Embodiment Construction

[0021] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 Shown is the schematic diagram of the industrial load classification control method of the daily load curve of the present invention, as can be seen from the figure, the first step of the method is to obtain the daily load characteristic data by means of the substation integrated automation system for industrial load power supply or a separate instrument for obtaining daily load characteristic data. The typical 96-point daily load characteristic data of the industrial load working day is divided by the 96-point daily load active curve data of the typical industrial load working day.

[0023] The specific implementation method is to take the maximum value of the active power of the daily load curve of the industrial load as the power reference value, divide the daily load curve data at 96 points by the power reference value...

Abstract

The invention discloses an industrial load classification control method based on a daily load curve. According to the minimum value of per unit values of daily load curve data and the distribution rule of per unit value data, a judgment is made, and if the daily load feature is intermittent and only one work period exists, loads of the class are work loads in a certain fixed period; if multiple work periods exist, the loads of the class are work loads in multiple intermittent periods; if the daily load feature is continuous and the load fluctuation is small, the loads of the class are continuous working stable loads; if the daily load feature is continuous and the load fluctuation is large, the loads of the class are continuous working loads with the obvious peak-and-valley difference fluctuation. According to the four classes of industrial loads, different load control methods are adopted.

Description

technical field [0001] The invention belongs to the fields of load characteristic analysis, load classification and load control, and in particular relates to an industrial load classification control method based on daily load curves. Background technique [0002] The current power load classification is mainly based on the nature of the power load industry, which is divided into several types of power loads such as residential life, commerce, industry, and agricultural production. However, industrial load is a large category of load. There is no clear classification method for industrial load at present. It can only be divided according to its industrial type. At present, there are too many types of industries, such as metallurgy, steel, petroleum, chemical industry, machinery, cement, and coal. , electrified railway, aluminum processing, etc., how many types of industrial loads are currently unclear to most people. In order to achieve the targets of energy saving and emi...
