Description

一种基于GPRS远程监控的光伏发电***
技术领域
本实用新型涉及一种光伏发电***，具体涉及一种基于GPRS远程监控的光伏发电***。
背景技术
以太阳能、风能为代表的大规模可再生能源并网发电已经成为新型电力***不可阻挡的发展趋势。然而太阳能、风能本身所固有的波动性和间歇性为发电***带来了巨大挑战，因此如何对光伏发电***进行实时监控，主动发现光伏发电***的问题，及时安排检修，是十分重要的。
光伏发电***远程监控可以分为有线远程监控和无线远程监控，有线远程监控的缺点是距离有限，如果在偏远地区安装光伏发电***，就无法实现有线远程监控。
发明内容
本实用新型的目的在于克服上述现有技术的不足，提供一种基于GPRS远程监控的光伏发电***，该光伏发电***采用的GPRS传输具有更远的覆盖、更宽的范围、实时性好、移动、通信成本低的特点。
为实现上述目的，本实用新型采用的技术方案是：一种基于GPRS远程监控的光伏发电***包括信号采集单元、发电***执行单元、无线通讯单元和发电***控制单元，其中所述信号采集单元包括光伏电池单元、光照传感器、温度传感器、电压传感器和电压采样模块，所述发电***执行单元包括DC/DC变换器、DC/AC逆变器、驱动模块和交流负载，所述无线通讯单元包括RS232C通信接口、GPRS模块、Internet网络和监控中心，所述发电***控制单元包括DSP控制器、报警器、显示器、存储模块、电源模块和混合储能模块，所述光伏电池单元分别与光照传感器、温度传感器和电压传感器相连，所述电压传感器与电压采样模块相连，所述DC/DC变换器和DC/AC逆变器与驱动模块相连，所述DC/AC逆变器与交流负载相连，所述RS232C通信接口通过GPRS模块和Internet网络与监控中心连接，所述光照传感器、温度传感器、电压采样模块、驱动模块、RS232C通信接口、报警器、显示器、存储模块、电源模块和混合储能模块与DSP控制器相连。混合储能模块是由超级大电容和蓄电池组成，蓄电池是当前最常用的储能单元，但由于其单体造价高，使用次数有限制，且单一的储能单元无法同时满足***对功率与能量的要求，所以本文采用超级电容与蓄电池组成的混合储能***，以满足***运行的电能质量要求和负荷的功率需求。常规的电容储能单元在***运行时，如果功率需求发生变化，超级电容器优先动作补偿功率缺额，但由于超级电容本身能量密度较小，其输出功率越大或输出时间越长时，超级电容的能量越容易达到最大/最小限值，所以超级电容不能长时间对储能***输出功率进行控制，而混合储能将暂时由超级电容承担的负荷缺额逐步转移给蓄电池，由蓄电池来承担功率缺额的补偿，此混合储能单元改善了***运行的电能质量要求，也最大限度地满足了负荷的功率需求，同时优化了蓄电池的工作过程，延长了蓄电池使用寿命。
本实用新型由于采用了以上技术方案，具有显著的技术效果：一种基于GPRS远程监控的光伏发电***能够监控整个***的运行状态，设备的各个参数，记录***的发电量，并对故障进行报警。通过电脑终端显示，可实现实时监控相关数据，符合智能电网对各接入电源调控的要求，便于推广使用。
