wind power and photovoltaic energy situation supervision report

Not long ago, the state electricity supervisor will released "wind power and photovoltaic energy situation supervision report", "the report pointed out that by 2010, domestic first half because of wind power generators do not have access to the Internet to abandon the wind number of 27.76 billion kilowatt-hours, national nearly one-third of the fan in idling state. Is this phenomenon by wind power development planning, a because focused on resources planning, lack of specific wind-power sent out and wind power XiaoNa scheme, on the other hand also because of wind power construction and grid construction sync causes.

"With the wind power turbines industry fast development, the wind access issues are becoming increasingly prominent, current grid have restricted the development of wind power grid construction lag bottlenecks. Restrict the development of wind power has become one of the important factors." China¡¯s agricultural machinery industry association wind power equipment branch related researchers said.

Wind power grid difficult problem, director of research junwu technology grid Joe yuan said: "wind power grid problem encountered, primarily because wind-power resources distribution area and power load regional distance caused by the contractor, wind turbines manufacturers equipment. As junwu technology, make effort to dissolve the technical bottleneck for grid company and clients, providing better wind power management solutions, as well as help power system operation of higher quality and reliability of the grid superior performance, such as the wind generator can achieve wind and network voltage, power control technology of wind energy junwu management platform, can realize network fault when fan the stable operation of low voltage across ability."

As is known to all, the current wind generators market competition is becoming increasingly fierce, then fan equipment enterprises will depend on what occupy the market? Joe yuan thinks that future, junwu technology will through enlarging the r&d investment, research subdivision market demand, with continuous technology innovation developed meet different segments of the market demand of pluralism "power grid amiability" fan products, such as high altitude, low speed, low temperature, offshore wind power equipment for enterprises to exploit new profit growth point, these products without exception is the direct drive permanent magnet technology, has the excellence of grid performance, their grid friendly embodied in - low voltage across.

Junwu technology as a domestic initially adopt direct driving permanent magnet technology of wind power equipment manufacturers and wind power overall solutions provider, in direct driving permanent magnet technology of mastery and development has a wealth of experience, so far, there have been more than 3000 sets junwu technology direct driving permanent magnet units in global market parallel operation, highly recognized by the market and customers. Recently, the technology was also junwu at the Massachusetts institute of technology "technology review magazine was named" 2010 year worldwide the most innovative ability, think top 50 "enterprise junwu technology direct driving permanent magnet technology leading the new generation of fan technology trend.

Direct driving permanent magnet fan is considered a natural grid superiority, the main reason is: "direct driving small wind turbines permanent magnet technology generator with inherent in the whole power grid between converter equipment realized to output voltage and current regulation, with the characteristics of flexible transmission, therefore in the grid characteristics and realize low voltage across on a natural advantage. Junwu strict science and technology standardization production technology and process effectively ensure the bulk product low voltage across the ability", Joe yuan explained.

2010 April, jilin province bai cheng city areas due to bad weather, snow,

High-pressure line continuously happen alternate with short circuit, fault caused by the short time low voltage totaling 26 million kilowatts jilt the unit capacity. Technology of 5 million kilowatts junwu wind from the fault point line distance recently, voltage drops and the most serious, but all crew all realization fault through.

Since June 2010 in Germany through international authoritative testing institutions Windtest low voltage through testing, junwu technology direct driving permanent magnet 1.5mw units and 2010, August 5 success by China power science research institute of low voltage across the authoritative validation testing. Not long ago, and takes the lead in the domestic through scale conditions of low voltage through test, a move again confirm the permanent magnet product direct driving junwu technology of natural grid advantage, will vigorously promote technological comprehensive building "junwu grid friendly" products for clients, further discovery and create value.
