Description

一种基于OPPC线的配电网自动化传输系统及方法
技术领域
本发明涉及配电网技术领域，具体地说是一种基于OPPC线的配电网自动化传输系统及方法。
背景技术
箱式变电站应用于城区电建、工矿企业等地。箱式变电站布局分散，若现场监控布线，投入巨大，设施维护很不方便，目前，箱变安全监管工作多采用人工定期巡查、定期维护管理机制，占用人工较多，巡查质量不高，故障发生时也不能及时得到反应。
对于箱变远程监控技术，现有基于GPRS的监控系统设计方案，虽然GPRS无须布线，可实现24小时在线的远程通信，但是GPRS通信受恶劣天气影响大，也容易因数据量大而造成信息堵塞。现有基于IEC61850标准的嵌入式以太网箱变监控系统，可以实现电压电流、环境温湿度、开关量等远程监测，但若实施大量的网线铺设是不合理的，而且其监测界面采用C/S模式设计，需要购买昂贵的云台服务器支持数据大规模存储。
发明内容
本发明的目的在于提供一种基于OPPC线的配电网自动化传输系统及方法，以解决变电站数据传输问题。
本发明解决其技术问题所采取的技术方案是：一种基于OPPC线的配电网自动化传输系统及方法，其特征是，它包括连接监控终端和监控接收端的光纤光栅OPPC光缆、与监控接收端连接的路由器、与路由器连接的监控站和服务器站和工作站和网络打印机，监控站、服务器站和工作站与UPS连接。
进一步地，光纤光栅OPPC光缆的两端设计有FAP故障分析保护盘。
进一步地，FAP故障分析保护盘包括单片机、光开关驱动电路、光开关、分光器、光电管、A/D转换器、增益可调放大电路。
本发明的有益效果是：本发明提供的一种基于OPPC线的配电网自动化传输系统及方法，光纤光栅OPPC光缆数据传输稳定可靠，在对传统线路改造的同时无须多架设多余线路，系统在监测终端箱变的内环境信息同时还能对线路本身的状态信息实时监测；B/S架构WEB浏览器上位机可实现灵活监控，兼容性强，操作简便。
附图说明
图1为监控系统整体构成图；
图2为监控系统硬件构成图；
图3为FAP保护盘构成图；
具体实施方式
下面对本发明的传输系统和方法进行详细描述。
如图1所示，分散在城区的各个箱变里均安置有嵌入式监控终端，这些监控终端借助改造过的三相输电线路中的光纤光栅型OPPC线路，把箱变内环境的监测信息远距离传输。监控接收端，把监测数据进行计算处理并通过以太网传递至远方监控室内，工作人员不用安装任何软件，通过任意WEB浏览器即可进行实时监控操作，为了方便工作人员运维和移动式工作，设计有手机APP加载WEB监控界面。监控室内备用电力由UPS供应；服务器站用于解决因数据量增大，嵌入式接收端无法长时间存储数据的问题；网络打印机则在故障事件发生时打印报表或者负责站与站之间的通信工作。
如图2所示，主控盘接收与发送端均选STM32F407高速微控制器为CPU。图中左侧是主控盘发送端，即嵌入式监控终端；右侧是主控盘接收端，即嵌入式服务器；中间虚线框里面的是OPPC光缆传输段。
主控盘发送端使用ATT7022B检测电压、电流、功率等箱变输入输出侧电力信息；采用DHT11小型传感器对箱变局部温湿度信息进行检测；通过调理电路将PT100温度传感器的模拟信号送入STM32的模数转换通道，由转换成的电压值与实际温度进行一一映射；另外当故障发生时，发送端还可以控制箱变执行排风扇进行PID调速、开关智能控制、SIM900A短信报警功能。
OPPC光缆传输段实现监测数据的远距离稳定传输，OPPC两端设计有FAP故障分析保护盘，它不仅能实时检查光缆通讯功率是否达标，也可以实现主、备用路的自主切换，防止主回路损坏造成的长时间通信阻断，把故障损失降到最低；光端机完成光电转换；电源盘则为光缆和光端机提供电源供应。
主控盘接收端不仅可以读取OPPC光缆传输来的监测数据，还可以根据OPPC光缆内的布拉格光栅反射波的波长λ变化量判断传输线路的短路温度或者应力情况，方便导线融冰工作进行；接收端自己成立为独立WEB服务器，通过ENC28J60网线接口与路由相连，网内的计算机或者手机APP均可以对其访问，当故障时不仅可以追踪故障数据所在界面，发送报警短信提示工作人员现场运维，也可以通过阈值或者预警控制算法智能发送开关量信息通过OPPC传输段远距离操控箱变的开关设备。
如图3所示，FAP保护盘是OPPC传输段非常重要的部分，它掌管线路通讯监测、主备用线路切换和STM32主控盘的信息交互等工作。其具体构成如图3所示。C8051控制器借助驱动电路使1×2光开关自主切换主路与备用路。这里以主路说明，光输出的过程是C8051单片机通过光开关将TTL电平信号转换光信号由OPPC输出；光输入过程比较复杂，光经由1×2开关选择进入主路，分光器提取3％的光信号，光电管将其变换为电信号，电信号被放大电路放大之后，进入专门的高精度模数转换器，再交给C8051处理数据，这里的放大电路必须增益可调，以防信号过小监测不到或者信号过大损坏单片机弱电电路。最后，C8051把监测数据与OPPC光缆温度、应力状态信息递交给STM32主控盘处理。
