Description

technical field

[0001] The invention relates to the technical field of electric low-voltage distribution network, in particular to a low-voltage dynamic reactive power compensation device for capacitors. Background technique

[0002] As a large number of non-linear loads such as modern power electronic equipment are connected to the power grid, the power supply quality of the power grid is seriously affected. Among them, a large number of applications of various power electronic switching devices and frequent fluctuations in loads are the main sources of interference, resulting in a series of bad influences. Grid voltage quality is usually measured by indicators such as stability, symmetry and sine.

[0003] 1. With the increase of nonlinear loads such as frequency converters, electric welding machines, and switching power supplies, the amount of harmonics generated in the power supply and distribution system is relatively large.

[0004] 2. In the capacitance compensation...
