Abstract
Including a detailed substation model in transmission/distribution reliability studies can greatly increase the size and complexity of the entire system model. One possible solution to this problem is to decouple the substation reliability analysis from the transmission line/distribution feeder reliability analysis. This is important as it allows a detailed model of the substation included in transmission/distribution reliability studies to get accurate results.
This thesis presents a methodology for modeling, analyzing, and selecting suitable configurations for substations based on different criteria, such as reliability requirements, load flow, cost of interruption, initial investments, operation and maintenance. These criteria are combined in Life Cycle Costs (LCC) with associated interest rates and substation life cycle period.
A new method is presented for simulation of active failures and provides a considerable time saving. The principle depends on the S and SS groups, established for the nodes existing in basic minimal cut sets. The developed technique can be used in the development of computer programs for substation reliability evaluation.
The methodology is implemented by utilizing specialized tools for calculating reliability based on analytical techniques and estimating cost efficiency. It is applied for comparison between the most commonly used substation configurations using conventional and alternative technologies. To implement methodology the required software tools were developed.
