论文第二章从异步电机的基本数学模型入手，介绍了一种基于转子磁场定向的带电流内环控制的电压型逆变器输出闭环矢量控制结构，在理论上证明了该模型可省略电压前馈解耦环节，采用f240dsp芯片构建的带速度传感器实验系统验证了其定子电流励磁分量和转矩分量有良好的解耦控制特性。 | | 3. | 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。 | | 4. | This strategy has many advantages : solving the problems that the system is unsteady under super - synchronization ; improving power factor of stator ( it is unity relative to that of rotor ) ; no rotor position sensor and no initial position measurement , easily building up doubly fed speed adjustment system with speed sensorless because adjusting speed is taken in the rotor coordinate and rotor current vector fixing is implemented
该方案由于引入了定子电流励磁分量的闭环控制，使系统同时具有转速和励磁调节两个调节通道，具有如下优点：一、解决了超同步工作工况不稳定的问题；二、提高了定子侧的功率因数(与转子侧功率因数为1相比) 。三、由于速度调节在转子坐标系下进行，并以转子电流矢量定向，所以无须转子位置传感器，也不用检测初始位置，易于组成无速度传感器双馈调速系统。 | | 5. | The approximation analysis result of band dipole model is obtained on the basis of the theory of mfl . the electromagnetic distribution feature of the defect in the steel panel is studied by means of simulation . the leakage magnetic distribution of the two defects and four defects plural and the defects in the column differently in the width are also assayed . conclusions that factors affecting flaw magnetic leakage to the panel also affect the column and magnetic leakage bx should be the feature of the flaw identification to several flaws are drawn
