Wide Area - Protection and Monitoring

As interconnected power system size grew over the years, the magnitude of system-wide disturbances in power systems grew as well. Protection and control actions are needed to arrest the propagation of large power disturbances, stop the power system degradation and restore the system to a normal state. Control centers have the obligation to act, with limited information, on a very complex situation and often use heuristics and pre-defined procedures to be able to normalize the situation quickly. Local protection systems, which only rely on locally available measurements, are not capable to protect the entire power system. More
