Abstract:
The occurrence of loadshedding under normal operating condition in Distribution Network caused a lot of inconveniences to the consumer. However, there is need to examine the state of the distribution network to know the performance without load shedding under normal condition. This research examines the state of Auchi distribution network without load shedding. In order to achieve the aim of the research data was obtained from the distribution company, the modelling of the distribution network obtained was done using ETAP and the load flow simulation was done using Newton Raphson Algorithm to determine the power flow in the network, Bus voltage, losses along the line and transformer losses. The results of the study show that at 80% loading of the transformers in the network, the voltage supply to the consumer is bad under normal condition, since the two out of three 33 kV bus voltages is below the acceptable range of plus or minus 5% of the nominal voltage. Likewise, almost all 11 kV and 0.415kV voltages in the network is below the acceptable limit of plus or minus 10% of the nominal voltage. Furthermore, the result indicates that active power loss in the network is 0.2MW which is very high. This research therefore recommends that the voltage profile of AUCHI distribution network needs improvement in order to improve the quality of supply. Also, since the supply from the grid is be allocated based on the generating capacity this research also recommends that DISCO in charge of Auchi distribution network should also considering the usage of DG in the network which can perform a dual purpose of voltage improvement and addition of power supplied.
