产品概述Product Brief
The static reactive power generator SVG adopts a power-electronic device (IGBT) that can be turned off to form a self-commutated bridge circuit, connected in parallel to the power grid through a reactor, and appropriately adjusts the amplitude and phase of the output voltage of the AC side of the bridge circuit, or directly Control its AC side current. Quickly absorb or emit the required reactive power to achieve the purpose of quickly and dynamically adjusting reactive power. As an active compensation device, it can not only track the inrush current of the impact load, but also track and compensate the harmonic current.
静止无功发生器SVG采用可关断电力电子器件（IGBT）组成自换相桥式电路，经过电抗器并联在电网上，适当地调节桥式电路交流侧输出电压的幅值和相位，或者直接控制其交流侧电流。迅速吸收或者发出所需的无功功率，实现快速动态调节无功的目的。作为有源型补偿装置，不仅可以跟踪冲击型负载的冲击电流，而且可以对谐波电流也进行跟踪补偿。

注Note：
无源单组的补偿容量一定要小于有源的补偿容量，才可达到细补的要求。
The compensation capacity of the passive single group must be smaller than the active compensation capacity to meet the requirements of fine compensation.

无功补偿容量选型：一般按照变压器容量的30%进行选型，例如变压器容量为1250KVA，则需要配备375Kvar的无功补偿，混补模式可配备75Kvar有源+300Kvar的无源（注：无源每组的补偿容量一定要小于有源的补偿容量，才可达到细补的要求。）
Reactive compensation capacity selection: Generally, the selection is based on 30% of the transformer capacity. For example, the transformer capacity is 1250KVA, then 375Kvar reactive power compensation is required, and the mixed compensation mode can be equipped with 75Kvar active + 300Kvar passive (Note: None The compensation capacity of each source group must be smaller than the active compensation capacity to meet the requirements of fine compensation.)
