Xinhuili 110kV mobile intelligent substation

Introduction of Xinhuili Industrial Development Co., Ltd.

    Xinhuili Industrial Development Co., Ltd. was established in August 2011 with a registered capital of 210.1 million yuan and a registered address in Shenzhen Special Economic Zone, Guangdong. In the 11 years since its establishment, Xinhuili has grown from a technical enterprise in power policy research and mobile smart substation research and development to the current comprehensive power enterprise with power sales, power grid investment, substation investment, comprehensive energy investment and operation, and smart substation R & D and production. The "Regional Carbon Neutralization Overall Solution" model has been formed with the basic strategic pattern of new energy power generation + smart substation R & D and production + finance.

    The 110kV mobile intelligent substation (220kV, 110kV, and 35kV) developed by our group over the past 10 years fully realizes factory production, modular assembly, shielding electromagnetic radiation, occupies less land area, short construction period (put into use at any time), Strong mobility, less investment, flexible layout and other advantages. It can quickly solve power supply bottlenecks in development zones, help power supply companies quickly decompose power loads, and help large-scale infrastructure projects quickly solve power problems; Our group has invited a number of power experts to help develop the "Regional Comprehensive Energy Solution","Regional Carbon Neutralization Overall Solution","Enterprise Substation Asset Value-added and Value-preserved Management Model","110kV Mobile Substation Power Purchase and Sales Profit Model","110kV Mobile Substation Leasing Profit Model", the group has currently obtained intelligent substation test reports. It has formed a mass production scale of 110kV mobile smart substations and modular smart substations.

    Relying on its advanced technological advantages and advanced profit model, our group has successively cooperated with Gezhouba Group Electric Power Company, Huaneng Group Shandong Company, SDIC Electric Power Gansu, Jingneng Group Northwest Thermal Power Company, Northwest Electric Power Construction Company, Heilongjiang Electric Power Construction Company, Shanxi Electric Power Construction Company and many other energy central enterprises have signed strategic cooperation agreements.

    Relying on its technical advantages and team advantages in smart substations, our group signed a smart substation investment agreement with Jize County Government, Hebei Province in October 2017. In January 2018, we established a mixed-ownership power company with Zhengzhou East District Urban Investment Corporation, Henan Province. In June 2018, we helped Zhangjiakou City government completed the planning and preparation of the "Zhangjiakou Comprehensive Energy Solution". In October 2018, it officially signed a 23.2 billion yuan "Zhangjiakou Comprehensive Energy Investment Agreement" with the People's Government of Zhangjiakou City. At present, the group has successfully applied for the "Shangyiyuan Grid Load Storage Integration Project" and the "Shangyi County Coal-to-Electricity Project", successfully won the bid for the "Hebei Jize Incremental Distribution Network Pilot Investment Owner", and successfully applied for Shangyi County. The "Shangyi Wind Power Nearby Consumption Pilot Plan" has passed the demonstration of the Hebei Province Development and Reform Commission and was reported to the National Development and Reform Commission.

    The introduction of the central carbon neutrality policy has brought a once-in-a-lifetime development opportunity to our group's high-end intelligent substation production and manufacturing sector. Our group will follow the trend, adhere to the corporate spirit of serving the country with industry, and make positive contributions to the prosperity of China!

Introduction to mobile substation

Xinhuili vehicle-mounted mobile substation mainly consists of:
Zinc oxide lightning arresters, high-voltage switches (GIS or HGIS combination appliances), power transformers, medium-voltage switchgear, AC and DC integrated power systems, measurement, monitoring and protection devices are integrated and designed into high-tech mobile vehicles;

It has the advantages of flexible combination, fast installation, intelligent security monitoring system, intelligent operation and maintenance system, intelligent control system, small size, flexible site selection, convenient operation and use, small investment, quick results, and exemption from land acquisition procedures.

The concept of "mobility" of the substation is based on the proposal and guidance of the former "Second Artillery Corps" chief, and with reference to the concept of a missile launch vehicle, the entire substation is integrated and designed on a high-tech mobile vehicle. It can be quickly maneuvered, transferred quickly, and put into operation. The concept of "intelligence" is reflected through the intelligence of the secondary plan. The mobile substation automation system is integrated into a three-layer equipment and a secondary network structure. Realize substation informatization, automation and interactivity.

The primary side of the 110KV mobile substation put into operation in the power grid in recent years has a rated voltage level of 40.5-126kV, and a capacity of mostly 20 - 50MVA, which has reached the capacity and voltage level of conventional substation in medium-sized township power grids.

Mobile substation

• Main applications: New investment companies in the development zone have electricity problems, quickly and effectively respond to natural disasters or emergency repairs in substations, and quickly restore power supply to minimize disaster losses; temporary construction power supply for large-scale infrastructure projects.
• Main features：
  • The overall structure of the product is compact,highly mobile and convenient to transport;
  • Products adopt standardized/modular, integrated design and production;
  • Products involving switchgear, transformers, etc. are all designed and optimized by mature products, with guaranteed reliability and intelligence.

Advantages of Xinhuili on-board mobile substation

1. It can help the power supply company quickly decompose the substation load pressure, reduce the investment pressure of the power supply company, reduce the compliance pressure of the power supply company's 10KV distribution network, reduce line loss, and reduce the impact of frequent start-up of large mechanical equipment in infrastructure projects on the 10kV distribution network.

2. It can quickly solve the electricity problem of large-scale infrastructure projects;

3. Highly intelligent (equipped with intelligent security monitoring system and intelligent operation and maintenance system);

4. Less investment (leasing model);

5. Reduce land acquisition procedures;

6. It can be used as a backup substation for emergency repairs to buy time for emergency repairs;

7. It can help development parks quickly solve power supply bottlenecks.

The voltage class of vehicle-mounted mobile substation is 10kV~220kV, and the rated capacity ranges from 100kVA to 40MVA.
The entire station is generally composed of transformer cars and distribution cars. The number can be flexibly combined with two or more cars. In various forms, in addition to typical parameters, it can also be customized according to user needs.

Advantages of mobile substations

• Low cost, flexible and fast operation
• Reduce investment in temporary power supply for construction
• Exemption from land expropriation procedures, no basic installation
• Reduce the load pressure of the power supply company's 10KV distribution network

Dynamic ring system monitoring

It mainly refers to the substation with network communication as the core, including station short video, environmental monitoring, fire protection, access control, SF monitoring, cable temperature monitoring, safety guard and other related equipment linkage.

And according to the on-site needs of the intelligent substation, automatic closed-loop control and alarms can be completed, such as automatic start/off air conditioning, automatic start/off fan, automatic start/off switch system, etc.

Send the above information to the monitoring center.
