The thyristor and stator winding have different topology architecture when the inductionmotor is controlled by the thyristor. Based on the fault characteristics of the inductionmotor, the current through the thyristor and the stator winding are studied when theshort-circuit or open-phase fault is occurred. The reasonable protection method based onthe different topology architecture is given in the thesis, and the induction motor and theover-current of the thyristor are reliably protected.

由于对断相运行给电机造成的危害认识不同，因此在对电机实行断相保护时产生了两种不同的意见：认为断相给电机造成过热损坏的观点要对电机实行过热保护或过流反时限特性保护，由此产生了热继电器方案、热敏电阻方案、断相过流延时保护方案以及其他一些方案；认为断相给电机绕组造成高压反电势击穿的观点，对断相采取瞬时动作保护方案，于是一些电子式保护器问世。

The following functions can be realized: Measuerment:the effective values of three phase current and voltage, power frequency, active power, reactive power, power factor etc. Motor control: direct starting, converse starting, star and triangle starting, self-starting. Protection:thermal overload protection, current leakage protection, open-phase protection, three-phase unbalance protection, over voltage protection, loss voltage protection, low load protection and fault warning and fault dates memory. Communication: communication of the computer in control room and the microcomputer monitor in the spots is realized by the interface of RS-485. The motor is not only controlled in the spots but also in control room. The dates, information and some functions are shared by the spots and control room too.
