Its thought is to change the model of the asynchronous motor through the coordinate, make it become direct current motor model, divided the electric current vector of the stator into according to the weight of two pieces of direct current with directional magnetic field of the rotor and controls, realize magnetism coherent and torque solve lotus root control , in the hope of the control result of the direct current reaching machine.

其思想就是将异步电动机的模型通过坐标变化，使之成直流电动机模型，将定子电流矢量分解为按转子磁场定向的两个直流分量并分别加以控制，从而实现磁通和转矩的解藕控制，以期达到直流电机的控制效果。

Direct current is rejected: When the electricity owes and presses the trouble in the city, it will be too automatic to supply power disconnectedly at all that the direct current of connecting with end of direct current is rejected, direct current rejects and can provide the signal while discharging, if discharge to the terminal voltage, will change over to and prepare against the electricity to run in system, while closing to stopping discharging the voltage, the system will provide the signal of warning.

直流屏：在市电欠压或故障时，与直流端相联的直流屏就会自动毫无间断地供电，直流屏放电时会给出信号，如果放电至极限电压，系统就会转入备电运行，在接近终止放电电压时，系统将给出警示信号。

This thesis calculates emphases the excitor circult of AC excitor .but the calculate of excitor circult must solve two problem: how to caculate the output AC phasic potential, phasic electric current and the capacity of AC excitor basing on the main generator direct current excitating voltage and direct current excitation current ;how to caculate the armature feedback, power factor and required ampere-turn of AC exciter.
