METHOD FOR OPTIMIZATION OF CONTROL AND FAULT ANALYSIS IN A THERMAL POWER PLANT

摘要

An exemplary control system performs a control and fault analysis method in a thermal power plant using plant data specifications during normal operation of the plant. The method includes obtaining information for at least one set point from the plant data specification which includes a list of process parameters and process outputs. One or more control loops are controlled by providing set points for control based on the information obtained for the at least one set point to operate the thermal power plant and identifying gaps in controlling the one or more control loops in the thermal power plant specification and at least one set point is iteratively manipulated to meet the demand. Further, the plant data specification is updated based on the manipulated at least one set point used to meet the demand, and the updated plant data specification is used for controlling the plant to meet the demand.

1. A method for controlling of a thermal power plant to provide electrical power per demand, the thermal power plant having process units and one or more actuators for regulating process parameters associated with the process units, the method comprising:
obtaining information for at least one set point from a plant data specification that includes a list of process parameters and process outputs, wherein the plant data specification is provided by a manufacturer of the process units; controlling one or more control loops in the thermal power plant by providing set points for control based on the obtained information for the at least one set point to operate the thermal power plant; identifying gaps in controlling the one or more control loops in the thermal power plant specification and iteratively manipulating at least one set point to meet the demand; updating the plant data specification based on the manipulated at least one set point used to meet the demand; providing conditionally, feed forward signals to the one or more actuators as an additional bias, wherein the additional bias is estimated based on the updated plant data specification and a difference between the demand and actual generation values; and using the updated plant data specification and the feed forward signals for control of the thermal power of the plant to meet the demand.
