2051单片机在发电机转速监控装置中的应用 - A high - speed generator is much different from a low - speed one not only on the mechanical aspect but also on the electrical - magnetic aspect . the main content of this paper are focused on the followings : first of all , a series of problems caused by the high speed are researched and the relative solutions are given out about the stator , the research focuses on stator losses , winding type , cooling system and so on
高速发电机转速很高，无论在机械性能方面，还是电磁性能方面都与低速电机有较大不同，本文主要内容就是围绕高速永磁发电机的设计特点从以下几个方面展开的：首先，对高速电机因高转速引起的一系列问题进行了研究，提出了解决相关问题的措施。 - In this paper , several scheme of vscf is compared firstly , of which gets doubly - fed generating mode . doubly - fed vscf wind power generating system uses a doubly - fed induction generator , which rotate speed can be able to change with wind turbine , and it ensures a constant - frequency output , by controlling the frequency of current input into rotor windings . in vector trans control system , the control of stator active power and the control of stator reactive power can be essentially decoupled , and the former is via torque component and the latter is via exciting component of stator current
本文首先比较了几种变速恒频方案，从中选择了双馈式变速恒频方案；它运用双馈电机的工作原理，允许发电机转速变化，而在电机转子侧接入低频励磁电流，通过控制该电流的频率，保证双馈电机定子输出的频率恒定；再结合矢量控制技术，通过调节转子电流来控制定子电流的转矩分量和励磁分量，相应独立地控制发电机输出的有功功率和无功功率。
