Abstract

The method (200) for obtaining operating parameters of a power plant includes data mining (202) a database of historical operating conditions for the power plant with a partitioning clustering algorithm to generate a statistical model, and taking current operating condition data of the power plant into account Dynamic operating condition target values ​​are internally calculated ( 204 ) based on the statistical model. The method also includes performing (208) a real-time energy loss calculation based on the dynamic operating condition target value and automatically identifying (210) at least one operating parameter of the power plant based on the energy loss calculation. The partitioning clustering algorithm may be a k-means clustering algorithm.

Description

Technical field [0001] The disclosed embodiments relate to energy production, and more particularly to the operation of power plants. Background technique [0002] Condition Monitoring System (CMS) is an automated system used to monitor the parameters of machines (such as power plants) in order to predict failures, perform maintenance, and adjust performance. Fossil fuel power plants, for example, can use CMS to help operators optimize the performance of the power plant. One of the ways CMS accomplishes this task is to determine the cause of energy loss by performing an energy loss analysis. [0003] The "operating conditions" of a power plant refers to the premise on which the power plant operates. Air temperature is an example of operating conditions in a power plant. The operating conditions of the power plant with the least equivalent fossil fuel consumption are called "optimum conditions" or "optimum operating conditions". The optimal conditions of the power plant can be c...
