Use and Failure Cause Analysis of Gas-Turbine Units at Distributed Generation Facilities

\nDistributed generation (DG) facilities commonly use gas-turbine units (GTU) varying in design and power. High manufacturing quality, reliability, efficiency, and low environmental impact are among the factors driving their popularity. This paper analyzes GTU reliability metrics and overviews the factors that may affect reliability of the units in use. It discusses the GTU design considerations that shall be borne in mind while engineering DG facilities and emergency automation devices. The paper further analyzes the recorded use GTUs at existing DG facilities from the perspective of the main causes and consequences of their failure.\n
