Prominent advantage
The leading products of Swiss Electric are 1.5MW, 2.0MW, 3.0MW, 6.0MW and the above model permanent magnet direct-driving wind turbines. Swiss Electric has achieved two world highest honors certified by both the Germanisher Lloyd and the CCS: the key indicators of wind turbines are in the world leading level; the only 2.0MW permanent magnet direct-driving wind turbines who obtained the GL Type Certificate(2010 version) all over the world.

Four criterions
Swiss Electric is the first to present the simple way to determine Superior or Inferior of the wind turbines,”One high One low”
“One high” means that in the condition of the same type, the same wind farm and the same period, the power generation is higher than that of any other world famous wind turbines
“One low” means that in the condition of the same type, the same wind farm and the same period, the O&M cost is lower than that of any other world famous wind turbines.

Swiss Electric is the first to present the simple way to determine Superior or Inferior of the wind turbines,”One high One low”

“One high” means that in the condition of the same type, the same wind farm and the same period, the power generation is higher than that of any other world famous wind turbines, and “One low” means that in the condition of the same type, the same wind farm and the same period, the O&M cost is lower than that of any other world famous wind turbines.

1.There are three evidences for the power generation higher than that of any other world famous wind turbines in the same period:
1)The power curve identified by GL type certification approved by the top international certification organization, Germanischer Lloyd.
2)The authorized data tested by China Electric Power Science Institute.
3)The real-time operation data in our wind farms.

Technical Route Comparison

Technology
     
Definition
     
Introduction
     
PMDD wind turbine
     
The Rotor rotates to drive the PMDD synchronous generator directly
     
High reliability, high generating efficiency, low maintenance cost, Good power quality, and excellent LVRT performance.
     
Electro-magnetic DD wind turbine The Rotor rotates to drive the Electro-magnetic DD synchronous generator directly
     
The generator volume is too bigger to transport. Electro-magnet needs extra power supply and it is complicated. It must consume electricity from the grid when connecting to the grid. So, the reliability, efficiency and maintenance cost all is worse than PMDD wind turbine.
     
Double-fed wind turbine   
     
The Rotor rotates to drive the gearbox, and the gearbox speed up to drive double-fed asynchronous generator
     
Low reliability, low generating efficiency. The gearbox is easily worn and oil leaked easily, so the maintenance cost is higher and the failure rate is higher. The gearbox increases driving links, and decreases the efficiency. The noise is bigger.

"Three lows and one high" technology achievements "one high and one low" advantage

1. Low cut-in wind speed
Electromagnetic parameter design, generator structure design and structural mechanics distribution etc these advantages of Swiss Electric permanent magnet direct-driving wind generator make the start resistance moment of the generator lower and the efficiency higher than similar products at home and abroad. The electricity can be normally generated when the wind speed is 1.8m/s.

2.Low rated wind speed
The control strategy of Swiss Electric wind turbines is determined independently by our company, and the control system software compiled independently by our company. Therefore, each system of our wind turbines can enter the optimal working condition and play the best efficiency.So the wind turbines of SSE can achieve the full power generation in the lower wind speed.

3.High availability
The wind turbines adopt permanent magnet direct-driving structure, as wind turbine has no gearbox, decreases the driving stages, and completely eliminates the shortcomings of high failure rate existing in gearbox of the traditional wind turbines. Because of advanced structure design, the protection level of the wind turbines reaches higher and it can be operated stably under sandy storm and salty fog these kinds of severe environment.

4.Low O&M cost
Swiss Electric adopts PMDD structure without gearbox, so, there is no common easy breakdown existing in the gear and the oil leakage existing in gearbox of the traditional wind tubines, and reduces the O&M cost greatly (66% lower than double-fed wind turbines). Meanwhile, Swiss Electric wind turbines adopt the best composite cooling method, and the cooling performance is superior, which secure the stable operation of wind tubines, and reduce the maintenance cost.
