Abstract

The invention discloses a novel graphical description method for power loads, and belongs to the technical field of power quality analysis methods. The method comprises a new graphical description method for the power load, and a conversion method for converting load data into RGB data is designed. The sensitivity of naked eyes of people to the hue in the HSV color model is utilized, and a load image conforming to observation of people is designed on the basis of hue change. According to the load image, the load data of the object at all moments can be displayed in one image, so that the ruleof using the load by the user can be better presented. The new load data image description method is helpful for carrying out load data missing completion, user classification identification, load prediction and the like, is also helpful for applying various latest deep learning methods to an electric power system, is an important supplement to the existing load data visualization, and has very important practical significance.

Description

technical field

[0001] The invention relates to a new method for graphical description of power load, and belongs to the technical field of power system load analysis method and data visualization. Background technique

[0002] Electric load, also known as "electric load". The sum of the electric power that the electric energy user's electric equipment draws from the power system at a certain moment is called the electric load. According to the different load characteristics of power users, the power load can be divided into various industrial loads, agricultural loads, transportation loads and people's domestic power loads.

[0003] Load curves are often used to view load changes over time and to study the regularity of load changes. According to the type of load, it can be divided into active power curve and reactive power curve; according to the length of time period, it can be divided into daily load curve (in units of 1 hour / 15 minutes), monthly load curve (in units o...
