Abstract

The invention discloses a three-phase imbalance control method, system and equipment based on load data, and the method comprises the steps: firstly, naming each branch line and load of a transformer area to obtain the label of each branch line and load, obtaining the levels of the branch lines and load in the transformer area through the labels, then calculating the average line loss amount of each branch line and the average power consumption amount of the load, and then, according to the average line loss amount, the average power consumption of the load and the labels of the branch lines and the load, generating an action priority matrix of the phase-change switches in the branch lines, and when the three-phase unbalance degree at the outlet of the transformer in the transformer area is detected, performing action on the specific phase-change switches according to the action priority matrix, so that the phase-change switches are switched on or switched off. Therefore, the balance degree of each item is adjusted, and the adjustment process is continuously circulated until three phases are balanced. Therefore, the technical problems of limited loss reduction effect and low efficiency in the prior art are solved.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a load data-based three-phase unbalance control method, system and equipment. Background technique [0002] In the entire power network, any link of generation, transmission, distribution, and delivery will generate energy loss. Among them, the low-voltage distribution network directly connected to users has a wide coverage, many distribution equipment, complex and dense lines, and the loss of the low-voltage distribution network accounts for more than 60% of the total loss of the power grid. The unbalanced three-phase load in the distribution network will cause unbalanced current in the system, which will cause more active power loss of transformers and lines under unbalanced operation state, reduce the output capacity of transformers, and reduce the quality of power supply and other adverse consequences. How to technically reduce losses at the distribution ne...
