Nigerian electric power supply quality improvement

Abstract

Improving the quality of the Nigeria electric power supply means improving voltage, transient and frequency stabilities. Power system voltages are controlled by the reactive power component of the power supply; hence voltage and transient stabilities can be improved by using reactive power compensators to either supply or absorb reactive power from the system when necessary. Power flow algorithm can be developed and used to monitor the various bus voltages. Power equations can also be used to forecast the extra quantity of reactive power that will be needed to aid voltage stability at any given time. Also, power equations will be used to test if the available compensation devices can protect the power system from probable transient voltages. Frequency stability can be improved by using real power balance method. Power equations will be used to check for balance in real power generated to the system and real power demanded from the system (plus estimated real power losses). If there is no balance, real power load will then be added or withdrawn from the system if the imbalance favour the real power generated or the real power demanded respectively.
