Some aspects of generating unit availability models

A comparison is presented of some of the basic generating unit performance data from the North American Electric Reliability Council-Generating Availability Data System (NERC-GADS) and the Canadian Electrical Association-Equipment Reliability Information System (CEA-ERIS) reporting procedures. The authors also illustrate some of the additional information which can be produced from the continuous state monitoring procedure used by the CEA. This is exemplified by Weibull analysis of state residence time distributions, consideration of the effect of low operating factors for conventional fossil fuel units, and modified models for peaking units.<
