Description

太阳能光伏微网发电***
技术领域
本实用新型涉及一种光伏发电***，具体地说是一种太阳能光伏微网发电***，属于光伏发电领域。
背景技术
太阳能光伏发电是太阳能开发利用的重要方式，目前太阳能发电主要包括离网型发电***和并网型发电***。离网型发电***解决了偏远地区或电力供应不发达地区的供电，但离网型***过多地依赖蓄电池，***效率低，投资成本高，并且随着国家电网的发展，离网***面临报废的处境。光伏并网发电***效率高，投资成本低，通过电价差价取得光伏并网***经济效益。然而，目前的光伏并网发电***均为5MW及以上光伏并网发电***，中小功率等级的光伏并网发电***成本高、效率低、不利于推广。同时，由于太阳能光伏电站受环境因素影响比较大，监控的广度、精度、实时性、投切速度要求非常高。如何通过整合资源提高光伏微网发电***供电的安全性和可靠性，有效提升配电网防止外力破坏和防灾抗灾的能力，已成为新的研究课题。
实用新型内容
为了解决上述问题，本实用新型设计了一种太阳能光伏微网发电***，结合了并网型光伏发电技术和离网光伏发电技术的优点，解决了当前中小功率太阳能光伏发电的成本高、效率低的问题。
本实用新型的技术方案为：
一种太阳能光伏微网发电***，所述***由依次相连的太阳能电池板、微网变流器、蓄电池充放电设备、蓄电池组及蓄电池管理***组成，所述微网变流器与配电柜相连，所述配电柜分别与负载及公共电网相连；所述微网变流器由前后两级构成，前级负责太阳能电池板最大功率点跟踪工作；后级实现直流电能到交流电能的转换。
所述蓄电池管理***为微网发电***提供蓄电池组状态信息。
进一步地，所述配电柜设有测量控制单元，所述测量控制单元通过无线通信模块经过无线通信网络与监控主站相连。所述测量控制单元采集光伏微网发电***的环境参数和***参数数据存储并处理，然后通过无线通信模块将数据经无线通信网络传送到监控主站，监控主站收到信息后进行智能分析和决策，通过无线通信网络经无线通信模块下达到测量控制单元。所述监控主站设有WEB后台，所述监控主站将从测量控制单元传递来的信息通过WEB后台发布到Internet，从而实现远程实时监控。
进一步地，所述无线通信模块为3G无线通信模块，所述无线通信网络为3G无线通信网络。另外，还无线通信可以是UWB等方式。
进一步地，所述负载分为一般负载和重要负载两部分。
进一步地，所述蓄电池组由如干蓄电池串联而成，每个蓄电池均设有壳体和密封盖，所述的壳体与密封盖之间设有密封防水胶圈，防水性能好，使用寿命长。
电网正常时，***首先要保证蓄电池具备一定的电量，以备电网停电时应急使用。之后，在太阳能电池板最大功率范围允许之内，尽量提供负责所需能量，但不超过负载功率需求，多于部分存到蓄电池中。在太阳能电池板功率不足时，将蓄电池存储的能量提供给负载。微网发电装置因故停机时，由公共电网通过配电柜直接向负载供电；微网供电***正常，公共电网停电，重要负载与公共电网脱离，由微网变流器直接向负载供电。
本实用新型的优点在于：结合了并网型光伏发电技术和离网光伏发电技术的优点，解决了当前中小功率太阳能光伏发电的成本高、效率低的问题，而且还能够实时监控周围环境及设备运行参数，并可通过无线网络实现远程监控，监控准确率高，速度快。
