Effects on Voltage Stability of Line Contingency in Different Points

35913

There are many conditions for determining the voltage-maximum loading relationship in multi-bus power systems. One of these is the line contingency in power systems. In this study, Effects on voltage stability of the line contingency occurred different points in IEEE 14 buses power system. Line contingency is considered as disabled for a certain period of time of the breakers situated in line. The effects of line contingency at 19 points on the voltage-loading parameter were observed. Besides, In this study, the effects of bus voltage profile changes were investigated. As a result of this study, it has been seen that line contingency decrease the system loading parameter value and operating limits in different transmission lines. In particular, the line contingency between the state transmission line 2-3, which brought the loading parameter value and the operating limits to the critical value.
