Reactive Switching Simulation in Security Analysis At Florida Power and Light System Control Center

This paper describes a method for simulating the switching of reactive devices in the Security Analysis function at Florida Power and Light Company System Control Center. The method closely simulates the automatic switching of reactive devices in the field, resolves problems of non-convergence of some highly critical contingencies, provides tools for a better VAR management and reactive device control, and thus relieves the system operator from the guesswork in interpreting Security Analysis results. Real time results are also presented to show the effectiveness of the method.
