Incorporating Substation Related Outages in Composite System Reliability Evaluation

Abstract :

The reliability evaluation of a bulk power system normally includes the independent outages of generating units, transformers and transmission lines. Station originated outages, can, however, also have a significant effect on the composite system adequacy indices. Terminal station related failure events such as failures of eakers, transformers and bus sections are a major cause of multiple outages of major components (generators and/or transmission lines etc.). This paper illustrates the effects of terminal stations in composite system reliability evaluation by using the RBTS Reliability Test System (RBTS). The paper also presents a basic reliability test system. The basic system data necessary for adequacy evaluation at the generation and composite generation and transmission system levels are presented together with the fundamental data required to conduct reliability cost/reliability worth evaluation.
