A novel method for real-time generating synchronous machine Ẽq waveforms and its application system

In this paper a novel method based on the rotor position sensor for real-time generating synchronous machine Etilde_q waveforms and the corresponding application system are proposed. The proposed application system can output a few channels of sine signals whose frequencies and phases are the same with those of the involved synchronous machine Etilde_q phasor. With the proposed application system, other application systems in the field can conveniently measure the rotor angle of the involved synchronous machine.
