Practical Ways to Improve SAIDI and SAIFI Power Supply Reliability Indicators in an MV Grid
Main Article Content
Abstract
Based on a mathematical model of an existing MV network and analysis of its failures, remedies to improve SAIDI and SAIFI reliability indicators are proposed. Factors are identified and described that significantly affect electricity supply interruptions’ duration, frequency of their occurrence, and the number of not supplied recipients. A methodology is proposed for a relatively quick location of the failure site, isolation of the damaged grid element, and restoration of the supply of as many recipients as possible, considering the specificity of grids in mountainous areas. By simulation of potential failures based on the deterministic reliability model (DRM), the effectiveness of the adopted solutions is demonstrated in the perspective of a dozen years or so.
