Topological Interlocking of Operational Switching

详细

Positions of interconnected switching devices determine the topological interlocks of switching operations at substations. The paper reviews two approaches for implementing programmable topological interlocks: offline and online. The paper highlights the disadvantages of offline and flexibility of online solutions. Anew object-topology approach to modeling of electrical networks is described. It allows applying the standard rules of topological interlocking automatically, both offline and online. An example of such automation is provided.
