Millennium Plan to pursue the dream of Xiong'an: State Grid's 3rd anniversary of serving Xiong'an's construction and development

The Baiyang Lake is surrounded by blue waters, and the thousand-year-old forest is sprouting green leaves. Spring has arrived as promised again. Xiong'an, a city of the future that carries the heavy responsibility of "a thousand-year plan and a national event", has ushered in its third spring.

Over the past three years, top-level designs such as the Outline of the Hebei Xiong'an New Area Planning and the Overall Plan of the Hebei Xiong'an New Area (2018-2035) have been released one after another. From planning and design to large-scale substantive construction, the strugglers have worked day and night and made great efforts, and the land of hope is full of vitality.

Over the past three years, under the "Xiongan New Area Power Grid Development Cooperation Framework Agreement" signed by State Grid Corporation of China and the Hebei Provincial Party Committee and Government, and guided by the "Hebei Xiongan New Area Power Special Plan", a full-coverage power supply guarantee planning system covering ultra-high voltage to low-voltage power grids has been gradually established; with the Zhangbei-Xiong'an 1,000 kV ultra-high voltage transmission and transformation project as the leader, a number of power grid projects such as the Xiongdong 500 kV transmission and transformation project, the Jucun 220 kV transmission and transformation project, the Beijing-Xiongan high-speed railway traction station supporting project, and the Hexi 110 kV transmission and transformation project have been started one after another, ushering in the era of full-voltage level construction of the Xiong'an power grid.

Planning is steady and steady

Carefully designing and drawing up a blueprint for the power grid

On March 4, seeing that the "Guidelines for Electricity Use of Power Customers in Xiongan New Area" was approved and officially issued by the Reform and Development Bureau of the Management Committee of Xiongan New Area of ​​Hebei Province, Tang Baofeng, a specialist at the Planning Center of the Xiongan New Area Power Supply Company, as one of the participants in the formulation of the guidelines, could not hide his excitement: "This is the first technical standard in Xiongan New Area that was compiled by an enterprise and issued in the name of the Xiongan New Area Management Committee." Tang Baofeng came to work in Xiongan New Area in October 2017. During the more than two years of participating in the power planning of Xiongan New Area, he has experienced such breakthroughs time and time again.

Xiongan New Area was established in 2017. State Grid Corporation of China has scientifically and prudently established world-leading goals for this future power grid: 100% clean power supply guarantee, 99.999% high reliability, and more than 50% of electric energy terminal consumption.

Tang Baofeng came to the new district at this time to depict the goal of building a world-class city with Chinese characteristics bit by bit in the planning map: "It is not feasible to copy the experience of any other city. Our daily work status is to discuss, deny, discuss, deny, discuss again, and deny again. It is common to revise any planning topic dozens of times."

Behind them is the more powerful planning and design team of State Grid Hebei Electric Power and State Grid Corporation of China, which gathers the wisdom of the entire network and the strength of all parties. Hundreds of first-class power experts in the company system have conducted intensive discussions, rigorous and solid research, and intense and pragmatic discussions. The power planning of Xiongan New Area has been continuously enriched through repeated collisions of ideas and has been improved day by day by absorbing advanced domestic and foreign experiences.

On May 21, 2018, the Hebei Provincial Government commissioned State Grid Hebei Electric Power to compile the "Hebei Xiong'an New Area Power Special Plan". In accordance with the requirements of the New Area Management Committee, State Grid Hebei Electric Power directly joined the New Area Planning Promotion Work Camp.

In June of that year, the "Special Electricity Plan for Xiong'an New Area, Hebei Province" passed the expert review of the New Area Management Committee at one time, and two months later, it was successfully reviewed by the Hebei Province Xiong'an New Area Planning and Construction Leading Group Meeting. In the end, the "Special Electricity Plan for Xiong'an New Area, Hebei Province" passed the review of the Xiong'an New Area Special Electricity Plan Expert Review Meeting and became the only one of the 26 special plans that was compiled by an enterprise.

