| সংক্ষিপ্ত: | The use of Corrective Switching technique to eliminate overloads in electrical systems,
addressed in several studies in the last decades, has proved to be a very effective load flow
control technique. Some of these studies are based on electrical circuit theories or Relief
Function methodologies. Network switching causes changes to the system configuration and
consequently the short-circuit levels of the buses are changed. These changes can lead to a
network insecure operation when the protection parameters are not modified, since the
overcurrent protection functions are based on the values of the rated currents and the shortcircuit currents, which are previously defined in the protection studies. Adaptive Protection
techniques makes it possible to recalculate the network protection parameters in real time, for
any system configuration, enabling network operation with optimized protection settings. The
purpose of this work is to implement the Corrective Switching technique, using, as a restriction
condition in the choice of switching variants, the adjustments of the network protection
parameters. If the network operation is not safe for the configuration proposed by the relief
variants, new network protection parameters are calculated, as well as coordination and
selectivity, is adopted and the Adaptative Protection technique is implemented. The network is
automatically reconfigured through the Self Healing technique. |
