Problems solved by technology

[0002] In reactive power compensation, the compensation accuracy reflects the efficiency of effective compensation. Low compensation accuracy will cause under-compensation or over-compensation, and a large amount of power will be consumed in this process, which will reduce the efficiency of effective compensation. When the load is relatively stable , its effect is particularly obvious; and can increase the capacity load
[0003] Reactive power compensation devices are usually used for reactive power compensation outdoors, coupled with large power consumption, so there is an urgent need for a reactive power compensation device with high protection efficiency and high compensation accuracy, and can achieve long-term outdoor reactive power compensation
[0004] Reactive power compensation devices in the prior art generally use surge protectors for surge protection to improve the safety of reactive power compensation devices, but their protection limits are small and cannot be applied to the needs of outdoor reactive power compensation

Abstract

The invention provides a reactive power compensation device with a redundant power supply. Data acquired by a current transformer is analyzed and compared by setting a reactive power compensation controller; a composite switch and a micro circuit breaker are adjusted to form a feedback loop. While the reaction speed is guaranteed, the surge protection efficiency of the reactive power compensation device is improved, and the safety coefficient of the reactive power compensation device is greatly improved; while surge protection is adjusted, the compensation precision and the capacity load increasing amount of the reactive power compensation device are improved; due to the fact that power supply redundancy is increased, when the electric quantity of one power module is used up or the power module fails, a redundant power module can substitute the power module, the electric energy reserves are higher, the safety coefficient is higher, and the reactive power compensation device can be more adaptive to outdoor long-tern reactive power compensation.

Description

technical field [0001] The invention relates to the field of reactive power compensation, in particular to a reactive power compensation device with redundant power supply. Background technique [0002] In reactive power compensation, the compensation accuracy reflects the efficiency of effective compensation. Low compensation accuracy will cause under-compensation or over-compensation, and a large amount of power will be consumed in this process, which will reduce the efficiency of effective compensation. When the load is relatively stable , its influence is particularly obvious; and can increase the capacity load. [0003] Reactive power compensation devices are usually used outdoors for reactive power compensation. In addition, the power consumption is large. Therefore, a reactive power compensation device with high protection efficiency and high compensation accuracy is urgently needed, and can realize reactive power compensation outdoors for a long time. [0004] React...
