<p><P>PROBLEM TO BE SOLVED: To provide an operation method for an engine generator capable of suppressing inrush current generated in supplying electric power from the engine generator for manually opening and closing a breaker to a motor and a pump. <P>SOLUTION: When a breaker is opened, an excitation circuit or a power circuit of an automatic voltage regulator is shut down to stop a power generation state of a generator. When an engine is switched to an idling state and the breaker is turned on, the engine is kept in a rated rotating state, the excitation circuit or the power circuit of the automatic voltage regulator is turned on, and the electric power lacking in first generator excitation power from the automatic voltage regulator at the first generator excitation is supplied from an auxiliary power supply. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
