Space and Time Challenges in High Voltage Substation Projects

Abstract— Construction of High Voltage substations in the heart of cities is becoming more and more difficult. The small size of available land, the difficulties associated with the entrance and exit of high voltage overhead lines, the increasing protest of neighbors, high priority of projects and short schedule to energize these substations are some of the common problems for those who work in the design and execution department at any electric utility company. The dimensions of specified land for the project of 63/20 KV substation was very small and irregular. The incoming lines should have gone underground. Planned time to provide the GIS (Gas Insulated Substations) equipment is too long and could not satisfy the projects schedule. Under such conditions, if some colleagues suggest new ways to solve problems regardless of the fact that they already have proven solutions and also new solutions bringing along new problems as well, what would the client's reply be to their solutions? Perhaps it depends on whether the new method is able to solve the old and new problems at the same time or not?
