Method and apparatus for preventing misoperation in an electric power system

摘要

One embodiment provides a computer system for preventing switching errors in a power system that includes a plurality of switching devices. The system includes a topology-extraction mechanism configured to extract topology information associated with the power system; a status database configured to store status information associated with the switching devices; a rule database configured to store user-definable operation rules associated with the switching devices; a receiving mechanism configured to receive a request for performing a switching operation on a device; a simulation mechanism configured to perform a simulation based on the extracted topology information, the status information, and a rule associated with the device; a determination mechanism configured to determine whether the switching operation is allowed based on an outcome of the simulation; and a display mechanism configured to display an output of the determination mechanism.

1. A method for preventing switching errors in a power system that includes a plurality of switching devices, comprising:
extracting, by a computer, topology information associated with the power system; obtaining current status information associated with the switching devices; receiving, from a user, a request for performing a switching operation on a device in the power system; in response to receiving the request, extracting a basic operation rule associated with the device and the switching operation from a rule database that stores user-definable operation rules, wherein the extracted basic operation rule is independent of a location of the device in the extracted topology, wherein the extracted basic operation rule specifies a type of the device, a type of the switching operation, and a logic expression specific to the type of the device and the type of the switching operation, and wherein the logic expression of the extracted basic operation rule is independent of the extracted topology; performing a simulation based on the extracted topology, the obtained current status, and the extracted basic operation rule that is independent of the location of the device; determining whether the extracted basic operation rule is violated based on the simulation outcome; and in response to determining that the extracted basic operation rule is violated, displaying an error message to the user to prevent the user from performing the switching operation.
