Improving Contingency Evaluation In Nigerian 330kv Transmission Grid Using Intelligent Based SSVC

Abstract

The consistent power failure in Nigerian 330 KV transmission network that had crippled business activities was overcame by introducing improving contingency evaluation in Nigerian 330kv transmission grid using intelligent based SSVC. contingency challenges in Nigerian 330kV transmission grid was characterized and established, conventional SIMULINK model Nigerian 330kV transmission grid was designed, SSVC rule base that will minimize the causes of contingency challenges in Nigerian 330kV transmission grid was developed and ANN was trained in the developed SSVC rule base for immediate minimization of the causes of contingency challenges in Nigerian 330kV transmission grid. Then an algorithm that would implement the process was developed and SIMULINK model for improving contingency evaluation in Nigerian 330KV transmission grid using intelligent based SSVC was designed and results obtained were validated and justified.  The results obtained were the conventional Transformer Failure Rate that causes contingency challenges in Nigerian 330kV transmission grid was22%. On the other hand, when an intelligent based SSVC was imbibed into the system, it concurrently reduced it to19.8 %. Finally, with these results obtained, it definitely showed that the percentage improvement in contingency evaluation in Nigerian 330KV transmission grid when an intelligent based SSVC was integrated in the system was2.2%. To characterize and establish the causes of contingency challenges in Nigerian 330kV transmission grid. To design conventional SIMULINK model Nigerian 330kV transmission grid. To develop an SSVC rule base that will minimize the causes of contingency challenges in Nigerian 330kV transmission grid. To train ANN in the developed SSVC rule base for immediate minimization of the causes of contingency challenges in Nigerian 330kV transmission grid. To develop an algorithm that will implement the process. To design a SIMULINK model for Improving contingency evaluation in Nigerian 330KV transmission grid using intelligent based SSVC. To validate and justify percentage improvement in the reduction of causes of contingency challenges in Nigerian 330kV transmission grid with and without an intelligent based SSVC
