Abstract

A system and method for enhancing operation of a power generation system. The method includes receiving forecasts at a predictive control unit. The method also includes accessing via a controller real-time lifing models or near real-time lifing models in the predictive control unit. Additionally, the method includes accessing via the controller an enhancer configured to simulate operation of a power generating unit in the power generation system to generate an enhancement of the power generation system based on the forecasts and the real-time or near real-time lifing models.

Claims

1. A power plant management device comprising:

a predictive control unit comprising;

a memory configured to store at least one lifing model correlated to a part life of a power generating unit and an enhancer configured to simulate operation of the power generating unit; and

a controller configured to access the enhancer and the at least one lifing model to generate at least one setpoint indicative of operating conditions for the power generating unit based on utilization of the at least one lifing model during operation of the enhancer, wherein the controller is configured to schedule a maintenance outage of the power generating unit based on the at least one setpoint.

2. The power plant management device of claim 1, wherein the predictive control unit is configured to update the at least one lifing model in the memory with real-time or near real-time received data.

3. The power plant management device of claim 1, wherein the at least one setpoint comprises a firing temperature for the power generating unit.

4. The power plant management device of claim 1, comprising a regulatory unit configured to receive the at least one setpoint from the controller and adjust operating conditions for the power generating unit based on the at least one setpoint.

5. The power plant management device of claim 1, wherein the predictive control unit is configured to receive forecasts relating to predicted conditions affecting operation of the power generating unit and wherein the controller is configured to access the received forecasts for utilization by the enhancer during operation of the enhancer.

6. A power generation system, comprising:

a power generating unit;

a predictive control unit comprising;

a memory storing an enhancer configured to simulate operation of the power generating unit based on at least one lifing model correlated to a part life of the power generating unit and at least one forecast relating to predicted conditions affecting operation of the power generating unit; and

a controller configured to generate at least one setpoint indicative of operating conditions for the power generating unit via the enhancer, wherein the controller is configured to transmit the at least one setpoint to schedule a maintenance outage of the power generating unit; and

a regulatory unit coupled to the power generating unit, wherein the regulatory unit is configured to receive the at least one setpoint from the controller and adjust operating conditions for the power generating unit based on the at least one setpoint.

7. The power generation system of claim 6, wherein the at least one forecast comprises data indicative of fuel price, ambient temperature information, or electricity price.

8. The power generation system of claim 6, wherein controller is configured to adjust weight factors of a first forecast relative to a second forecast during simulation of operation of the power generating unit.

9. The power generation system of claim 6, wherein the controller is configured to generate the at least one setpoint to change a first rate of part life wear of at least a first part in the power generating unit relative to a second rate of part life wear of at least a second part in the power generating unit.

10. The power generation system of claim 6, wherein the controller is configured to generate the at least one setpoint to enhance profitability of the power generating unit.

11. The power generation system of claim 6, wherein the least one setpoint comprises a firing temperature or a fuel split for the power generating unit.

12. The power generation system of claim 6, wherein the controller is configured to account for a throw-away cost of parts to in the power generating unit to enhance profitability of the power generating unit.

13. A method for enhancing operation of a power generation system, comprising:

receiving forecasts at a predictive control unit;

accessing real-time lifing models correlated to part lives of elements in a power generating unit or near real-time lifing models correlated to part lives of elements in a power generating unit via a controller in the predictive control unit; and

accessing via the controller an enhancer configured to simulate operation of the power generating unit in the power generation system to generate an enhancement of the power generation system based on the forecasts and the real-time or near real-time lifing models, wherein generating the enhancement of the power generation system comprises accessing current conditions affecting the power generation system and applying the current conditions affecting the power generation system with the real-time or near real-time lifing models and the forecasts to execute simulations of operation of the power generation system; and
