Problems solved by technology

This type of architecture is vulnerable to the inability of the central data collection system to store and archive the data generated by the devices in the wind farm if the wind farm network infrastructure fails
For example, loss of connectivity between a Supervisory Control (command) and Data Acquisition (SCADA) master and a wind turbine can lead to loss of operational data and erroneous logging of wind turbines

Embodiment Construction

[0010] The techniques described herein allow wind turbine generator wind farm systems to collect data for use, for example, in generator control. In one embodiment, a combined master-slave supervisory control and data acquisition (SCADA) architecture provides real-time monitoring and control as well as user visualization, historical data archiving and reporting, configuration management, Functions to assist data processing, fault logging, alarming and / or remote user access. In one embodiment, the architecture provides near real-time monitoring and control of wind farm equipment locally and remotely, while also facilitating archiving of individual wind turbine operational data as well as aggregated wind farm data.

[0011] In one embodiment, the architecture uses client devices within the wind turbines, wind farm meteorological masts, and / or wind farm substations to provide a communication interface (real-time and file transfer). The architecture also provides real-time data ...

Abstract

Wind turbine generator wind farm systems to collect data for use for wind farm control. A combination master-slave supervisory command and data acquisition (SCADA) architecture together with distributed databases local to the data producing device within a wind farm provide functionality for real-time monitoring and control as well as secondary data processing and / or remote user access. The architecture facilitates approximately real-time monitoring and control of devices in the wind farm both locally and remotely while also facilitating reliable archiving of operational data of individual wind turbines as well as totalized wind farm data.

Description

technical field [0001] The invention relates to the control of a plurality of wind turbine generators. More specifically, the present invention relates to control and data acquisition of wind farms with multiple wind turbine generators. Background technique [0002] Historically, wind turbines have contributed very little to the overall power generation used to power the grid. Low equipment ratings (<100 kW) and uncertain availability of wind sources make the impact of wind turbine generators negligible when grid operators consider grid security. However, currently available are wind turbine generators with a rating of 1.5 MW or more. Furthermore, many power generation developers are installing wind farms with one hundred or more wind turbine generators. The power "chunks" available from a wind farm with a 1.5 MW wind turbine generator are comparable to modern gas turbine generators. Therefore, wind turbine generators are increasingly becoming a viable power source fo...
