Description

一种光伏变电站监控系统
技术领域
本发明属于光伏变电站技术领域，具体涉及一种光伏变电站监控系统。
背景技术
近年来，随着计算机技术、互联网技术的应用和普及，越来越多先进技术应用使得电力工业得到了很大的发展，电网规模不断扩大，电力设备日益增多，需要监控的信息量日益增多，对变电站监控设备及应急维护提出了更高的要求，而现有电网调度自动化监控设备都不能适应日益发展变化的需求，这主要表现在：以前的电力监控设备主要依赖于局域网技术为后台管理平台提供信息；已有的电力监控设备中，其供电模块单一。以上这些缺点对电网的扩展，监察和控制造成了很大的限制。
另一方面太阳能作为一种新能源，取之不尽，用之不竭，是一种洁净的能源，在开发利用时，不会产生废渣、废水、废气、也没有噪音，更不会影响生态平衡，绝对不会造成污染和公害，因此在提倡环保的今天，广为被人们所青睐。光伏发电，其基本原理就是“光伏效应”，受光照强度的影响较大，目前的光伏发电通常直接驱动用电电机，经常造成用电电机的频繁启动，并且，在夜间光伏发电的能力有限，导致用电设备停止工作，严重影响工作效率，而采用手工的方式切换交流电源，则浪费人力且无法准确的把握时间。
发明内容
本发明的目的是提供一种光伏变电站监控系统，杜绝因为人员责任心和业务水平不足造成的巡视不到位，保障无人值班变电站安全可靠运行。
本发明提供了如下的技术方案：
一种光伏变电站监控系统，包括光伏发电输出模块、GPRS通信模块和上位机，所述光伏发电输出模块包括光伏控制模块以及与所述光伏控制模块连接的逆变器模块和光伏组件模块，所述光伏控制模块连接所述GPRS通信模块，所述GPRS通信模块连接所述上位机。
优选的，所述光伏发电输出模块还包括充放电控制模块，所述充放电控制模块连接所述光伏组件模块，所述充放电控制模块连接有蓄电池模块。
优选的，所述蓄电池模块包括相互连接的充电保护电路和蓄电池组，所述充电保护电路连接所述充放电控制模块。
优选的，所述上位机还分别连接有用户手持设备和开出单元，所述开出单元用于依据所述上位机的指令进行开关量输出，所述开出单元的输出端分别与光伏发电设备和变电站中的部件连接。
本发明的有益效果是：基于GPRS通信的节能环保无线远程变电站监控系统的电力来源为光伏发电技术与市电相结合，将光能转化的电能为系统提供所需电能，缓解了能源压力，降低了污染达到了节能环保的效果，同时停电后能提供备用电源，增加了系统的抗风险性，另一方面采用的安全保护模块能够在负载发生异常或者人为需要时及时自动断开电流输出，最大程度的保护了人身财产安全。
