Claims (4)
1. En fremgangsmåde til overvågning af en vindmølles (1) vingefrekvenser bestående af et tårn (2), en nacelle (3), et nav (4) og mindst tre roterende vinger (5), hvor et accelerometer eller en G-sensor (6) placeret i nacellen (3) registrerer vibrationerne i nacellen (3), og hvor en sensor registrerer vingernes (5) roterende vinkel azimut (Φ), kendetegnet ved følgende trin: - Modulering af de registrerede signaler eller vibrationer fra G-sensoren (6) ved anvendelse af den registrerede azimut vinkel (Φ) i kombination med G-sensor signalerne; - Uddragning af vingefrekvenserne ved anvendelse af en Fast Fourier Transformation (FFT eller DFFT) eller en Phase Locked Loop oscillation (PLL) på de modulerede G-sensor (6) signaler; - Beregning af en ny frekvens for hver vinge (5) ved at sammenligne hver enkelt vingefrekvens med de andre vingefrekvenser og bruge denne sammenligning til at beregne ændringen i hver vingefrekvens.
2. En fremgangsmåde ifølge krav 1, kendetegnet ved yderligere at omfatte sætning af en alarm, når den nye beregnede frekvens når op på et vist niveau.
3. Et overvågningssystem som overvåger en vindmølles (1) vingefrekvenser indeholdende et tårn (2), en nacelle (3), et nav (4) og en eller flere roterende vinger (5}, hvor et accelerometer eller en G-sensor (6 ) placeret i nacellen (3) registrerer vibrationerne i nacellen (3) i en tværgående og en langsgående retning, og hvor en sensor registrerer vingernes (5} roterende azimut vinkel (Φ), en styreenhed eller beregningsenhed med input fra de registrerede signaler, kendetegnet ved at styreenheden eller beregningsenheden indeholder en moduleringsenhed, der modulerer de registrerede signaler, en Fast Fourier Transformation (FFT eller DFFT) enhed eller en Phase Locked Loop oscillations (PLL) enhed, som uddrager hver vingefrekvens fra det modulerede signal.
4. Et overvågningssystem ifølge krav 3, kendetegnet ved yderligere at indeholde en alarm enhed i styreenheden, som sætter en alarm og/eller standser vindmøllen (1), når ændringen af hver vingefrekvens når op på et vist niveau.
