Wind farm control system
First Claim
1. A Supervisory Command and Data Acquisition (SCADA) system for managing a wind farm having an array of wind turbines for electric power generation and one or more meteorological sites, each wind turbine being located at a turbine site and electrically connected for power transmission to a substation located at a substation site, the system comprising:
- a turbine processing unit (TPU) located at each wind turbine, the TPU being a processing element functioning as the SCADA element for that turbine, the TPU being configured to collect data from the turbine and turbine site, to provide an interface to control the turbine, and to communicate with other parts of the system from the turbine site, the TPU being further configured to store locally at the TPU data collected from the turbine and turbine site;
a substation processing unit (SPU) located at the substation operating as the interface for the system to the substation, the SPU being a processing element functioning as the SCADA element for that substation, the SPU being configured to collect data from the substation, to communicate with other parts of the system, and to store locally at the SPU data collected from the substation;
a meteorological processing unit (MPU) located at each meteorological site functioning as the SCADA element for the site, the MPU being configured to collect meteorological data from sensors on and at a meteorology tower, to communicate with other parts of the system, and to store locally at the MPU data collected from sensors on and at a meteorology tower;
a data communication network;
a server coupled to communicate over the network with the wind turbines, the substation, and the one or more meteorological sites, the server being configured to receive data from them through their respective the SCADA elements (TPU, MPU, or SPU) and to provide signals to control the wind turbines and substation through their respective SCADA elements, the server being further configured to store data received from the wind turbines, meteorological sites, and substation at regular intervals and to perform database management on the received data; and
a user interface through which authorized users can exercise command and control functions for the wind farm.
