Abstract:
1. A method for configuring a substation remote terminal with a central controller, the method comprising: receiving, by a central controller associated with a power system from a remote terminal unit (RTU) associated with a remote power substation, a message identifying a current status of the RTU; communicating, by the central controller to the RTU based upon an analysis of the received message, a request for configuration data associated with the RTU, wherein the analysis comprises determining that a configuration associated with the RTU has been altered based at least in part on a comparison between a configuration identifier in the received message and a stored configuration identifier; receiving, by the central controller from the RTU in response to the request, the configuration data; storing, by the central controller, the configuration data in a configuration queue for validation, wherein at least a first portion of the configuration data is associated with one or more substation devices in communication with the RTU; determining, by the central controller, whether the configuration associated with the RTU is valid based at least in part on the configuration data; if the configuration associated with the RTU is not valid, then deleting from the configuration queue, by the central controller, at least a second portion of the configuration data associated with at least one of the one or more substation devices; and if the configuration associated with the RTU is valid, then updating, by the central controller based upon at least a portion of the received configuration data, a configuration database comprising information associated with the configuration of the RTU in order to facilitate supervisory control and data acquisition operations with the RTU by the central controller.
