METHOD AND DEVICE FOR CONTROLLING STARTING OF POWER GENERATION SYSTEM

This is a method for controlling starting of a power generation system including an internal combustion engine as a power source, an electrical generator, and a power transmission mechanism that transmits power between the internal combustion engine and the electrical generator, the method executes a rotation speed control of driving the electrical generator by using electric power supplied from a battery, and matching a rotation speed of the electrical generator with a target rotation speed at the time of starting the power generation system. According to the method, output possible electric power of the battery is acquired, and the rotation speed of the electrical generator is acquired. A filtering process of reducing a component of a resonance frequency band of a spring-mass system including the internal combustion engine, the electrical generator, and the power transmission mechanism is executed on the rotation speed of the electrical generator. Further, an upper limit torque that is an upper limit value of a torque of the electrical generator is calculated based on the filtered rotation speed of the electrical generator and the output possible electric power of the battery. In addition, the rotation speed control is executed under a limitation of the upper limit torque.
