| dc.description.abstract | The application of probabilistic techniques in the area of composite generation and transmission system reliability evaluation is now receiving considerable attention. This thesis attempts to further the state of the art in composite system reliability evaluation by including the effect of varying weather conditions. The thesis illustrates the development and analysis of several models which can be used to represent a fluctuating environment. Models presented. in this thesis are used to examine the sensitivity of selected reliability indices to individual parameter variation in a composite test system. A previously developed composite computer program based on simulation and load flow analysis of "credible" outage conditions has been extended by including the weather effects. During stormy weather periods, the failure rate of a component can increase sharply and the probability of overlapping failures can be much greater than that existing in normal weather periods. This phenomenon is called "failure bunching" due to the fact that components are fully or partially exposed to a common weather condition. Component failures, therefore, are not randomly distributed throughout the year but are more probable in constrained short periods in the year. Evaluation techniques for composite system reliability assessment are presented in this thesis which include varying weather conditions. Several methods, designated as the approximate equation technique, the full Markov state process, the approximate four-state approach and the line or area addition method are presented and discussed. The impact of these weather models on composite generation and transmission system adequacy indices are compared and discussed in the thesis. | |
