Abstract:
1. A method for automatically controlling a stationary gas engine, comprising the steps of: computing a speed control deviation (dn) from a set speed (nSL) and an actual speed (nIST); using the speed control deviation (dn) in a speed controller to determine a set torque (MSL) as a correcting variable; using the set torque (MSL) to determine a set volume flow (VSL); determining a mixture throttle angle (DKW 1 , DKW 2 ), for determining a mixture volume flow (V 1 , V 2 ) and for determining an actual mixture pressure (p 1 (IST), p 2 (IST)) in a receiver tube ( 12 , 13 ) upstream of intake valves of the gas engine, as a function of the set volume flow (VSL); and determining a gas throttle angle, for determining a gas volume flow (VG) as a gas fraction in a gas/air mixture, as a function of the set volume flow (VSL).
