Description

光伏电站生活用电自备电系统
技术领域
本实用新型涉及一种光伏电站生活用电自备电系统。
背景技术
近几年，我国新能源持续快速增长，风电、太阳能发电新增装机容量创新高，光伏装机容量首次超过德国跃居世界第一，在能源结构优化和绿色发展转型中发挥重要作用，成为我国新能源发展史上新的里程碑。然而，随着新能源开发与市场不匹配、跨省跨区输电通道不足、电源结构不合理、政策机制不健全等原因，部分地区出现严重的弃风弃光现象。在这种严峻的弃光状态下，亟需在光伏电站运维中开创出一种实用型提质增效方案，有效降低电站运维成本，实现降本增效，效益最大化。
实用新型内容
本实用新型的目的是提供一种光伏电站生活用电自备电系统，能够显著节约光伏电站生活用电的电费，从而大大降低了电站运维的成本。
一种光伏电站生活用电自备电系统，其特别之处在于：包括蓄电池组，该蓄电池组依次通过时控开关、稳压整流装置与光伏组件汇流箱直流断路器出口连接，并且该蓄电池组还依次通过逆变器、隔离变压器接自动转换开关的一路输入端，该自动转换开关的另一路输入端接站用变或市电，而该自动转换开关的输出端接负载从而提供光伏电站生活用电。
其中在时控开关旁还串联有防接反装置，从而阻止蓄电池组向光伏组件汇流箱送电。
其中防接反装置采用MOS管型防接反保护电路。
本实用新型的有益效果是：1、在严峻的限电情况下，本实用新型系统带有储电功能，将白天无法外送的多余电量收集起来，代替市电供夜间生活用电。2、在不限电的情况下，利用低功率组件(旧组件)改接此装置，代替市电供电，有效的降低光伏电站自用电成本，实现降本增效。本实用新型的技术方案投资较小，只需要增加逆变器、蓄电池、变压器、充放电控制器、稳压整流装置、双电源切换开关、部分线路和空气开关，且逆变器、变压器的容量较小，价格也较低，回路设计简单，技术难度较小。经过测算，前期投资约16万元，投入后，一年的电费可省下约11万元，大大降低了电站运维的成本。
附图说明
附图1为本实用新型的电路原理图。
具体实施方式
如图1所示，本实用新型提供了一种光伏电站生活用电自备电系统，包括蓄电池组，该蓄电池组依次通过时控开关K、稳压整流装置(稳压整流器)与光伏组件汇流箱直流断路器出口连接，并且该蓄电池组还依次通过逆变器、隔离变压器GB接自动转换开关ATS的一路输入端，该自动转换开关ATS的另一路输入端接市电，而该自动转换开关ATS的输出端接负载从而提供光伏电站生活用电。其中在时控开关K旁还串联有防接反装置(具体采用MOS管型防接反保护电路装置)，从而阻止蓄电池组向光伏组件汇流箱送电。
实施例1：
所需设备名称：12V200AH蓄电池32块、稳压整流装置一台、逆变器带隔离变压器GB一套(变压器容量56KVA)、自动转换开关ATS一个、时控开关K一个。
本实用新型的使用方法和工作原理如下：
从光伏组件汇流箱直流断路器出口接一组直流电到蓄电池，白天对蓄电池组进行充电，夜间(晚上18点至次日早上8点)时，时控开关K作用，断开光伏组件，蓄电池组通过逆变器、隔离变压器GB、自动转换开关ATS供光伏电站生活用电。
整个回路采用双电源设计，在阴雨天蓄电池未充满的情况下，通过自动转换开关ATS可以使用市电供给光伏电站生活用电。
蓄电池可以正常工作时，优先使用蓄电池组，因生活用电使用的是三相四线制供电方式，因此逆变器后装设一台三相变压器，以满足回路配电的技术要求，汇流箱到蓄电池组安装防接反装置，防止夜间不发电时，蓄电池通过汇流箱反送电。
