On January 27, in Hoa Binh, the Vietnam Electricity Trade Union cooperated with EVN Repair Service Center (EVNPSC) and Hoa Binh Hydropower Company to launch an emulation competition to complete the replacement of the working wheel. unit 5 (H5)-Hoa Binh Hydropower Plant.
Unit H5 of Hoa Binh Hydropower Plant has been put into operation since 1992 and has been more than 30 years now. During minor repairs or major repairs, when inspecting the working condition of the wheels, the working group detected cavitation and defects, cracks in the wings; Especially from the end of 2021, this situation makes the unit operate in a high-risk mode and there is a risk of stopping the problem at any time.
Mr. Phan Dinh Hoa, Director of EVNPSC, said that the work of changing the impeller of unit H5 Hoa Binh Hydropower Plant is an important project to ensure safe, reliable and long-term operation. for the unit of Hoa Binh Hydropower Plant.
At the same time, this is the first project that EVN has implemented itself to replace, installation impeller, is an important milestone demonstrating the autonomy capacity in repair and maintenance of the Electricity of Vietnam for the renovation of large hydroelectric power units.

This project was assigned by EVN to EVN Repair Service Center to carry out the bidding for procurement and self-construction, installation, testing and commissioning. The company Hoabinh water electric consulting installation supervision and receiving management operate.
To ensure the completion of the work before May 30, 2023, EVNPSC has focused on researching and organizing many seminars to develop the most optimal construction plan.
The preparation for construction of EVNPSC is very detailed and meticulous, from the construction plan, the cost of equipment disassembly, the preparation of materials and equipment, the mobilization of experts, the plan of human resource arrangement.. . has received high consensus of experts and related units.

(Source: EVN)One month before the construction, EVNPSC sent a delegation to the Russian Federation to work directly with the manufacturer’s experts to discuss and agree on the optimal construction plans to shorten the repair schedule and project quality assurance.
The human resources selected by EVNPSC to construct the impeller are 56 core people with extensive experience who have directly performed supervision consultancy, construction, installation and repair of power plants across the country.
EVNPSC assigns the Director of the Center to directly be the Head of the Steering Committee to directly monitor and closely follow all developments at the construction site to have appropriate direction and adjustment plans to ensure smooth coordination between the units. , remove difficult obstacles to speed up the repair progress and quality; Head of Engineering and Safety Department of EVNPSC as the Project Manager to directly direct, operate and organize construction on the construction site; arrange two working teams to go to shifts continuously to ensure the progress and shorten the repair time.

The machine and the impeller replacement of the H5 unit face many challenges because this is the first project that EVN has implemented to replace the impeller by itself, with the nature of improving the efficiency of a large hydroelectric power unit.
The supervisory force is still thin, and at the same time, they have to supervise many other projects, while the other units are still operating normally.
However, with a sense of responsibility, the will to overcome difficulties and a spirit of creative labor coordination, Hoa Binh Hydropower Company commits to fully implement the contents of supervision and coordination process between the two countries. unit.
