However, since such curves discretize into a few landmarks, important information is lost in the analysis, making it difficult to identify patterns of variation in start-up times and quantify differences in equity curves in terms of curve shape and separate individual and plant-level factors affecting start-up

Abstract

The invention provides an automated system and method for implementing statistical comparison of power plant operations. Systems and methods for analyzing power plant data include accessing data for one or more monitored parameters, generating a continuous time-series profile model (212) (e.g., by generalized additive model and / or principal curves techniques) of selected parameters during instances of at least one given type of power plant operation, and conducting shape analysis (214) by comparing the continuous time-series profile model of selected monitored parameters to an entitlement curve representing ideal performance for the at least one given type of power plant operation. Data associated with the profile modeling and shape analysis techniques may be provided as electronic output to a user (224). Additional steps or features may involve determining a capability index (216) for selected monitored parameters, clustering together (218) identified groups of profile models having similar profiles, monitoring (220) and / or optimizing parameters (222) to identify and improve power plant performance

Description

technical field [0001] The subject matter disclosed herein relates to systems and methods for enabling automated electronic analysis of power plant operations, and more particularly, to systems and methods for statistically comparing the shape and variation patterns of operating profiles of power plant operations. Background technique [0002] Highly complex industrial operations, such as those implemented within a power plant environment, often involve complex coordination of multiple machines and associated processes. Many industrial components within such a power plant environment may contain sensors or other monitoring equipment combined with computing devices so that the real-time condition of such components may be tracked electronically. For example, some display panels within a power plant environment are capable of displaying various current plant operating conditions associated with the respective components or processes being monitored within the plant. [0003] ...
