Thermal Power Stations' Reliability Evaluation in a Hydrothermal System
Abstract
A quantitative tool for the evaluation of thermal power stations reliability in a hydrothermal system is presented. A reliable power station is one which would supply the required power within its installed capacity at any time within the specified voltage and frequency limits. Required for this evaluation are the station's installed capacity and available generation. A reliability index for making this evaluation is highlighted. The effectiveness of this approach is demonstrated using a sample power system, National Electric Power Authority’s (NEPA) system and the reliability evaluated. The results obtained are presented and discussed.
