產(chǎn)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.
靜止無功發(fā)生器SVG采用可關(guān)斷電力電子器件（IGBT）組成自換相橋式電路，經(jīng)過電抗器并聯(lián)在電網(wǎng)上，適當(dāng)?shù)卣{(diào)節(jié)橋式電路交流側(cè)輸出電壓的幅值和相位，或者直接控制其交流側(cè)電流。迅速吸收或者發(fā)出所需的無功功率，實(shí)現(xiàn)快速動(dòng)態(tài)調(diào)節(jié)無功的目的。作為有源型補(bǔ)償裝置，不僅可以跟蹤沖擊型負(fù)載的沖擊電流，而且可以對(duì)諧波電流也進(jìn)行跟蹤補(bǔ)償。

注Note：
無源單組的補(bǔ)償容量一定要小于有源的補(bǔ)償容量，才可達(dá)到細(xì)補(bǔ)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.

無功補(bǔ)償容量選型：一般按照變壓器容量的30%進(jìn)行選型，例如變壓器容量為1250KVA，則需要配備375Kvar的無功補(bǔ)償，混補(bǔ)模式可配備75Kvar有源+300Kvar的無源（注：無源每組的補(bǔ)償容量一定要小于有源的補(bǔ)償容量，才可達(dá)到細(xì)補(bǔ)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.)
