最佳回答
1. Acquisition induction motor running parameters; 2. When asynchronous motor when entering the electricity from the state grid disconnect; 3. Asynchronous motor and no-load excitation capacitor form island generating system, acquisition induction motor running parameters; 4. When asynchronous motor when entering electromotion state with the grid connection. Control device includes links in induction motor and ac power back to the road, and the first switch components in the first switch components connect the drive unit, computer controller and data collection units, induction motor is connected a no-load excitation capacitors. This invention will eliminate pour power phenomena and reactive compensation comprehensive consideration, is totally eliminates asynchronous motor fell power phenomenon, and make full use of asynchronous motors power can speed measurement, while in induction motor electric state reactive power compensation, is one of the best forms of energy saving method. 1, in asynchronous motor run
