Abstract
The invention relates to a method for detecting a leak in an energy converter system () containing a gas. A pressure regulator () is used to regulate a gas pressure in the energy converter system (), and the pressure regulator () has a gas metering valve (). The method has the following steps: a. measuring an inlet pressure () of the pressure regulator () and measuring an outlet pressure () of the pressure regulator (), b. measuring an output variable () of the energy converter system () and calculating a gas requirement in the energy converter system () on the basis of the output variable () of the energy converter system (), c. determining a first calculated flow () through the pressure regulator () on the basis of the measured inlet pressure () of the pressure regulator () and the measured outlet pressure () of the pressure regulator (), d. determining a second calculated flow () through the pressure regulator () on the basis of the gas requirement, e. comparing the first calculated flow () with the second calculated flow () by generating a first comparison value () from the first calculated flow () and the second calculated flow (), and f. determining a first threshold () and generating an error signal () if the value of the comparison value () is greater than the first threshold ().
