Systems and methods for the configuration of substation remote terminals with a central controller are provided. A message identifying a current status of a remote terminal unit (“RTU”) associated with a remote power substation may be received by a central controller associated with a power system.
Systems and methods for the configuration of substation remote terminals with a central controller are provided. A message identifying a current status of a remote terminal unit (“RTU”) associated with a remote power substation may be received by a central controller associated with a power system. Based upon an analysis of the received message, a request for configuration data associated with the RTU may be communicated by the central controller to the RTU. In response to the request, the configuration data may be received by the central controller from the RTU. Based upon the received configuration data, the central controller may update a configuration database comprising information associated with the configuration of the RTU. In this regard, supervisory control and data acquisitions operations with the RTU by the central controller may be facilitated.

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; andif 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. 2. The method of claim 1, wherein receiving the configuration data comprises receiving the configuration data in one of (i) a Common Information Model (CIM) format or (ii) a specified format in Extensible Markup Language (XML). 3. The method of claim 1, further comprising: identifying, by the central controller, a desired format for receiving the configuration data,wherein communicating a request for configuration data comprises communicating a request for configuration data formatted in accordance with the identified desired format. 4. The method of claim 1, wherein communicating a request for configuration data comprises: determining, based upon an analysis of the received message, that the RTU has not previously been configured with the central controller; andcommunicating the request based upon the determination that the RTU has not previously been configured with the central controller. 5. The method of claim 1, wherein receiving a message identifying a current status of the RTU comprises receiving a message including an identifier of a configuration version number associated with the RTU, and wherein determining that a configuration of the RTU has been altered comprises: comparing the configuration version number to a stored configuration version number associated with the RTU; anddetermining that the configuration version number does not match the stored configuration version number. 6. The method of claim 1, wherein the at least a portion of the received configuration data was not deleted from the configuration queue. 7. A system for configuration of a substation remote terminal with a central controller, the system comprising: a central controller associated with a power system; anda remote terminal unit (RTU) situated at a power substation associated with the power system, the remote terminal unit configured to (i) communicate, to the central controller, a message identifying a current status of the RTU, (ii) receive, from the central controller, a request for configuration data associated with the RTU, and (iii) communicate the requested configuration data to the central controller,wherein the central controller is configured to (i) receive the message communicated by the RTU, (ii) communicate the request for configuration data based upon an analysis of the received message, 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, (iii) receive the configuration data, and (iv) store 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; (v) determine whether the configuration associated with the RTU is valid based at least in part on the configuration data; (vi) if the configuration associated with the RTU is not valid, then delete 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 update, 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. 8. The system of claim 7, wherein the configuration data is formatted in accordance with one of (i) a Common Information Model (CIM) format or (ii) a specified format in Extensible Markup Language (XML). 9. The system of claim 7, wherein the central controller is further configured to identify a desired format for receiving the configuration data, and wherein the request comprises an identification of the desired format. 10. The system of claim 7, wherein: the central controller is further configured to determine, based upon an analysis of the received message, that the RTU has not previously been configured with the central controller, andthe request is communicated based at least in part on the determination that the RTU has not previously been configured with the central controller. 11. The system of claim 7, wherein: the received message comprises an identifier of a configuration version number associated with the RTU, andwherein the central controller determines that the configuration of the RTU has been altered by (i) comparing the configuration version number to a stored configuration version number associated with the RTU and (ii) determining that the configuration version number does not match the stored configuration version number. 12. The system of claim 7, wherein the at least a portion of the received configuration data was not deleted from the configuration queue. 13.
