POWER FACTOR CORRECTION USING STATIC CAPACITOR: A CASE STUDY OF NIGERIAN 330KV GRID SYSTEM
This paper work is concerned with the power factor correction using static capacitor being a case study of Nigerian 330kV Grid System. The research involves collection of various data relevant to the study from National Control Centre (NCC), Osogbo. The analysis is limited to the generator buses that have low power factors. Presented in this paper work is also the mathematical modeling of equations involving system monthly and annual savings. Simulations were done using MATLAB software package. The value of the static capacitor adopted and injected in each of the generator buses is 30kVar which is within the acceptable range of 25kVar to 40kVar. Where low power factors were noticed at the generator bus, static capacitor is injected to correct the low power factors especially at those buses. Typical examples are buses 2 (Jebba), 3 (Shiroro), 4 (Sapele), 5 (Delta) and 6 (Afam). The injection of static capacitor further leads to reduction in the load current in each of the generator buses and consequently, an increase in the system annual savings.
