Zhejiang's first 220kV semi-indoor prefabricated substation was successfully put into operation in Dongyang City

On August 13, Zhejiang Province's first 220kV half-indoor prefabricated substation-220kV Keats Substation was successfully put into operation in Dongyang City. This is also the first 220kV substation put into operation in Jinhua this year.

It is reported that the 220 kV Keats transformation has built two 240 MVA main transformers with 4 lines of 220 kV outlets and 8 lines of 110 kV outlets. It is one of the pilot projects for the steel frame structure of Zhejiang Electric Power Co., Ltd. It is also the fourth 220 kV substation within Dongyang City. Keats changed from the beginning of planning to consider the use of a half-indoor construction method. The benefits of this construction are that it can save land resources and reduce the impact of construction work on the environment. In addition, in order to enable substations to continuously adapt to new development requirements, Zhejiang Transmission and Transformation Company actively promotes modular construction and adopts full bolt connection technology. It can not only improve the quality and durability of the process, but also save the workload and the amount of welding, and realize the cost reduction, efficiency increase and environmental protection.

In recent years, with the rapid development of Dongyang City’s economic construction, the regional power grid has become increasingly saturated. At the same time, with the continuous innovation and upgrading of various social technologies, the requirements of urban development for power supply reliability and power quality are also increasing. Under the guidance of State Grid Jinhua Power Supply Company, State Grid Dongyang City Power Supply Company combined with Dongyang's development plan to actively promote the location planning of substations to ensure that the substation positioning is scientific and reasonable.

As a large-scale electric power project serving the "14th Five-Year Plan" city construction, the construction time of this project is tight and the task is heavy. In order to ensure the efficient advancement of engineering projects, all participating construction parties have adopted a new mechanism of party building work of "Party Building + Infrastructure" double promotion and double promotion in the construction, giving play to the battle fortress of grassroots party organizations and the exemplary vanguard role of party members. Focusing on the safe commissioning process of construction and construction, give full play to the functional advantages and highlights of each participating unit, continuously improve the cooperation mode of each unit, work together to build a multi-system team, and actively innovate and create excellence.

With the smooth commissioning of the 220kV Keats Transformation, the main grid of Dongyang City's power grid has been further improved, and the flexibility, reliability of the grid's operation mode, and the level of power grid intelligence have been greatly improved. Next, the municipal power supply company will accelerate the construction of various voltage grade projects within the Dongyang area, provide sufficient power for the development of Dongyang's industrial economy and the improvement of people's living standards, and continue to contribute to the construction of a new power system.