While accelerating the preparation of special power plans, State Grid Hebei Electric Power also organized the preparation of power grid planning, power facility relocation plans and construction power supply guarantee plans for development projects such as the start-up area and Rongdong area, effectively supporting the implementation of special power plans. After the "Special Power Plan for Xiongan New Area, Hebei" was successfully reviewed, special plans for Rongdong area, start-up area and other areas were also successfully included in the regional control detailed plan.

Only by taking a longer-term view and drawing a more detailed blueprint can we live up to the heavy responsibility of "a millennium plan and a national affair."

In 2019, State Grid Hebei Electric Power compiled and completed the "Implementation Plan for the Construction of a World-Class Energy Internet in Xiongan New Area" based on the "Hebei Xiongan New Area Electricity Special Plan", and constructed the "1+9+N+1" power grid planning system for Xiongan New Area. From the overall to the local, from the present to the future, the construction path is clear and the power grid planning map is gradually transformed into a roadmap, project list and construction drawing.

It was also in this year that more and more projects were started in the new district, and the pace of planning implementation was getting faster and faster. For the unprecedented blueprint to become a reality, can every building, every underground corridor, every cable, and every piece of equipment in the city of the future be accurately connected?

On August 20, 2019, the Xiong'an New Area Power Planning and Design Service Center, jointly established by State Grid Corporation of China, Power Construction Corporation of China, and China Energy Construction Corporation, was unveiled and established. The office is located in the Xiong'an Design Center. This "central kitchen" for power grid planning, which concentrates superior forces, has to respond to the power requirements of the overall planning of the new area in the shortest time and at the fastest speed, and use technology to support each power plan to become a reality.

After the "Guidelines for Electricity Use by Electricity Users in Xiongan New Area" was officially issued, together with the "Technical Guidelines for Planning of Hebei Xiongan New Area (Electricity Volume)" which was previously included in the new area's planning and construction standards system, it formed a full-voltage power supply guarantee standard system covering both the grid side and the customer side, providing full-system standard support for the construction of a world-class energy Internet in Xiongan New Area.

Construction is in full swing

Pioneers build Xiong'an's quality

The planning is steady and the construction is in full swing. In 2019, Xiongan New Area gradually shifted from top-level planning design to large-scale substantive construction.

Following the construction schedule of the new district, State Grid Hebei Electric Power took the lead in completing the "one meeting and three letters" handling process for the construction of the Xiong'an New District. On February 2, 2019, the company obtained the first preliminary work letter for the new district's enterprise investment project approved by the new district management committee director's office meeting, and subsequently obtained the first design plan review opinion letter, the first enterprise investment project construction opinion registration letter, and the first approval reply document.

In March of the same year, the Zhangbei-Xiong'an 1,000 kV UHV AC project, a major channel for delivering clean energy to the new district, was first started; on September 17, the Jucun 220 kV and Hexi 110 kV power transmission and transformation projects, and the Beijing-Xiong'an high-speed railway 220 kV traction station supporting line project were fully started. In one year, the projects were carried out in multiple locations and simultaneously.

Build at an "accelerated" pace and do not relax quality control.

In the early simulations, once the Xiongan power grid started construction, it would face severe challenges of above-ground and underground, multi-disciplinary, and high-standard construction. In order to adapt to the unprecedented pace of construction, State Grid Hebei Electric Power started to develop the Xiongan power grid digital engineering management (EIM) platform in 2017, and conducted an in-depth trial of the platform in the Xiongan training project in 2019, and continuously revised and improved it based on more than a hundred comments received from actual applications.

As the Xiong'an power grid project kicked off construction, the iteratively upgraded EIM platform 2.0 quickly became a powerful tool for project construction management. The platform uses building information modeling and IoT technology, integrates 174 functions in 10 categories, including safety management, quality management, and progress management, and can carry 19 subcategories of IoT sensing devices in 7 categories, achieving two "visible" things: from feasibility study to completion, the whole process of digital management is visible; from the air to the underground, the construction site is visible from all angles.
