Abstract

This research aimed to model efficacious lightning protection scheme (MELPS) in Nigerian 11-132 kV substations using analytical models for evaluating both raw and derived data. Specific Transmission substations in the coastal area zone of Nigeria prone to lightning strike were selected as a case study. In order to assess the adequacy of protectiveness of 11 kV -132 kV existing substations, direct dimension of installations using measuring tape were carried out and installations were scaled down and modelled dimensionally using AutoCAD software in order to measure spatial parameters.  In order to achieve a proposed desired protective cone of protection, each tower was increased. The results obtained show that there are significant improvements in protective efficacy of proposed protective scheme model (PPSM) for the existing 33/11 kV and 132/33 kV substations. Under the PPSM, all 23 and 33 elements of both 33/11 kV and 132/33 kV substations respectively are adequately protected against lightning strike by obtained coverage factor assessment values and volume of protection evaluation. The PPSM overcomes the ruinous effects of lightning discharge in accordance with lightning protection level standard (99% probability of lightning efficiency). The proposed lightning scheme model is costlier than the existing lightning schemes: 30% and 50% for 33/11kV and 132/33 kV substations respectively. However, juxtaposing the cost with obtainable cost of repair or restoration due to C-G LS, the latter outweighs the cost. It is recommended that the existing protective systems should be reviewed for upgrading that will incorporate a hybrid design comprising sky wire and spike schemes with adequate parameter values in order to mitigate reported failures being caused by lightning in the systems.
