ENHANCEMENT OF POWER FLOW CONTROL IN NIGERIA 330KV TRANSMISSION NETWORK USING D-FACTS DEVICES
Abstract
Nigeria power transmission systems need to be continuously up-graded and expanded in order to cater for the need of ever growing power demand. This paper investigated the effect of D-FACTS devices in enhancing power flow control in Nigeria 330kV transmission network so as to relieve the network of congestion, limit loop flows and improve assets utilization more efficiently than centralized FACTS devices. Six selected 330kV transmission lines across six geo-political zones in Nigeria were simulated for line flow control and real power flow control without and with insertion of D-FACTS devices in Nigeria 41bus system under different scenarios. Newton Raphson load flow method was used for A.C. load flow analysis. The simulations were done in PowerWorld environment. At the end, it was found that installation of multiple D-FACTS devices on few Nigeria 330KV transmission lines for coupled control of line flow and real power flow on the network had improved the reliability, controllability and transfer capacity of the existing transmission lines economically. It also served as most cost-effective alternative to construction of new transmission lines. The end results showed satisfactorily achievement as the line flow and power flow on the network became efficiently controllable. The transmission grid also proved smart, more reliable, fault tolerance and self-recoverable.
