Assignee: CRRC ZHUZHOU LOCOMOTIVE CO., LTD.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 3:
4. The energy balance control method according to claim 1, wherein in step 5, an output voltage of the power pack, when a rated power of the power pack is output at the rotating speed, is determined according to the rotating speed of the power pack, then the voltage of the intermediate DC circuit is calculated from the voltage when the rated power is output at the rotating speed, and the specific calculation formula is:

Uintermediate=1.28×Urated, wherein Uintermediate is the voltage of the intermediate DC circuit corresponding to the rotating speed of the power pack, and Urated is the output voltage of the power pack when the rated power of the power pack is output at the rotating speed of the power pack.
