rotor voltage
Examples
- After the detail account of the performance of the variable speed system , we know that if the machine carries out completely speed control , it must use the vector decoupling of the mt voltage
对双馈电机的调速性能进行了详细讨论，得知双馈电机要完全进行调速必须实现mt轴转子电压矢量的完全解耦。 - Therefore . the unit rotor power factor can be implemented . in the second scheme , the stator power factor can be improved by adjusting the angle between rotor voltage and rotor magnetic linkage
在第二种控制方案中，通过控制转子电压与转子磁链保持一定的角度，通过改变转子电压与转子磁链的夹角，即可改变定子侧功率因数。 - It proves that the capability of wind generator is determined to slip , rotor voltage and angle between rotor voltage and stator voltage , and investigates the control model based on the stator field - oriented vector control
文中还分析了双馈型风力发电机的转矩特性和稳态特性，证明了发电机的性能由转差率、转子电压和定转子电压间的相位角差决定的。 - Based on the analysis of the control theory of the dtc of doubly fed induction machines , in this paper , two control schemes are proposed : the least mode of rotor current and the stator power factor adjustable mode . in the first control scheme , we may make the rotor voltage the same or opposite phase with the rotor current by throwing suitable rotor voltage vector
在第一种控制方案中，通过施加转子电压矢量，使转子电流与转子磁链垂直，转子励磁全靠定子电流，即可保证转子电流和转子电压同相或反相，从而实现了转子侧功率因数为1 ，可减小转子侧变频器的容量。 - The contributions done are as follows : according to the mathematical model of doubly fed motor and the theory of vector control , a unit power factor of rotor control scheme is proposed . in the doubly fed adjustment system , in order to control magnetic torque of motor this scheme is designed by controlling the reverse direction between rotor voltage and current to keep the vertical direction between rotor current and flux . it is known from theoretical analysis that for partly decoupling this scheme is only effective under sub - synchronization speed , but not control the system and obtain steady state since speed adjustment system ca n ' t adjust the magnitude of rotor flux under sup - synchronization
而传统的无速度传感器双馈调速矢量控制系统，由于采用磁链定向方法，在同步速附近存在较大的工作死区，针对上述问题，本文做了如下的研究工作：本文从双馈电机的数学模型出发，根据矢量控制的基本原理，提出了一种转子侧功率因数为1的双馈电机矢量控制方案的设想，即在双馈调速时采用转子电流定向的方法，并控制外加转子电压与转子电流始终反相，以保持了转子电流与转子磁链矢量垂直，通过控制转子电流的大小来达到控制电机电磁转矩的要求。
