclosed combined electrical appliances, using sulfur hexafluoride gas with good insulation performance as insulation and arc extinguishing medium, so it can greatly reduce the volume of the substation and achieve miniaturization.

The role of the substation Qincha station:

The power generated by the generator is boosted and fed into the high-voltage power grid, and the voltage and current of the power are transformed, concentrated and distributed. The role of the substation in the power system is to transmit the electric energy emitted by the power plant to the long-distance power consumption area through voltage conversion, and then the power energy sent by the power generation is converted to the voltage conversion and electric energy distribution.

Main substation equipment:

There are power distribution equipment, power transformers, control equipment, protection automatic devices, communication facilities, compensation devices, etc.

The transformer should be protected from direct lightning strikes by lightning rods or wires, and the transformer should be protected from lightning intrusion waves by using valve-type arresters. <>

It is a gas-insulated metal-enclosed switchgear.

GIS equipment refers to gas-insulated metal-enclosed switchgear, which is composed of circuit breakers, disconnectors, grounding switches, transformers, lightning arresters, busbars, connectors and outgoing terminals. GIS is widely used not only in the field of high voltage and ultra-high voltage, but also in the field of ultra-high voltage. Compared to conventional open substations.

Electric power GIS is a comprehensive production management information system that connects the power equipment, substations, transmission and distribution networks, power users and power loads of power enterprises to form a comprehensive information system for production management of power informatization.

It provides information on power equipment, production management, and electricity markets, as well as information on the natural environment such as mountains, rivers, and resources, in a unified system. Through GIS, you can query relevant data, images, maps, technical information, management knowledge, etc.

Necessity for the development of GIS:

In the power system, energy resources such as transmission networks, distribution networks, power plants and equipment, users and loads, coal, water, geothermal, and wind power are all distributed according to geography; Geographical maps showing various types of electrical equipment and lines are useful tools used by the power sector to manage and maintain electrical equipment and to find and troubleshoot faults.

At the beginning, these map systems were completely set up manually, that is, after obtaining a map with a certain accuracy from the administrative department, the power department marked the symbols of various power equipment and lines, and established the technical documents of the equipment and lines accordingly. In this way, not only a large amount of human resources are consumed, but also the data update cycle is long, which can not fully meet the requirements of power system operation.

In order to meet the evolving requirements, the power sector has established a number of power graphic information systems, and began to use computers as carriers to transmit graphic information and equipment information.

GIS is called gas-insulated metal-enclosed switchgear in the power grid industry, GIS is composed of circuit breakers, disconnectors, grounding switches, transformers, lightning arresters, busbars, connectors and outgoing terminals, etc., these equipment or components are all enclosed in the metal grounding shell, and are filled with SF6 insulating gas with a certain pressure inside, so it is also called SF6 fully enclosed combined electrical appliances.
