A SOFTWARE APPROACH AND ANALYSIS IN VOLTAGE STABILITY AND IMPROVEMENT OF A POWER NETWORK

ABSTRACT-Power demand increases steadily while the expansion of power generation, transmission has been severely limited due to inadequate resource and environmental forces. As demand is increasing day by day, the generation cannot be increased with matching of demands because fossil fuel is restricted and cost factors are there. The load area are far away from generation side so only one possibility to give the power to load area by minimizing the losses of transmission lines by proper analyzing of transient stability. The voltage stability is not match standard values for all period of times when the line is heavily loaded severe transient oscillations will occurs. In peak hour period, at that period if fault is also occurred due to unbalance current flow through the transmission network as a result a severe voltage oscillation occurred in transmission lines. As we are not get enough tariff from distribution section, then loss will become more costly. So it is very much necessary to analyses transient stability, voltage stability and power flow through power network systems. There are several methods for analyzing voltage and transient stability like FACTS devices etc. But all these methods create extra cost for transmission and Generation Company which will be bear by them only. So here we analyses simulation method i.e. capacitor improvement method for voltage stability
