This thesis presents a method for evaluating thereliability indices of distribution systems. The calculation isperformed by using failure mode and effect analysis. Thesereliability indices are used to improve and build distributionsystems in right way. A computer program is developed on a microcomputer by usinga software package : dBASE III Plus. The program consists oftwo parts namely system performance and system prediction. Firstpart is used to analyse MEA system. Load point indices andoverall system indices are calculated to compare with existingindices of MEA. It is found that these new indices have more indetail, precision and clearing of system understanding. The second part is used to find load point indices andoverall system indices of new distribution systems for studyingvariable effects. It is found that system configuration,operating policy, active and stuck breaker cases will have someeffects to reliability indices in differrent ways. |
