Introduced through policy instruments, as well as due to increase awareness of and demand for energy, alternative, renewable energy sources are becoming increasingly popular and necessary. The growing market and standards are forcing producers of renewable energy sources to constantly improve the quality of their products. Biomass trigenerators are one way of obtaining such energy, both in the form of electricity, heat and cold. These are elements generating steam by burning various solid, liquid or gaseous fuels of organic origin. Rotating machines in the form of turbines or steam engines are used to generate electricity. Unfortunately, they are particularly exposed to steam impacts associated with discontinuous work. This article presents the monitoring and prevention system for such impacts. It is based on the analysis of the frequency spectrum of vibrations of such generators and can be used to implement a trigenerator control system that will reduce the influence of such impacts. With proposed diagnostic system, the efficiency and life span of a Renewable Energy Source can increase significantly.
