Abstract

Methods and systems for modifying a turbine control system may be provided for. A method may include replacing at least one legacy main controller processor communicating in a first communication protocol with a current main control processor communicating in a second communication protocol, retaining at least one legacy IO processor in communication with at least one turbine monitoring device communicating in the first communication protocol, and providing at least one converter in communication with the current main controller processor or processors and in communication with the legacy IO processor or processors. The converter may translate communications between the current main controller processor or processors and the legacy IO processor or processors by translating between the second communication protocol and the first communication protocol.

Claims

1. A method for modifying a turbine control system, comprising:

replacing at least one legacy main controller processor communicating in a first communication protocol with at least one current main control processor communicating in a second communication protocol;

retaining at least one legacy IO processor in communication with at least one turbine monitoring device communicating in said first communication protocol; and

providing at least one converter in communication with said at least one current main controller processor and in communication with said at least one legacy IO processor;

wherein said at least one converter translates communications from said at least one current main controller processor from said second communication protocol to said first communication protocol and further transmits the communications to said at least one legacy IO processor; and

wherein said at least one converter translates communications from said at least one legacy IO processor from said first communication protocol to said second communication protocol and further transmits the communications to said at least one current main controller processor.

2. The method of claim 1, wherein said first communication protocol comprises at least one of the following:

RS485 protocol or ARCNET protocol; and

wherein said second communication protocol comprises Ethernet protocol.

3. The method of claim 1, further comprising retaining at least one legacy terminal board in communication with said at least one legacy IO processor.

4. The method of claim 1, wherein said at least one legacy main controller processor communicating in said first communication protocol is associated with a legacy turbine control system;

and wherein said current main control processor communicating in said second communication protocol is associated with current turbine control system.

5. The method of claim 1, further comprising:

replacing at least one legacy communications processor communicating in a third communication protocol with a current communications processor communicating in a second communication protocol;

retaining at least one legacy peripheral auxiliary turbine component communicating in said third communication protocol; and

providing a second converter in communication with said at least one legacy peripheral auxiliary turbine component and in communication with said at least one current communications processor;

wherein said second converter translates communications from said at least one current communications processor from said second communication protocol to said third communication protocol and further transmits the communications to said at least one peripheral auxiliary turbine component; and

wherein said second converter translates communications from said at least one legacy peripheral auxiliary turbine component from said third communication protocol to said second communication protocol and further transmits the communications to said at least one current communications processor.

6. The method of claim 5, wherein said at least one legacy peripheral auxiliary turbine component comprises a second control system.

7. The method of claim 5, wherein said third communication protocol comprises ARCNET protocol.

8. A control system for controlling at least one turbine, comprising:

at least one IO processor in communication with at least one turbine monitoring device, and configured to communicate in a first communication protocol;

at least one converter in communication with said at least one IO processor; and

at least one main controller processor in communication with said at least one converter, and configured to communicate in a second communication protocol;

wherein said at least one converter is configured to translate communications from said at least one IO processor to said at least one main controller processor by translating said first communication protocol to said second communication protocol, and to translate communications from said at least one main controller processor to said at least one IO processor by translating said second communication protocol to said first communication protocol.

9. The system of claim 8, wherein said first communication protocol comprises at least one of the following:

RS485 protocol or ARCNET protocol; and

wherein said second communication protocol comprises Ethernet protocol.

10. The system of claim 8, further comprising at least one legacy terminal board in communication with said at least one IO processor.

11. The system of claim 8, comprising a plurality of main controller processors configured in redundant, parallel communication.

12. The system of claim 8, comprising one main controller processor configured in non-redundant, simplex communication.

13. The system of claim 8, wherein said at least one main controller processor is associated with a current turbine control system, and is upgraded from a legacy turbine control system.

14. The system of claim 8, further comprising:

at least one legacy peripheral auxiliary turbine component communicating in a third communication protocol;

at least one current communications processor; and

a second converter in communication with said at least one legacy peripheral auxiliary turbine component and in communication with said at least one current communications processor;
