| Popis: | Structural health monitoring (SHM) systems are recently developed for many structures from a variety of industrial branches: aviation, civil engineering, marine, power engineering, etc. One of the sensor types that can be applied for SHM systems are fibre Bragg grating (FBG) sensors. The paper presents an FBG sensors based SHM system for monitoring the technical condition of a 3 kW organic Rankine cycle (ORC) microturbine. Microturbines of this type are used to generate electricity in cogeneration systems that can be fed with various fossil and renewable sources or even waste heat. FBG sensors were chosen due to their advantages, like small size and low weight, high temperature and corrosion resistance, ability to operate in an aggressive environment as well as the absence of electric current in measurement array. The aim of the research is the determination of FBG sensors applicability for SHM of ORC microturbine’s components. The sensors were used for determination of temperature distribution as well as detection of a leakage of a low-boiling medium. The temperature values determined from FBG sensors measurements were compared with those measured by infrared thermography (IRT) method. |
