Jin Zhai, river bank Mongolia, tianchi, formally began pumped storage power station

In June 2015, Jin Zhai in anhui, shandong, henan, river bank Mongolia tianchi pumped storage power station (hereinafter referred to as the \"smoke Jin Zhai, river bank Mongolia, tianchi storage\") construction mobilization meeting held in Beijing. River bank Mongolia, Jin Zhai, tianchi storage is promoting the construction of uhv grid state grid corporation of major projects, services in the development of clean energy, starts the three pumped storage power station at the same time, marked the pumped-storage power station in our country has entered a new stage to speed up the development.

It is understood that Jin Zhai, river bank Mongolia, tianchi storage with a total investment of 21.7 billion yuan, a total installed capacity of 3.6 million kilowatts, scheduled to be completed in 2021, all the production. Regarding luan, anhui Jin Zhai pumped storage power station is located in anhui province Jin Zhai county, the installed capacity of 1.2 million kilowatts, install 4 units of 300000 mw reversible hydro-generator units, access to a 500 kv voltage, anhui power grid project investment of 7.5 billion yuan. Shandong river bank Mongolia in the pumped storage power station which is located in shandong province Interpretation, fei county, installed capacity of 1.2 million kilowatts, install 4 units of 300000 mw reversible hydro-generator units, access to a 500 kv voltage, shandong power grid project investment of 7.4 billion yuan. Henan tianchi pumped storage power station is located in the river South province nanyang nanzhao, installed capacity of 1.2 million kilowatts, install 4 units of 300000 mw reversible hydro-generator units, access to a 500 kv voltage of henan power grid, project investment of 6.8 billion yuan.

Pumped-storage power station with the advantages of flexible start, adjust speed, is a mature technology, reliable operation and more economic load power and energy storage power. Pumped storage power station in the system mainly undertake the peak shaving and valley filling, frequency modulation, phase modulation, and emergency backup task. Pumped-storage power station in the load is low, through the pumping system difficult to consumption of electrical energy is converted to potential energy; At the peak load or the system needs, by generating electricity can converts the potential energy system need. Pumped storage power plant can use its energy storage effect, achieve peak peel and effectively reduces the outside calls and new energy output fluctuations, improve the stability of the system operation, improve the ability of the safe and stable operation of power grid, improve the level of economical operation of power systems, to achieve optimum overall social resource allocation.

Together, through the pumped storage and uhv grid interaction, Jin Zhai, river bank Mongolia, tianchi storage is completed, will help to improve the operation characteristics of uhv power grid, better accept outside calls, improve the \"three north\" area clean energy given ability. Second, can improve the power system safety and reliability, full play in the uhv grid \"stabilizer\" and \"regulator\", \"balancer\" role. In addition, the optimization of the structure of the local power supply, the relieve system System load frequency control pressure, supporting local new energy development, working with local nuclear power development. Jin Zhai, river bank Mongolia, tianchi storage will help improve the overall system efficiency, promote energy conservation and emissions reduction and prevention and control of atmospheric pollution.

At present, the national electricity grid in pumped storage power station installed capacity of 16.46 million kilowatts, construction scale of 12.66 million kilowatts. But the national accounts for pumped storage power generation total installed is still less than 2%, lower than the 5% average in developed countries. \"Much starker choices-and graver consequences-in\" period, China will continue to accelerate the construction of uhv grid and clean energy will continue to rapid development, is expected in 2020, Chinas wind power, solar power generation capacity will reach 240 million kw, 100 million kw, the inevitable requirement system adjustment ability and enhance security measure of synchronization. To speed up the construction of pumped storage power station in the protection of electrical energy security, promote clean energy given, improving energy efficiency, governance, haze, the economy, the service peoples livelihood more highlights the strategic significance and global influence.
