Stationary gas engine protecting device for stationary power generating facility of vehicle, has determining unit determining power value, and changing unit changing set power value such that supplied power is equal to pre-determined value
Résumé
The device (24) has a measuring unit i.e. sensor (26), measuring a quantity i.e. methane index (IM), representing combustion behavior of gas supplied to a stationary gas engine (12). A determining unit (28) determines an optimum electrical power value (Peopt) to be achieved based on the measured quantity representing the combustion behavior of the measured combustion gas. A changing unit (30) changes a set power value (Pc) such that supplied electrical power (Pe) is equal to the pre-determined optimum electrical power value. Independent claims are also included for the following: (1) a method of protecting a stationary gas engine (2) a method of generating a digital drift cartography.
