Abstract

A method and device for processing abnormal values ​​of thermal power generation data, characterized in that the method comprises the following steps: Step 1, selecting a main measuring point and a plurality of slave measuring points from all measuring points of the thermal power generating set, and Collect the operating data of the master and slave measuring points; step 2, carry out correlation analysis on the operating data of the master measuring point and the operating data of the slave measuring points, and establish the linear relationship with the highest correlation; step 3, based on the highest correlation The linear relationship of the main measuring point generates the operating data threshold of the subordinate measuring points, and eliminates invalid operating data according to the threshold. The method of the invention has simple and convenient steps, high efficiency and accurate results, and does not cause the pressure of data processing in the system.

Description

technical field

[0001] The invention relates to the field of power generation, and more specifically, to a method and device for processing abnormal values ​​of power generation data of a thermal power unit. Background technique

[0002] With the rapid development and progress of the power industry, the demand for power in all walks of life is gradually increasing. Therefore, technologies such as the actual operating status, performance testing, and fault diagnosis and early warning of each link in the thermal power unit have received more and more attention. .

[0003] At present, in order to enable each equipment and link in the thermal power unit to be monitored and detected accurately in real time, a large number of data monitoring and collection points are usually set up in the thermal power unit system to monitor abnormal data. However, since thermal power units usually operate in relatively harsh environments, all the data collected by data monitoring and collection ...

Examples

Embodiment Construction

[0029] The application will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present application.

[0030] figure 1 It is a schematic flowchart of steps of a method for processing abnormal values ​​of power generation data of a thermal power unit according to the present invention. like figure 1 As shown, the first aspect of the present invention relates to a method for processing abnormal values ​​of power generation data of a thermal power unit, wherein the method includes the following steps: Step 1, selecting a main measuring point and a plurality of slave measuring points from all measuring points of a thermal power unit, And collect the running data of master and slave measuring points.

[0031] It can be understood that, in the present invention, multiple measuring points can be set in ...
