Energization of the first 220kV GIS substation project in Danang City

01/10/2024 08:27:36

At 20:37 on September 30^th 2024, the Central Power Projects Management Board (CPMB), in coordination with relevant units, successfully energized the 220kV Hai Chau substation and 220kV Hoa Khanh – Hai Chau transmission line project. This is the first GIS substation project of Danang City to be completed and energized.

The 220kV Hai Chau substation and 220kV Hoa Khanh – Hai Chau transmission line project was implemented in Danang City, invested by National Power Transmission Corporation (EVNNPT), managed by CPMB, and operated by Power Transmission Company 2. Power Engineering Consulting Joint Stock Company 4 (EVNPECC4) is the engineering consultant for the project. Accordingly, Substation Engineering Centre - EVNPECC4 applied BIM model for engineering the project.

The project involves constructing a new 220/110/22kV GIS substation with an installed capacity of 2x250MVA, with one 250MVA transformer installed in this phase. It also includes the construction of 220kV double-circuit Hoa Khanh - Hai Chau transmission line, which is nearly 10 km long. Of this, the underground cable section is over 7.3 km long (it is also the first underground cable line in Danang City) and the overhead line section is nearly 2.6 km long. Additionally, a 22kV underground cable (121m long) is built to supply power to the 220kV Hai Chau substation.

During implementation, the project faced numerous difficulties and obstacles related to land clearance and compensation, especially for the 220kV Hai Chau substation due to a business entity's delay in handing over the land for construction. The overhead and underground 220kV transmission lines also encountered difficulties related to compensation plans and land prices. Moreover, the project faced obstacles related to the intersection of transportation routes, leading to significant delays in land handover. The construction process was also hindered by the pandemic, natural disasters such as storms, and prolonged floods, …

However, thanks to the close direction of National Power Transmission Corporation’s leaders, the support of local authorities and people in the project areas, as well as the efforts of CPMB and participating units, the project was completed on schedule.

The completion of the project helps to enhance the power supply capacity, meet the load growth demand of Danang City, and strengthen the interconnection, improve the safety, reliability, stability in operation, and power quality. The project helps to meet the N-1 criterion and reduce power losses of the regional power system.

*Previously, the investor-level acceptance council had a meeting and agreed to energize the project*

It is known that GIS substations, which include gas-insulated switchgear (GIS) using SF6 gas, are an advanced technology that is widely applied in many countries worldwide. The advantages of GIS substations include saving space, reducing land and equipment costs, ensuring safe operation, and extending maintenance intervals.
