The present subject matter is directed to a system and method for controlling an electrical component, e.g. a power bridge, of a wind turbine using contingency communications. In one embodiment, the method includes receiving, by the electrical component, a standard set of commands for a first time frame. A next step includes receiving, by the electrical component, one or more contingency sets of commands for time frames beyond the first time frame. The method also includes determining if the standard set of commands is received within a start window of the first time frame. A further step includes implementing, by the electrical component, the standard set of commands during the first time frame if the standard set of commands is received within the start window. The method also includes implementing, by the electrical component, one of the contingency sets of commands received during a previous time frame if the standard set of commands is not received within the start window.

1. A method for controlling an electrical component of a wind turbine, the method comprising: receiving, by the electrical component, a standard set of commands for a first time frame;receiving, by the electrical component, one or more contingency sets of commands for time frames beyond the first time frame;determining if the standard set of commands is received within a start window of the first time frame;implementing, by the electrical component, the standard set of commands during the first time frame if the standard set of commands is received within the start window; and,implementing, by the electrical component, one of the contingency sets of commands received during a previous time frame if the standard set of commands is not received within the start window. 2. The method of claim 1, further comprising detecting whether the electrical component is controlled based on the standard set of commands or one of the contingency sets of commands and sending the detection to the controller. 3. The method of claim 1, further comprising overwriting the contingency set of commands received during a previous time frame if the standard set of commands is received within the start window of the first time frame. 4. The method of claim 1, wherein, if the electrical component is controlled based on the contingency set of commands, the method further comprises determining, by the controller, an error between the contingency set of commands and the standard set of commands and adjusting subsequent commands based on the error. 5. The method of claim 1, wherein the contingency sets of commands is calculated utilizing one or more algorithms. 6. The method of claim 5, wherein the one or more algorithms comprise one of or a combination of the following: a hold-last value, a stop value, a time/angle-based extrapolation, a zero-order hold value, higher-order extrapolation, or a melding technique. 7. The method of claim 1, wherein the electrical component comprises any one of or a combination of the following: a power converter, a bridge logic interface, a bridge rectifier, a power semiconductor device, or an insulated-gate bipolar transistor (IGBT). 8. A method for controlling an electrical component of a wind turbine, the method comprising: receiving, via the controller, the feedback communications from the electrical component;determining if the feedback communications are received by the controller within a start window of a first time frame;calculating, via the controller, a set of commands for the first time frame, wherein if the feedback communications are received within the start window of the first time frame, the calculations are based on the received feedback communications, and wherein if the feedback communications are not received within the start window of the first time frame, the calculations are based on an estimated feedback value; and,controlling the electrical component based on the set of commands applied during the first time frame. 9. The method of claim 8, wherein the set of commands comprises a standard set of commands and a contingency set of commands. 10. The method of claim 9, further comprising controlling the electrical component based on one of the standard set of commands or the contingency set of commands. 11. The method of claim 10, further comprising detecting whether the electrical component is controlled based on the standard set of commands or the contingency set of commands. 12. The method of claim 11, further comprising determining an error between the contingency set of commands and the standard set of commands. 13. The method of claim 12, further comprising adjusting subsequent calculated commands based on the error. 14. The method of claim 8, further comprising overwriting the contingency set of commands when the feedback communications are received within the start window of the first time frame. 15. The method of claim 8, wherein the estimated feedback value is calculated utilizing one or more algorithms, wherein the one or more algorithms comprise one of or a combination of the following: a hold-last value, a stop value, a time/angle-based extrapolation, a zero-order hold value, higher-order extrapolation, or a melding technique. 16. The method of claim 8, wherein the standard set of commands is determined based on the received feedback communications. 17. The method of claim 8, wherein the electrical component comprises one of a power converter, a bridge logic interface, a bridge rectifier, a power semiconductor device, or an insulated-gate bipolar transistor (IGBT). 18. A system for controlling an electrical component of a wind turbine, the system comprising: a controller communicatively coupled to one or more processors, the controller configured to: receive feedback communications from the electrical component;determine if the feedback communications are received within a start window of a first time frame;calculate a set of commands for the first time frame, wherein if the feedback communications are received within the start window of the first time frame, the calculations are based on the feedback communications, and wherein if the feedback communications are not received within the start window of the first time frame, the calculations are based on an estimated feedback value; and,control the electrical component based on the set of commands during the first time frame. 19. The system of claim 18, wherein the controller and the electrical component are communicatively coupled via a serial link. 20. The method of claim 18, wherein the electrical component comprises one of a power converter, a bridge logic interface, a bridge rectifier, a power semiconductor device, or an insulated-gate bipolar transistor (IGBT).
