Abstract

The embodiment of the invention discloses a power generation load steady state point extraction method and a device thereof, so as to solve the technical problem that extraction of a steady state load point from frequent-fluctuation historical data usually consumes large manpower and material resources and requires a unit to stop operating. The method of the embodiment of the invention comprises steps: S1, historical power generation load data are extracted from real-time operation data, and a power generation load data column vector D=[d1, d2,...,dN]<T> after equal-length sampling is recorded, wherein the N is the load data sample number; S2, the average value and the variance of the D and the bandwidth of a kernel density function determined by the variance are calculated; S3, the maximum value and the minimum value of the load data are found out, the load range is equally divided into preset parts, and the kernel density function is calculated; S4, the increment of the kernel density function is calculated; and S5, the symbol of the kernel density function increment is checked, and the load steady state point is determined.

Description

technical field

[0001] The invention relates to the field of data analysis of thermal power generation production, in particular to a method and device for extracting a steady-state point of power generation load. Background technique

[0002] In the power generation data analysis of power plants, it is often necessary to analyze the operating conditions of the generator set under a certain steady-state load condition. However, due to the needs of power production scheduling, the power generation load always changes frequently with the grid dispatching command (AGC command), that is, the load data includes both fast-tracking dynamic data and steady-state data when the AGC command is stable. In the data analysis of generating units, the extraction of steady-state load points is an important task, and different steady-state loads represent different operating conditions.

[0003] At present, the usual practice in power plants is to implement thermal experiments, and fix the l...
