Abstract
A computer workstation-based interactive tool for assessing the reliability of power systems is disclosed. This tool can be used to determine the effect on the reliability of both substations and bulk generation and transmission systems of system additions, design alternatives, maintenance practices, substation configurations, and spare part policies. Each utility using the present invention is modeled analytically. The model includes load characteristics, demand projections, voltage profiles, energy and operating constraints, operator and automatic responses to the occurrence of contingent events, generating unit dispatch, contingency remedial actions, load shedding practices, demand-side management, and equipment failure modes including planned and unplanned maintenance.
