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

摘要

The invention relates to control and fault analysis method in a thermal power plant by use of plant data specification during normal operation of the plant. The method comprises a) obtaining at least one set point information from the provided plant data specification containing list of process parameters and process outputs (S001, S002); b) controlling one or more control loops by providing set points for control based on the obtained one or more set point information from the plant data specification to operate the thermal power plant (S005); c) identifying gaps in controlling the said one or more control loops in the thermal power plant specification and iteratively manipulating at least one set point to meet the demand (S006); d) updating the plant data specification based on the manipulated at least one set point used to meet the demand (S007); and e) using the updated plant data specification for control of the plant to meet the demand (S004). A control system based on the method is also provided.
