基于Scott变压器的两相平衡供电装置与控制方法
Two-phase balanced power supply equipment and control method based on Scott transformer
摘要
Abstract
In rural low-voltage power grids,the load from traditional household appliances is relatively light,and electricity usage periods largely overlap,which has a limited impact on the three-phase imbalance in distribution transformers.The key factor contributing to three-phase imbalance in these transformers is the presence of some large single-phase production loads such as household tea stir-frying machines,oil pressers,and fruit sorting machines commonly found in rural areas of Jiangxi Province.Addressing the imbalance problems caused by these large single-phase production loads in the low-voltage grid means solving the three-phase imbalance problem in rural distribution transformers to a great extent.This paper propo-ses a two-phase balanced power supply device and its control method suitable for this situation.By utilizing the two-phase balancing characteristics of the Scott transformer for power supply,the imbalance caused by single-phase and two-phase loads on the three-phase system of the distribution transformer is effectively reduced.Furthermore,by integrating a compen-sation converter,full three-phase power balance for two-phase loads is achieved with a relatively small capacity.Finally,sim-ulations and experiments verify the effectiveness of the balancing control method of the proposed device.关键词
