SPECTRAL ANALYSIS IN GTPP CONTROL: A PATH TO ENHANCED DYNAMIC STABILITY AND EFFICIENCY.

The implementation of spectral analysis of instantaneous load power in gas turbine power plant (GTPP) control systems opens up new opportunities for enhancing dynamic stability, reliability, and efficiency. Based on the considered approaches (FFT, wavelet transform [5]), it is demonstrated that rapid detection and analysis of the signal's frequency components contribute to effective suppression of transient oscillations and resonance phenomena. As a result, the response time to disturbances is reduced, turbine component wear is minimized, fuel combustion processes are optimized, and harmful emissions are decreased. Furthermore, spectral methods can be easily integrated with modern technologies (artificial intelligence, digital twins), enhancing the flexibility of GTPPs in grids with a high share of renewable energy sources. The described practical results and prospects indicate the feasibility of further extending this approach to improve the global energy infrastructure.
