Description

technical field [0001] The invention relates to the technical field of dynamic reactive power compensation equipment for power quality control, in particular to a fast-response self-excited magnetic control reactor. Background technique [0002] The well-known magnetic valve type controllable reactor is referred to as a magnetic control reactor, which is a dynamic reactive power compensation device designed to work in a magnetic saturation state based on the principle of a magnetic amplifier. A magnetic valve with a slightly smaller area is set in its main core, and the DC bias is used to adjust the magnetic flux passing through the magnetic valve, thereby changing the saturation of the magnetic valve, thereby changing the output current of the reactor, and finally realizing the controllable capacity adjust. Because the controllable reactor with this working principle has obvious advantages such as simple maintenance, stable operation, high cost performance, and continuous ...

Problems solved by technology

[0003] However, with the increasing complexity of the grid load, the system has higher requirements for the response speed of dynamic reactive power compensation

Therefore, various quick improvement measures of self-excited magnetron reactors have also been studied in the prior art. Although there is a certain improvement effect, the corresponding circuit structure and control strategy become extremely complicated.

In particular, most of the measures adopt the method of increasing DC bias voltage or compound excitation, and it is necessary to provide a set of independent excitation sources, which not only greatly increases the investment cost and floor area, but also increases the difficulty of on-site process control.
