Abstract

One embodiment of the present invention provides a system for performing a real-time, in-the-field switching-sequence simulation for a power system that includes a plurality of switching devices. During operation, the system receives, at a hand-held device, topology information associated with the power system, a set of user-definable rules, and a request to perform an operation on a switching device in the power system. In response to the request, the system identifies the switching device from the plurality of switching devices, obtains instant status information associated with the plurality of switching devices, and runs a simulation based on the topology information, the user-definable rules, the status information, and the identified switch device. The system determines whether the operation is allowed based on an outcome of the simulation.
