Authors: *Agbontaen F.O, Ike S.A
The loadabilty analysis of the existing 330 kV Nigeria transmission network is presented in this paper. Newton-Raphson algorithm in Etap 12.6 was used to simulate and analyze the network. The parameters used for the study include bus data, transmission line power rating, generators active power, transformer rating and base load. The total installed capacity of the base case considered is 11,948MW out of which 4,420.4MW was available for load level of 3,633.6MW. Result obtained showed that the maximum load the existing 330kV network can accommodate and evacuate is 4,948.978MW and 1,448.721MVar when the buses were subjected to different percentage of the base case load and generation.
