Embodiment

[0113] This embodiment takes the high-temperature superheater of unit 1# of a thermal power plant as an object. The primary fan is an important equipment in the steam-water system of the boiler. Its structure is complex, it is difficult to establish an accurate mathematical mechanism model, and it is prone to frequent faults. Manual troubleshooting is difficult. It conforms to the adaptation scene of the present invention. Through the detailed elaboration of this embodiment, the implementation process of the present invention is further described.

[0114] The implementation steps of the embodiment of the present invention to optimize the working conditions of a certain power plant high-temperature superheater equipment are as follows:

[0115] Step 1: Select a total of 33 related indicators of high-temperature superheater equipment except shutdown. Including high inlet (outlet) temperature (°C), high wall temperature (°C), real power (MW), outlet pressure (kPa), etc., so the...

Abstract

A method for classifying operating conditions of electric equipment, comprising constructing training data for a mean value clustering model; preprocessing the training data, deleting invalid data, and performing normalization processing; using the K-means++ algorithm to determine the initial clustering center; determining The upper and lower limits of clustering division categories; cyclically realize the clustering process of multiple categories; evaluate and analyze the clustering results to determine the optimal K value of clustering categories; select the optimal K value model as the optimal working condition division result and other steps to improve efficiency and accuracy.

Description

technical field [0001] The invention relates to the field of division of operating conditions of thermal power plants, in particular to a method for dividing operating conditions of electric power equipment. Background technique [0002] In my country's coal-fired thermal power plants, the boiler steam-water system is widely used, and the high-temperature superheater, as an important part of the steam-water system, plays an important role in the normal operation of the entire boiler. However, in actual thermal power plants, problems such as coking and overheating of the heating surface, unreasonable installation, long-term fixed-point blowing, and long-term unqualified steam quality of high-temperature superheaters often occur during operation, which seriously threaten the safety and security of power plants. Economic Operation. At present, the normal operation of the high-temperature superheater of the steam-water system in most thermal power plants in China depends on the...
