Description
technical field [0001] The invention relates to the field of a control system of a large gas generating set, in particular to a one-button start control system and method for a large gas generating set. Background technique [0002] Due to the low speed of large gas generator sets, the control of the mixing ratio of gas and air (hereinafter referred to as the air-fuel ratio) is complicated, the generator excitation and synchronization detection are difficult to be connected to the grid, and the stability control of the gas generator set after grid connection is difficult. One-key startup has always been a technical problem that plagues developers. The large gas generator set is composed of gas intake, engine control unit, air-fuel ratio control unit, generator control unit, one-button start core control unit and other control parts. Due to the influence of sensor technology, the air-fuel ratio control unit cannot adjust the appropriate air-fuel ratio at the initial stage of...
