集中式逆变器和组串式逆变器之比较
集中式逆变器和组串式逆变器之比较——深圳恒通源1、逆变器方案对比（1）集中式逆变器：设备功率在50KW到630KW之间，功率器件采用大电流IGBT，系统拓扑结构采用DC-AC一级电力电子器件变换全桥逆变，工频隔离变压器的方式，防护等级一般为IP20。
体积较大，室内立式安装。
（2）组串式逆变器：功率小于30KW，功率开关管采用小电流的MOSFET，拓扑结构采用DC-DC-BOOST升压和DC-AC全桥逆变两级电力电子器件变换，防护等级一般为IP65。
体积较小，可室外臂挂式安装。
2、系统主要器件对比（1）集中式逆变器：光伏组件，直流电缆，汇流箱，直流电缆，直流汇流配电，直流电缆，逆变器，隔离变压器，交流配电，电网。
（2）组串式逆变器：组件，直流电缆，逆变器，交流配电，电网。
3、主要优缺点和适应场合（1）集中式逆变器一般用于日照均匀的大型厂房，荒漠电站，地面电站等大型发电系统中，系统总功率大，一般是兆瓦级以上。
主要优势有：●逆变器数量少，便于管理；●逆变器元器件数量少，可靠性高；●谐波含量少，直流分量少电能质量高；●逆变器集成度高，功率密度大，成本低；●逆变器各种保护功能齐全，电站安全性高；●有功率因素调节功能和低电压穿越功能，电网调节性好。
主要缺点有：●直流汇流箱故障率较高，影响整个系统。
●集中式逆变器MPPT电压范围窄，一般为450-820V，组件配置不灵活。
在阴雨天，雾气多的部区，发电时间短。
●逆变器机房安装部署困难、需要专用的机房和设备。
●逆变器自身耗电以及机房通风散热耗电，系统维护相对复杂。
●集中式并网逆变系统中，组件方阵经过两次汇流到达逆变器，逆变器最大功率跟踪功能（MPPT）不能监控到每一路组件的运行情况，因此不可能使每一路组件都处于最佳工作点，当有一块组件发生故障或者被阴影遮挡，会影响整个系统的发电效率。
●集中式并网逆变系统中无冗余能力，如有发生故障停机，整个系统将停止发电。

组串式逆变器原理
组串式逆变器原理组串式逆变器是太阳能发电系统中常见的一种逆变器类型，它能够将太阳能光伏电池板所产生的直流电转换为交流电，以供给家庭或工业用电。
在太阳能发电系统中，组串式逆变器扮演着至关重要的角色，因此了解其原理对于太阳能发电系统的设计和运行至关重要。
组串式逆变器的原理可以分为以下几个方面进行介绍：1. 输入端电压匹配。
组串式逆变器的输入端通常连接多块太阳能光伏电池板，这些电池板产生的直流电压会有所不同。
而组串式逆变器需要将这些不同的直流电压转换为统一的交流电压输出。
因此，组串式逆变器需要具备电压匹配功能，能够根据输入端的电压情况进行调整，以确保输出的交流电压稳定和符合要求。
2. MPPT 最大功率点跟踪。
太阳能光伏电池板的输出功率会受到光照强度和温度等因素的影响，因此其输出电压和电流也会随之变化。
组串式逆变器需要具备 MPPT（最大功率点跟踪）功能，能够实时跟踪太阳能光伏电池板的最大输出功率点，以确保系统能够以最高效率工作。
3. 电流保护和隔离。
在太阳能发电系统中，由于光照条件的不同，光伏电池板的输出电流也会有所变化。
组串式逆变器需要具备电流保护功能，能够对输入端的电流进行监测和保护，以避免过载和短路等情况的发生。
同时，组串式逆变器还需要具备隔离功能，能够确保系统的安全运行。
4. 输出端电压稳定。
组串式逆变器的输出端需要输出稳定的交流电压，以供给家庭或工业用电。
因此，组串式逆变器需要具备输出端电压稳定功能，能够对输出端的电压进行调整和控制，以确保输出的电压稳定在所需范围内。
5. 效率和可靠性。
组串式逆变器需要具备高效率和可靠性，能够将太阳能光伏电池板的直流电转换为高质量的交流电输出。
同时，组串式逆变器还需要具备良好的散热和防尘功能，以确保其在各种环境条件下都能够稳定运行。
总之，组串式逆变器作为太阳能发电系统中的重要组成部分，其原理涉及到电压匹配、最大功率点跟踪、电流保护和隔离、输出端电压稳定、效率和可靠性等多个方面。

组串式逆变器工作原理
组串式逆变器工作原理
？
汇流组串式逆变器是一种新型的小型逆变器，它可以将直流电压转换为交流电压，并能够调节电压大小，使用容易，对外形要求低，运行稳定。
汇流组串式逆变器由汇流支路、桥式调节电路、PWM模式控制和变压开关等零部件组成。
首先，将DC直流电源经过汇流，使两侧的电压差小于额定电压，再通过桥式调节电路的晶闸管，实现可控制的半波整流，产生交流电压。
然后，将交流电压输入到变压开关芯片，芯片内的PWM模式控制模块实现电压的调节，最后，通过反馈控制系统调节变压开关模块，实现输出电压的调节，使输出电压和额定电压更接近。
汇流组串式逆变器具有可靠性高、工作稳定、体积小、使用成本低等优点，是当前微型逆变器中的佼佼者。
它可用于光伏逆变器、汽车充电及各种小型电子电源的转换。
汇流组串式逆变器的应用可以使绿色能源、新能源的应用和发展变得更加快捷、便捷，可以带来更多的经济效益和社会效益，有助于推动我国电力工程的发展。
