| Abstract: | The paper,proceeding from the protection configuration of auxiliary motors in the fossil-fired power plant,specifically from the protection configuration of high voltage asynehronous motor,the relationship Letween the protection of motor and protection of high voltage frequency changer,The protection function that high voltage variable frequency speed control system should own (sueh as undervoltage protection,restartable function after instantaneous shutdown,input overcurrent protection etc.)etc.aspects approaches the matters needing attention in the protection function configuration of high voltage variable frequeney speed control system of auxiliary machines in the fossil-fired power plants,providing references for the type selection and scheme determination of high voltage variable frequency speed control system of auxiliary machines in the fussil-fired power plants. |
| Keywords: | fossil-fired power plant auxiliary machines high voltage frequency changer protection configuration reliability |
