Design and Implementation of a Comprehensive Approach for the Evaluation of Power Transmission Grid Maintenance

One of the ways to increase the reliable and stable performance of power grids and reduce customer shutdowns is the proper planning of power grid maintenance. Many studies have been carried out in the area of selecting the best and most effective maintenance technique for each electrical equipment.  However, in order to ensure the successful design and implementation of these maintenance methods, it is required that a model be provided for assessing the status of power grids in terms of maintenance objectives. This paper proposes an appropriate and comprehensive strategic map based on a balanced scorecard model (BSC) with the help of technical knowledge and experience of the experts. The proposed strategic map describes maintenance strategies and plans for power transmission companies from four perspectives: financial, customer, internal processes, learning and growth along with strategic issues. Using the proposed method managers can identify the maintenance deficiencies by indexing and targeting strategic issues and their ongoing monitoring. At last, the prioritization can be done to eliminate the difficulties. Results show that by continuously evaluating all aspects of the transmission networks maintenance, increase in system availability can be observed.
