Abstract

Various methods and apparatus are described in which a power management controller having process control software controls output power characteristics for a group of wind turbine generators. The power management controller also has a network interface configured to allow a user of a supervisory and control network to remotely access and change output power settings of the group of wind turbine generators through a secure connection established over a network connection.

Claims

1. A method, comprising:

establishing a first secure connection between a supervisory and control network and a first location via a networked environment;

establishing a second secure connection between the supervisory and control network and a network interface associated with a group of wind turbine generators using a local area network; and

changing a setting from the first location to cause a change in output power characteristics of one or more wind turbine generators in the group of wind turbine generators using the network interface, wherein the first location is remote to the group of wind turbine generators.

2. The method of claim 1, further comprising:

providing terminal services that present the network interface to multiple locations including the first location, which allows the user to change a setting effecting operations of the group of wind turbine generators.

3. The method of claim 1 wherein the network interface is used to control VARs of the group of wind turbine generators.

4. The method of claim 1, further comprising:

viewing and changing parameters of the group of wind turbine generators based on user indicia using one or more of a plurality of levels of access to access the network interface.

5. The method of claim 1, further comprising:

changing parameters of a wind park containing the group of wind turbine generators other than the output power characteristics of the group of wind turbine generators from the first location via the network interface.

6. The method of claim 1 further comprising:

using a secure connection software to establish the first secure connection.

7. An apparatus, comprising:

a power management controller having process control software to control output power characteristics for a group of wind turbine generators; and

a network interface, responsive to the power management controller, to allow a user of a supervisory and control network to remotely access and change output power settings of the group of wind turbine generators through a secure network connection.

8. The apparatus of claim 7, further comprising:

a server located with the group of wind turbines to provide terminal emulation services to one or more terminals with access to the supervisory and control network.

9. The apparatus of claim 8, wherein the network interface is provided by a terminal emulation service.

10. The apparatus of claim 7, further comprising:

a server to provide security for a local domain by referencing a database of access information, wherein the server cross-references a user accessing the network interface with the access information in the database to determine whether to allow the user access to the supervisory and control network.

11. The apparatus of claim 7, wherein the network connection is through a cable connecting the supervisory and control network to the power management controller, wherein the cable has a bandwidth to support digital transmission at least at a rate of one gigabytes per second.

12. The apparatus of claim 7, further comprising:

a web server located with the group of wind turbines to communicate an IP address for the network interface and provide Web services.

13. The apparatus of claim 7, wherein the supervisory and control network has resident secure connection software to allow secure remote access to the supervisory and control network for an individual.

14. The apparatus of claim 7, wherein the power management controller has resident secure connection software to allow secure individual remote access to a web page associated with the power management controller.

15. The apparatus of claim 7 wherein the power management controller is a programmable logic controller for a dynamic Volt-Ampere Reactive system.

16. The apparatus of claim 7, wherein the network interface is remotely accessible over a Plain Old Telephone System (POTS) line.

17. An apparatus, comprising:

means for establishing a first secure connection between a supervisory and control network and a first location via a networked environment;

means for establishing a second secure connection between the supervisory and control network and a network interface associated with a group of wind turbine generators using a local area network; and

changing a setting from the first location to cause a change in output power characteristics of one or more wind turbine generators in the group of wind turbine generators using the network interface, wherein the first location is remote to the group of wind turbine generators.

18. The apparatus of claim 17, further comprising:

means for providing terminal services that present the network interface to multiple locations including the first location, which allows the user to change a setting effecting operations of the group of wind turbine generators.

19. The apparatus of claim 17, further comprising:

viewing and changing parameters of the group of wind turbine generators based on user indicia using one or more of a plurality of levels of access, such as user identification and password, accessing the network interface.

20. The apparatus of claim 17, further comprising:

means for changing parameters of a wind park containing the group of wind turbine generators other than the output power characteristics of the group of wind turbine generators from the first location via the network interface.
