Abstract

Systems and apparatuses include a first controller structured to control a first power system object located on a first route of a power system, and a second controller structured to control a second power system object located on a second route of the power system. The first controller and the second controller are both structured to perform a route level function including coordination of actions of the first power system object and the second power system object, and the first controller is a principal controller and the second controller is a participant controller.

Claims (50)

1. A system, comprising:

a first controller structured to control a first power system object located on a first route of a power system; and

a second controller structured to control a second power system object located on a second route of the power system,

wherein the first controller and the second controller are both structured to generate an active route list and determine route states associated with the first route or the second route based on a switch action processing function,

wherein the first controller and the second controller are both structured to perform a route level function including coordination of actions of the first power system object and the second power system object, and

wherein the first controller is a principal controller and the second controller is a participant controller.

2. The system of claim 1 , wherein the participant controller is inhibited from performing the route level function.

3. The system of claim 1 , wherein the participant controller computes outputs of the route level function asynchronously from the principal controller and the outputs of the participant controller are not used to coordinate actions of the first power system object and the second power system object.

4. The system of claim 1 , wherein the participant controller computes outputs of the route level function in synchronicity with the principal controller and the outputs of the participant controller are not used to coordinate actions of the first power system object and the second power system object.

5. The system of claim 1 , wherein the route level function performed by the principal controller receives inputs from the principal controller and the participant controller.

6. The system of claim 1 , wherein the second controller performs the route level function in the event the first controller is unable to perform the route level function.

7. The system of claim 1 , wherein the first controller defines a first object ID and the second controller defines a second object ID that defines a higher value than the first object ID, and

wherein the principal controller is selected based on a lowest available object ID.

8. The system of claim 1 , further comprising a third controller structured to control the first power system object,

wherein the third controller is a redundant controller structured to perform the route level function including coordination of actions of the first power system object and the second power system object.

9. The system of claim 1 , wherein the first power system object is arranged on both the first route and the second route.

10. A system, comprising:

a first controller structured to control a first power system object located on a first route of a power system, and to receive route level inputs and perform a route level function including coordination of actions of the first power system object; and

a second controller structured to control a second power system object located on a second route of the power system, and to receive the route level inputs and perform the route level function including coordination of actions of the second power system object,

wherein the first route is based on a one-line topology and includes a source object and a first bus object,

wherein the second route is based on the one-line topology and includes the source object and a second bus object,

wherein the route level inputs including information regarding the first route and the second route, and the route level function affects operation of the first route and the second route.

11. The system of claim 10 , wherein the first controller is structured to receive only route level inputs related to coordination of actions of the first power system object.

12. The system of claim 10 , wherein the first controller and the second controller compute the route level function synchronously or asynchronously.

13. The system of claim 10 , further comprising a third controller structured to control the first power system object,

wherein the third controller is a redundant controller structured to perform the route level function.

14. The system of claim 10 , wherein the first controller is a first genset controller and the second controller is a second genset controller, and

wherein the route level function includes a load sharing function.

15. The system of claim 14 , wherein the first genset controller is structured to:

publish a first load value data,

receive a second load value data from the second genset controller,

compute an average load based on the first load value data and the second load value data, and

control power output of the first power system object to achieve the average load.

16. A system, comprising:

a first controller structured to

control a first power system object of a power system,

determine a plurality of point-to-point routes based on a one-line topology,

assign a route identifier to each of the plurality of routes, and

determine a route priority for each of the plurality of routes and associated with each route identifier;

a second controller structured to control a second power system object of the power system,

wherein the first controller and the second controller are both structured to perform a first route level function that includes coordination of actions of the first power system object and the second power system object, and

wherein the first controller is a principal controller and the second controller is a participant controller;

a third controller structured to control a third power system object of the power system, and to receive route level inputs and perform a second route level function including coordination of actions of the third power system object; and

a fourth controller structured to control a fourth power system object of the power system, and to receive the route level inputs and perform the second route level function including coordination of actions of the fourth power system object,

wherein the first route level function and the second route level function are based on the route priority.

17. The system of claim 16 , wherein the participant controller is inhibited from performing the first route level function.

18. The system of claim 16 , wherein the participant controller computes outputs of the first route level function asynchronously from the principal controller and the outputs of the participant controller are not used to coordinate actions of the first power system object and the second power system object.

19. The system of claim 16 , wherein the participant controller computes outputs of the first route level function in synchronicity with the principal controller and the outputs of the participant controller are not used to coordinate actions of the first power system object and the second power system object.

20. The system of claim 16 , further comprising a redundant controller structured to perform at least one of the first route level function or the second route level function.

21. The system of claim 16 , wherein any of the first controller, the second controller, the third controller, or the fourth controller can be structured on a shared circuit.
