POWER GENERATION CONTROL METHOD OF HYBRID CONSTRUCTION MACHINE AND HYBRID CONSTRUCTION MACHINE

摘要

A power generation control method of a hybrid construction machine in which the voltage of a capacitor can be maintained in an appropriate range while minimizing the capacitance of the capacitor and the system can be prevented surely from becoming inoperative. A hybrid construction machine is also provided. Slewing power corresponding to power consumption of a motor for slewing one portion of the main body for other portion is calculated in succession, value of the slewing power thus calculated is converted into a smaller value, power generation commands of a generator-motor are created in succession by using the converted values and the power generation command is delivered to an inverter for driving the generator-motor.
