Operating Reliability Analysis of Peaking Generating Units Considering Start-Up Failures and Degradation
The peaking generating units such as gas and hydro turbines have been widely for providing operating reserve during real time operation of power systems. These generating units usually require a short lead time to start, synchronize and carry load. If the unit starts up successfully, it will transit to the in-service state for generation. However, if the unit fails to start-up or meets a random failure during operation, it goes into the failure state, which may have serious impact on system reliability. In this paper, a multi-state model has been developed for peaking generating units considering their start-up failures and degradation. The conceptual modeling and corresponding reliability solutions for peaking generating units have been comprehensively analyzed.
