Method for researching maximum load average value of resident living electricity users

Abstract

The invention discloses a method for researching the maximum load average value of resident living electricity users. The method comprises the steps of selecting users in different areas, selecting measurement objects, determining the sampling time, drawing a user electricity broken line graph, determining an electricity load maximum value and calculating an average value. The beneficial effects of the invention are that: t the method for researching the maximum load average value of the resident living electricity users is reasonable in design; the selected residential areas are divided intothree categories of urban residential users, suburb residential users and rural residential users according to living positions; therefore, the selected cell sample is more representative; the research result is more accurate; the user residence division types are divided according to residence rooms or residence areas; sampling time is set at an interval of 10 minutes, and data such as the current, the voltage, the active power, power factor values and the like of each measuring point are automatically recorded by using a tester, so that the base number of the acquired data is large enough, and a research result is more accurate when maximum load average value research is performed.

Description

technical field [0001] The invention relates to a research on the maximum load of civil electric households, in particular to a research method for the average maximum load of residential electric households, which belongs to the technical field of electric power systems. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, new residential quarters continue to emerge in cities, and higher and higher requirements are placed on the reliability of power supply from distribution networks. The distribution capacity of the residential area has important practical significance for the planning of the distribution network and its safe and economical operation. Accurately calculating the power load of the residential area and choosing a reasonable distribution and transformation facility can meet the current and future electricity needs of the residents of the community. It can also reasonably reduce the projec...

Problems solved by technology

The distribution capacity of the residential area has important practical significance for the planning of the distribution network and its safe and economical operation. Accurately calculating the power load of the residential area and choosing a reasonable distribution and transformation facility can meet the current and future electricity needs of the residents of the community. It can also reasonably reduce the project cost and save investment. The analysis and research on the average maximum load of electricity users can reasonably guide the selection of distribution transformers, wires, cables and other equipment in residential quarters. At present, there is no appropriate research method, so this application proposes a research method for the average value of the maximum load of residential electricity users
