METHOD TO CONTROL GAS TURBINE ENGINE Russian patent published in 2010 - IPC F02C9/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to gas turbine production and can be used in electronic ACS of gas turbine engines (GTE) designed to drive electric generators (EG) of gas turbine electric power stations (GTEPS). Proposed method additionally comprises measuring circuit voltage frequency and EG actual active power. On connecting GTEPWS into unlimited power circuit, after cutting in vacuum switch, turbine preset rpm is formed from two components, i.e. static and dynamic components. Note here that static component is defined to make the product of circuit voltage frequency by the factor that relates EG voltage frequency to turbine rpm and is determined on calculated and experimental basis and specified in engine acceptance tests. While dynamic component is defined as the product of difference between preset and actual EG active powers by incremental speed regulation set in acceptance tests and made more accurate in operating engine incorporated with GTEPS GTE.

EFFECT: higher reliability, fast operation.
