Heilongjiang Huanggou pumped storage power station unit was fully put into operation for power generation

On June 29, Unit 4 of the State Grid Xinyuan Heilongjiang Huanggou Pumped Storage Power Station was officially put into commercial operation, marking the first pumped storage power station in Heilongjiang Province that was fully put into operation
.
The commissioning of the power station is another landmark achievement of the State Grid Corporation of China in actively serving the goal of carbon peak and carbon neutrality, promoting the construction of a new power system, and accelerating the construction of pumped storage, which will effectively ensure the safe and stable operation of the Northeast Power Grid and boost local economic and social development
.

Huanggou Pumped Storage Power Station is located in Sandaohezi Town, Hailin City, Mudanjiang, with a total investment of 5.
803 billion yuan, the hub project consists of upper reservoir, lower reservoir, waterway system, underground workshop and ground switch station, with a total installed capacity of 1.
2 million kilowatts, and four single-unit units with a capacity of 300,000 kilowatts are installed, which are connected to the northeast power grid
through 500 kV lines.
The construction of the power station began in May 2014 and will provide more than 3,000
local jobs during the construction period.
The full-scale commissioning of power stations can stimulate the development of upstream and downstream industries, boost the development of local culture and tourism, and play an important role
in promoting local economic and social development, consolidating the achievements of poverty alleviation, and helping rural revitalization.

Since the first unit was put into operation at the end of 2021, the three units that have been put into operation at the Huanggou Pumped Storage Power Station have operated stably
.
Up to now, the average start-up success rate of the unit is 99.
8%, the cumulative power generation is 524 times, the pumping time is 466 times, the power generation is 536 million kWh, and the pumped power is 682 million kWh, undertaking the power preservation tasks of the Northeast Power Grid to meet peak summer, peak winter and important festivals, and give full play to the functions
of peak shaving, frequency regulation, phase modulation, energy storage and system backup.

Up to now, the installed capacity of wind power in Northeast Power Grid has reached 47.
25 million kilowatts, accounting for 26.
3%.

The Huanggou pumped storage power station can greatly alleviate the pressure of new energy consumption and inter-provincial power transmission pressure in the Northeast Power Grid, and can promote the consumption of clean energy by more than 2.
4 billion kilowatt-hours per year, save 200,000 tons of standard coal and reduce 520,000
tons of carbon dioxide.

The Aragou pumped storage power station is located in the alpine region and the construction conditions are complicated
.
Project builders explore and implement the project management and control mode of "five-in-one, harmonious co-construction" of owner, design, supervision, construction and locality, adopt underwater construction technology of hydraulic buildings, and strengthen the insulation of finished concrete products and the protection
of outdoor equipment and facilities.
The engineering construction realized technological innovation, and for the first time, the stator winding type of four-branch power generation motor with the advantages of small number of wire rods, short core length and good electromagnetic parameters was adopted; The building information modeling (BIM) technology is used to establish a digital 3D model of the underground plant, and the 3D visual simulation of the cable laying of the whole plant is implemented to improve the quality and efficiency
of the laying.

The power station is located in the northeast black soil area, and the State Grid Xinyuan Mudanjiang Pumped Storage Company strictly implements the measures of water protection measures and the main project design, construction and use at the same time; Organize special teams to collect and store humus; Signed an agreement with the local forestry department to cultivate rare tree species in neighboring forest farms to achieve harmonious coexistence
between power station construction and nature.
