  “十四五”期间,随着“双碳”目标提出及逐步落实,本就呈现出较好发展势头的分布式光伏发展有望大幅提速。就“十四五”光伏发展规划,国家发改委能源研究所可再生能源发展中心副主任陶冶表示,“双碳”目标意味着国家产业结构的调整,未来10年,新能源装机将保持在110GW以上的年增速,这里面包含集中式光伏电站和分布式光伏电站。相较于集中式电站来说,分布式对土地等自然资源没有依赖,各个地方的屋顶就是分布式电站的形成基础,在碳中和方案的可选项中,分布式光伏由于其灵活性必将被大力发展,目前已有河北、甘肃、安徽、浙江、陕西等9省发布关于分布式光伏整县推进工作的通知。

  目前我国的两种分布式应用场景分别是:广大农村屋顶的户用光伏和工商业企业屋顶光伏,这两类分布式光伏电站今年都发展迅速。

  10)故障报警

  当电池板长时间输出功率偏低进行故障指示,建议运维人员前往现场检查是否有故障发生等;另外对于并网柜部分的主断路器分合闸状态进行监视,当出现开关变位及时报警,提醒运维人员。

1.1 交流220V并网
交流220V并网的光伏发电系统多用于居民屋顶光伏发电,装机功率在8kW左右。户用光伏电站今年发展非常迅猛,根据国家能源局网站提供的数据,截至2021年6月底,全国累计纳入2021年国家财政补贴规模户用光伏项目装机容量为586.14万千瓦,这相当于6个月在居民屋顶建造了四分之一个三峡水电站。

部分小型光伏电站为自发自用,余电不上网模式,这种类型的光伏电站需要安装防逆流保护装置,避免往电网输送电能。光伏电站规模较小,而且比较分散,对于光伏电站的管理者来说,通过云平台来管理此类光伏电站非常有必要,安科瑞在这类光伏电站提供的解决方案包括以下方面:
 
1.2 交流380V并网
根据国家电网Q/GDW1480-2015 《分布式电源接入电网技术规定》,8kW~400kW可380V并网,超出400kW的光伏电站视情况也可以采用多点380V并网,以当地电力部门的审批意见为准。这类分布式光伏多为工商业企业屋顶光伏,自发自用,余电上网。分布式光伏接入配电网前,应明确计量点,计量点设置除应考虑产权分界点外,还应考虑分布式电源出口与用户自用电线路处。每个计量点均应装设双向电能计量装置,其设备配置和技术要求符合 DL/T 448 的相关规定,以及相关标准、规程要求。电能表采用智能电能表,技术性能应满足国家电网公司关于智能电能表的相关标准。用于结算和考核的分布式电源计量装置,应安装采集设备,接入用电信息采集系统,实现用电信息的远程自动采集。

光伏阵列接入组串式光伏逆变器,或者通过汇流箱接入逆变器,然后接入企业380V电网,实现自发自用,余电上网。在380V并网点前需要安装计量电表用于计量光伏发电量,同时在企业电网和公共电网连接处也需要安装双向计量电表,用于计量企业上网电量,数据均应上传供电部门用电信息采集系统,用于光伏发电补贴和上网电量结算。
部分光伏电站并网点需要监测并网点电能质量,包括电源频率、电源电压的大小、电压不平衡、电压骤升/骤降/中断、快速电压变化、谐波/间谐波 THD、闪变等,需要安装单独的电能质量监测装置。部分光伏电站为自发自用,余电不上网模式,这种类型的光伏电站需要安装防逆流保护装置,避免往电网输送电能。
这种并网模式单体光伏电站规模适中,可通过云平台采用光伏发电数据和储能系统运行数据,安科瑞在这类光伏电站提供的解决方案包括以下方面:
  
 
1.3 10kV或35kV并网
根据《国家能源局关于2019年风电、光伏发电项目建设有关事项通知》(国发新能〔2019〕49号),对于需要国家补贴的新建工商业分布式光伏发电项目,需要满足单点并网装机容量小于6兆瓦且为非户用的要求,支持在符合电网运行安全技术要求的前提下,通过内部多点接入配电系统。
此类分布式光伏装机容量一般比较大,需要通过升压变压器升压后接入电网。由于装机容量较大,可能对公共电网造成比较大的干扰,因此供电部门对于此规模的分布式光伏电站稳控系统、电能质量以及和调度的通信要求都比较高。
光伏电站并网点需要监测并网点电能质量,包括电源频率、电源电压的大小、电压不平衡、电压骤升/骤降/中断、快速电压变化、谐波/间谐波 THD、闪变等,需要安装单独的电能质量监测装置。

上图为一个1MW分布式光伏电站的示意图,光伏阵列接入光伏汇流箱,经过直流柜汇流后接入集中式逆变器(直流柜根据情况可不设置),最后经过升压变压器升压至10kV或35kV后并入中压电网。由于光伏电站装机容量比较大,涉及到的保护和测控设备比较多,主要如下表:
