The Qianjiang River has great potential to build the world's largest tidal power generating unit

August waves came slamming, and the first few feet touched the hill.

Recently, Qianjiang Chao, the largest in the past nine years, has attracted tens of thousands of people for disputes. But you might have thought that there is much energy behind this tide. Tidal power generation, as a kind of clean energy, is not only the attention of government departments but also a new business opportunity for equipment manufacturing enterprises to enter strategic emerging industries.

Tidal energy resources in Zhejiang account for 40% of the national total

“Zhejiang is one of the provinces with the most abundant tidal energy resources in China.” According to a report from Zhejiang Institute of Hydraulics and Estuary Research, according to statistics of census results in the 1980s, the installed capacity of tidal energy resources that Zhejiang can develop is 8.798 million kilowatts. About 40% of the national total. The newly released "Zhejiang Marine Economic Development Demonstration Zone Plan" clearly states that Zhejiang Province will comprehensively develop clean energy including tidal energy.

Take the Qianjiang Tidal Water in Hangzhou Bay, because of the enormous energy released by the tidal wave crushing, the flooding tide is advancing quickly. Generally, when tides reach 5 to 7 meters per second, the maximum is 12 meters per second. . According to estimates, a huge surge of pressure can reach 7 tons per square meter.

However, tidal power generation requires higher natural conditions. Tidal power generation is the use of favorable terrain such as bays and estuaries to build water embankments and form reservoirs to accumulate seawater in great quantities, and build hydroelectric power plants in dams or dams to generate electricity through hydroelectric generating units. “In the 1980s, there was a climax of tidal energy utilization in the coastal areas of Zhejiang.” According to experts from the Zhejiang Provincial Energy Bureau, the Chaozhou-Jiangxi Chaoshan Experimental Power Station built at that time still ranked first in the country. From the power generation principle, there is no fundamental difference between tidal power generation and hydroelectric power generation, but tidal energy still has many special features. “Tidal power plants use seawater as the working medium, and the equipment is immersed in seawater all year round. Special consideration is needed to prevent the corrosion of equipment and prevent the attachment of marine organisms.”

Hangzhou to build hydropower and tidal energy equipment manufacturing base

“Tidal energy, as a renewable energy source, has become an important part of new energy in the strategic emerging industry planning of Hangzhou.” The person in charge of the Division of Ocean Affairs of the Municipal Development and Reform Commission introduced that in recent days, Hangzhou has officially issued opinions on accelerating the development of the marine economy. . The development of advantageous industries in the marine economy and support for the development of emerging industries in the ocean have become a key point for the development of the marine economy in Hangzhou. The comments specifically mentioned the production of marine clean energy equipment: “Promoting R&D and manufacturing of wind turbines and key components for wind power generation, building offshore wind energy equipment bases in Hangzhou; strengthening large and medium-sized hydroelectric power generation equipment and tidal energy equipment, and core facilities, etc. To develop, design, manufacture, install and service hydropower and tidal energy equipment manufacturing bases.”

“Hangzhou City has established guidance and support funds for marine economic development projects.” According to a person from the Municipal Development and Reform Commission, Zhefu Hydropower won the special fund award for winning the bid for the Korean Chaoshan Power Station.

Hange achieves zero breakthrough in export of large-scale tide units

Although Hangzhou does not rely on the sea, this does not prevent Hangzhou companies from gaining a share of the ocean economy. In the sea-related equipment manufacturing industry, many Hangzhou-based enterprises have rushed ahead of the industry. Recently, another Jiebao report came: South Korea's Shihua Hu Power Station, which was built by Hangzhou Fuchunjiang Hydropower Equipment Co., Ltd., which was involved in generating units, was put into operation last month. This is currently the largest tidal power station in the world. After it is put into operation, it can provide environmentally friendly power generated by the use of tidal water to cities with a population of 500,000.

Zhefu Hydropower, as the only domestic manufacturer, provided 10 sets of the most technologically advanced and important components for this power station unit. Zhefu Hydropower Co., Ltd. has tackled cutting-edge technical issues in the field of tidal power generators and has taken the lead in achieving breakthroughs in the world's leading tidal power design and manufacturing core technologies. “This project has achieved a breakthrough in the export of China's large-scale tidal turbines, and it has also taken an important step in the domesticization of tidal power generators in China.” According to industry evaluations, “This also reflects the fact that Hangzhou-based enterprises are involved in the sea-related industries and new energy fields. The rapid development and the ability to seize the initiative."
