Abstract

The invention discloses a low voltage reactive compensation device and a low voltage reactive compensation system. The low voltage reactive compensation device comprises main switches (3), a star-shaped unbalanced capacitance compensation circuit (4) and an angular balance capacitance compensation circuit (5). The angular balance capacitance compensation circuit (5) is connected with A phase, B phase and C phase of three-phase alternating current through three main switches (3). One end of the star-shaped unbalanced capacitance compensation circuit (4) is connected with A phase, B phase and C phase of three-phase alternating current through three main switches (3). The other end is connected with a zero line. According to the low voltage reactive compensation device and the low voltage reactive compensation system, the problem of substandard electrical energy delivery in the prior art is overcome, and substandard electrical energy reactive compensation is realized.

Description

technical field [0001] The invention relates to the field of intelligent high-precision low-voltage reactive power compensation, in particular to a low-voltage reactive power compensation device and a low-voltage reactive power compensation system using the device. Background technique [0002] At present, my country's urban residents and commercial electricity use the 400V power grid (including the rural power grid) system, which is mainly converted from the voltage through the 10KV power transmission system, and there are often several or even twenty or thirty units connected to one line. Distribution transformers of various sizes. However, with the development of social economy and the improvement of people's living standards. Inevitably, on the one hand, the electricity consumption of residents in the same area has increased significantly, which has prompted the need to increase the capacity of public substations in the original area. On the other hand, due to the large...
