??1.產(chǎn)品概述 / Product Overview
??工業(yè)級(jí)全效電能質(zhì)量模塊ASVG是將APF與SVG功能集于一體，充分利用了APF的諧波濾除功能，同時(shí)又利用了SVG的無(wú)功補(bǔ)償功能。ASVG根據(jù)CT采集負(fù)載電流，通過(guò)離散傅里葉變換與帕克變換分別提取諧波、無(wú)功、不平衡電流等待補(bǔ)償分量，通過(guò)整流器電路產(chǎn)生與待補(bǔ)償成分大小相等相位相反的電流，將系統(tǒng)電流補(bǔ)償為T(mén)HD、PF、不平衡度都滿足指標(biāo)的質(zhì)優(yōu)電流。
??Industrial-grade full-efficiency power quality module ASVG integrates APF and SVG functions into a whole, making full use of APF's harmonic filtering function and SVG's reactive compensation function. ASVG collects the load current through CT, extracts the harmonic current, reactive current and unbalanced current respectively through Discrete Fourier Transformation and Park transformation to wait for compensation components, generates the current equal to the component to be compensated and opposite in phase through the rectifier circuit, and compensates the system current to be high quality current with THD, PF and imbalance meeting indexes.
??2.工作原理 / Operating Principle
??? 諧波電流濾除原理
??? Principle of harmonic current filtering
??ASVG通過(guò)外部系統(tǒng)電流互感器實(shí)時(shí)采集電流信號(hào)，控制器分離出其中的諧波電流部分， IGBT功率變換器產(chǎn)生與系統(tǒng)中的諧波大小相等相位相反的補(bǔ)償電流，實(shí)現(xiàn)濾除系統(tǒng)諧波電流的功能。
??ASVG collects the current signal through the current transformer of the external system in real time, the controller separates the harmonic current, and IGBT power converter generates the compensation current equal to the harmonic in the system and opposite in phase, so as to filter the harmonic current of the system.
??ASVG輸出補(bǔ)償電流根據(jù)系統(tǒng)電流的諧波量變化而動(dòng)態(tài)變化。另外，ASVG有限流功能，當(dāng)系統(tǒng)的需補(bǔ)償?shù)闹C波量大于ASVG容量時(shí)，ASVG可以限制在100%額定容量輸出，不會(huì)發(fā)生過(guò)載。
??ASVG output compensation current changes dynamically with the harmonic content of the system current. In addition, ASVG has advanced current limiting function. When the harmonic content to be compensated is greater than ASVG capacity, ASVG can be limited to 100% rated capacity output without overload.

??ASVG collects the current signal through the current transformer of the external system in real time, the controller separates the reactive current, and IGBT power converter generates the compensation current equal to the reactive current in the system and opposite in phase, so as to realize the function of reactive compensation.
??補(bǔ)償目標(biāo)功率因數(shù)可以通過(guò)用戶界面設(shè)定，ASVG不會(huì)出現(xiàn)過(guò)補(bǔ)或者欠補(bǔ)，并且補(bǔ)償電流平滑，不會(huì)對(duì)負(fù)載和電網(wǎng)產(chǎn)生涌流沖擊。
??The compensation target power factor can be set through the user interface. ASVG will not overcompensate or undercompensate, and the compensation current will be smooth, having no inrush current impact on the load and the power grid.
