Remote wind turbine reset system and method

摘要

The present invention includes a Computer Assisted Reset (CAR) system that allows a central operations team to remotely reset turbine faults across multiple wind turbine platforms and SCADA systems with a single interface. The system also allows automatic resets to occur. One aspect of the invention includes a Modbus to OPC Translator. The translator permits the implementation of a system where a PLC located at wind turbine control sites can accept control messages or commands organized or formatted in accordance with the Modbus protocol and sent over an Internet Protocol connection, with the translator receiving the requests through the PLC and generating an appropriate OPC (“OLE Process Control”) request. The OPC request may then be passed onto a corresponding OPC server residing in the SCADA system for each wind turbine control site.

主权项

1. A system for resetting turbines comprising:
a plurality of turbines; a remote alarm monitor system for issuing Modbus requests to control all or a subset of the plurality of turbines at once; and a plurality of PLCs corresponding to the plurality of turbines, each PLC configured to receive Modbus requests and process the requests in accordance with a type of turbine associated with that PLC; wherein said plurality of PLCs monitor the status of said plurality of turbines and provides status information to said remote alarm monitor system; wherein said plurality of PLCs poll a wind site SCADA system associated with the plurality of turbines to determine status information; and wherein said wind site SCADA system associated with the plurality of turbines comprises an OPC server and a module for receiving Modbus turbine control requests processed by PLCs and translating these requests into OPC control requests.
