Model based control with engine perturbation feedback

摘要

A method to control an power generation plant including: applying control settings to operate the plant; collecting plant data indicative of the performance of the plant; applying the control settings to a model of the plant; collecting prediction data from the model; comparing the plant data to the predicted data and adjusting the control settings applied to the plant and model; perturbing the control settings and applying the perturbed control settings to operate the plant and the model; collecting perturbed plant data and perturbed prediction data, and modifying the model if the perturbed plant data represents an improvement as compared to the perturbed prediction data.

1. A method to control a power generation plant comprising:
applying control settings to operate the power generation plant; collecting plant data indicative of the performance of the power generation plant operating at the control settings in real time, wherein the control settings represent values for control parameters applied at certain periods of time during the real time operation; applying the control settings to a model of the power generation plant, wherein the model simulates the real time operation of the power plant and the control settings are applied to the model simultaneously with the application of the control settings to the power generation plant and the control settings applied to the model represent the same values for the control parameters at the same certain periods as applied to the power generation plant; collecting prediction data from the model indicative of the predicted performance of the power generation plant operating with the applied control settings; comparing the engine data to the predicted data to adjust the control settings applied to the power generation plant and model; perturbing at least one of the control settings and applying the at least one perturbed control settings to operate the power generation plant and to the model; collecting perturbed engine data indicative of the performance of the power generation plant operating at the at least one perturbed control settings; collecting perturbed prediction data from the model indicating the predicted performance of the engine operating at the applied perturbed control settings, and modifying the model if the perturbed power generation plant data represents an improvement as compared to the perturbed prediction data.
