摘要
提出了一种新的风力发电技术。该技术是处于“恒速恒频”和“变速恒频”之间,风力机可以在几个叶轮转速点输出频率恒定的电能,相对恒速恒频风力机只在一个转速点输出所要求的恒定频率电能有较大的进步。该技术的风能利用率相对较高、经济实用、简单可靠。
A newtechnology is considered more efficient than the fixed-speed, constant-frequency wind power generation system and more economic than the variable-speed, constant-frequency wind p economic and simple wind energy technology is presented, this ower generation system. The turbine with this technology can generate constant-frequency electrical power among some rotor speeds of blades.
