Determination method and device of zone load data acquisition point

Abstract

The invention provides a determination method and device of a zone load data acquisition point. A first node with maximum electric quantity data in a data structure chart of a target power distribution zone is determined by a first set generated according to a node data table and is used as a zone load data acquisition point for installing load data acquisition equipment, the problem of too many sets of load data acquisition equipment installed caused by the zone load data acquisition point arranged for a user is solved, the first set is updated if the recorded numbers of the zone load data acquisition points do not reach preset acquisition points, so that the other zone load data acquisition point is determined again until the recorded numbers of the zone load data acquisition points reach the preset acquisition points, the setting numbers of the zone load data acquisition points are reduced on the basis of completely acquiring electric quantity data of the user, and the time of acquiring electric quantity data of all users in a power distribution zone is reduced to improve zone load data acquisition efficiency.

Description

technical field [0001] The present invention relates to the technical field of power distribution, and more specifically relates to a method and device for determining load data collection points in a station area. Background technique [0002] Due to the randomness of user access and load changes in the low-voltage distribution station area, the three-phase load is unbalanced. The current flowing through the three-phase lines may vary greatly, and the current flowing through the neutral line is also very large, especially in rural areas. , since the down line is generally single-phase access, the imbalance is more serious. [0003] One of the direct impacts caused by the three-phase imbalance in the station area is the unbalance of the three-phase voltage at the end. Due to the large current flowing on the zero line, the voltage drop is relatively large, and the neutral point of the end user has shifted, causing some phase voltages to be too high, the insulation of the use...

AI Technical Summary

Problems solved by technology

Due to the large current flowing on the zero line, the voltage drop is relatively large, and the neutral point of the end user has shifted, causing some phase voltages to be too high, the insulation of the user's electrical appliances is aging, and the service life is reduced; some phase user voltages are too low, some The electrical appliance cannot be started, which directly affects the user's experience of using electricity

[0004] Another problem caused by three-phase imbalance is the increase of line loss in the station area

However, the topological structure of the distribution low-voltage station area is complex, and the size of the user's power consumption load and the power consumption time are inconsistent, so that the simple collection of each user's power data cannot reflect the characteristics of the user's load and power consumption time; and for each user installation One load data collection device requires too many devices to be installed, which reduces the efficiency of load data collection in the station area
