RESUMO

After a number of collapses due to the extreme use of the transmission lines, the voltage stability, or voltage security, became an important issue. This work was developed in order to contribute to a voltage security reinforcement method. The method calculates control actions to decrease the power flowing through the critical branch of the most loaded transmission path associated with the critical bus (concepts present in this dissertation). For this propose, and considering that the power flow in a transmission network may be restricted by voltage stability limits, transmission congestion analysis methods were study. Two of them deal with the contribution of real and reactive outflows of individual generator buses, and real and reactive inflows of individual load buses, in all network branches. Another method assess the impact of a given power transaction on the network. Numerical examples are presented to illustrate whether it is the possible or not to employ the studied methods in the voltage security reinforcement problem.
