高速永磁同步机型除具备上述双馈机型结构优点外，还有以下技术优点： PMSG system not only owns above characteristics as DFIG system, but also has technical advantage as follows:
感觉 advantage应该为复数
1.感觉应该为
Due to adopting full power converter with constant frequency output, a physical separation between the generator and grid will occur, as a result, votage droping in the grid will not affact the stator, which will ensure a smooth operation of the generator.
有点事，先改这些，后几句貌似都有问题

For PMSG system, besides the feature of DFIG system, it also comes with the following technical advantages:

1. The adoption of full power converter with consatant frequency output and the physical separation between generator and grid which ensures that the drop of grid voltage will not act directly on the stator of the generator assure the steady and smooth operation of the generator.

2. The use of sine wave pulse width modulation in full power converter would help achieve approximate voltage and current of standard sine wave, which not only greatly reduces the harmonic content but also improve the power quality.

3. Permanent magnet electricity generation technology can provide reactive power to the grid. Under the rated wind speed, permanent magnet generator can output electricity at a high efficiency. As a result, permanent magnet generator set will yield about 15%-20% more electricity per year than doubly-fed generator set does

4. Compared with Direct drive and Semi-direct drive generators, High-speed permanent magnet synchronous system is characterized in small size, light weight and low manufacturing and maintenance costs, which makes it more fit when applied to modern conditions of road transport and lifting. It is of  high promoting value and market competitiveness which is one of the directions of  development in high-power unit technology in the future.
