Improving Voltage Stability in Nigerian 330kv Transmission Network Using Intelligent Solid State Var Compensator (SSVC)
The low performance of power supply in the transmission network is as a result of voltage instability, this is overcome by improving voltage stability in Nigerian 330kv transmission network using intelligent solid state var compensator (SSVC). It is achieved in this procedure by running the load flow from the characterized data thereby locating the faulty buses that their per unit volts do not fall within the ranges of 0.95 through 1.05, designing a conventional model for voltage stability in Nigerian 330KV transmission network, designing SIMULINK model for SSVC, designing a rule base that will enhance the faulty buses to attain voltage stability. Integrating the designed SIMULINK model for SSVC to designed rule base and designing a SIMULINK model for improving voltage stability in Nigerian 330KV transmission network using intelligent solid state var compensator. The results obtained were as follows: In bus1 the conventional per unit volts is 0.92P.U.volts which did not reach the range of voltage stability of 0.95 through 1.05 P.U.volts. On the other hand, when intelligent solid state var compensator (ssvc) is incorporated in the system the per unit volts becomes 0.9779P.U.volts thereby attaining voltage stability that enhances power supply. In bus 9 the conventional per unit volts is 0.922P.U.volts which did not attain the voltage stability range of 0.95 through 1.05 P.U.volts. On the other hand, when intelligent solid state var compensator (ssvc) is incorporated in the system the per unit volts becomes 0.9801P.U.volts thereby attaining voltage stability that enhances power supply.
