Abstract
The repeatedcase of power system collapse in the Nigerian National Grid isof a great concern and need to be investigated. This research paper discusses the effect of voltage collapse and the methods of power generation with respect to the Nigerian National Grid. Other major causes of voltage instability were also examined.Politics has been known to be one of the major factors responsible for epileptic power supply in the country as a result of corruption within the power sector. Single Line Diagram (SLD) showing all the generating stations and transmission network and the distances covered is also presented. Results recorded an average of twenty five disturbances over a period of twenty three years under investigation (January, 1995- July, 2017). 2003is the year with the highest number of faults recorded over the period of twenty three years, representing 8.95% of the total faults. Similarly, the year 1999 recorded the least number of faultsrepresenting 1.52% over the same period.The partial grid collapse and total grid collapse disturbances represent49% and 51% respectively. Only four power stations out of the fourteen are identified to be operating on full installed capacity. The thermal plants represents 76% while 24% for hydro power plants across the country. Collated results are tabulated, exhaustively discussed and analysed using tables, charts and graphs. Appropriate recommendations are also presented such that if implemented will proffer lasting solutions to the challenges confronting the power sector in Nigeria.
