| Abstract: | The configuration principle of the adjustable speed system with a series capacitive compensator is described. The parameter reckoning formulas of series capacitive compensator are introduced. In this paper, the system open-loop and closed-loop characteristic curves, power factor curves, efficiency curves and test waves are also give. Experimental results indicate that this system can greatly improve IM operating performance as well as rise IM power factor and efficiency. The power factor rises to 0.94 and the efficiency rises to 0.92 in total power output range. Under identical conditions, as compared with non-capacitive compensator system, the total efficiency of this system rises about 3%. |
