Abstract
A method to control the operational status of a wind turbine is provided. An operator communication interface establishes a wireless point-to-point communication to a wind turbine communication interface. The wind turbine communication interface is an integrated part of the wind turbine. A control signal is transmitted from the operator communication interface via the point-to-point communication to the turbine communication interface. The control signal is transferred from the turbine communication interface to an internal control system of the wind turbine. The internal control system of the wind turbine changes the operational status of the wind turbine based on the control signal.
Claims15
A method, comprising:
- providing a wind turbine having an integrated wind turbine communication interface, wherein the wind turbine is controlled by a first control signal via a first communication, and wherein the first communication is via Internet/SCADA,
- receiving a second communication from an operator communication interface, wherein the second communication is a remote wireless point-to-point direct communication to the wind turbine communication interface, wherein the remote wireless point-to-point direct communication is a short range communication implemented according to the principles of Bluetooth or DECT or WiFi, or an extended range communication, implemented according to the principles of GSM or GPRS or EDGE or WCDMA or HSPA or LTE, or an optical communication,
- wherein the remote wireless point-to-point direct communication is not a connection via Internet/SCADA, and wherein the second communication comprises a second control signal transmitted from the operator communication interface to the wind turbine communication interface,
- transferring the second control signal from the wind turbine communication interface to an internal control system of the wind turbine, and
- changing the operational status of the wind turbine based on the second control signal, wherein the second control signal received via the second communication overrides the first control signal received via the first communication.

A method to control an operational status of a wind turbine, comprising:
- providing a wind turbine communication interface, wherein the wind turbine communication interface is an integrated part of the wind turbine and includes two wireless transponders, wherein the two wireless transponders are connected to respective coupled switches of a safety relay module, wherein the safety relay module is connected to a redundant emergency stop circuit of the wind turbine, wherein the wind turbine is controlled by a first control signal via a first communication, and wherein the first communication is via Internet/SCADA;
- establishing a second communication, wherein the second communication is a remote wireless point-to-point direct communication between the wind turbine communication interface and an operator communication interface;
- receiving a second control signal from the operator communication interface via the second communication;
- and
- activating the redundant emergency stop circuit of the wind turbine based on the second control signal, wherein activating the redundant emergency stop circuit of the wind turbine based on the second control signal overrides the first control signal.

A wind turbine comprising:
- a wind turbine communication interface having two wireless transponders, wherein the two wireless transponders are connected to respective coupled switches of a safety relay module, wherein the safety relay module is connected to a redundant emergency stop circuit;
- wherein the wind turbine is controlled by a first control signal via a first communication, and wherein the first communication is via Internet/SCADA;
- wherein the two wireless transponders are configured to establish a second communication, wherein the second communication is a remote wireless point-to-point direct communication with a remote operator communication interface, receive a second control signal from the remote operator communication interface via the second communication, and activate the redundant emergency stop circuit based on the second control signal;
- wherein, the redundant emergency stop circuit activated based on the second control signal has a higher priority than the first control signal received via the first communication and the redundant emergency stop circuit activated based on the second control signal overrules the first control signal received via the first communication.
