This paper presents a current orientation of the rotor doubly-fed motor speed control system of the simple vector control method, mainly through the detection of rotor current to control the rotor voltage and rotor current phase or reversed. When the double-fed speed, if the rotor and the rotor voltage vector vector always super-synchronous operation or sub-synchronous operation, we can guarantee the rotor side of the power factor is 1, which can reduce the capacity of the rotor side converter, reducing system costs. This paper introduces the basic principles of the system and composition, and finally gives the system simulation and experimental results
