Effect of Station Originated Outages in a Composite System Adequacy Evaluation of the IEEE Reliability Test System

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 breakers, transformers and bus sections are a major cause of multiple outages of major cxxponents (generators and/or transmission lines etc.). This paper illustrates the effects of terminal stations in composite system reliability evaluation by using the IEEE Reliability Test System (RTS). The paper also provides a valuable extension of the original RWS by including switching configurations at each bus.

Composite Generation and Transmission System Adequacy Evaluation Including Protection System Failure Modes

Protection systems are normally considered to be perfectly reliable in composite system adequacy assessment. The effect on the calculated adequacy indices of neglecting these events can be quite significant in highly redundant configurations. This paper examines some protection system models and incorporates the results in a practical application of cmxposite systemtadequacy assessment.
