Description

一种10kV或20kV线路为供电区域的电压无功优化补偿方法
所属技术领域
本发明涉及一种10kV或20kV线路为供电区域的电压无功优化补偿方法，属输配电技术领域。
背景技术
目前，我国10kV或20kV线路及供电区域的无功补偿多采用分散的无功补偿装置，实现局部点的无功补偿，各个无功补偿装置相互之间没有任何联系，而且无功补偿装置的运行只受控于自身的就地采集量，通常不具备网络及远程控制功能，不能达到最优的补偿效果，会因缺乏协调而引起各就地补偿装置的频繁动作以及补偿精度的降低。
发明目的与内容
一条10kV或20kV线路连接有若干台配电变压器，分布到各个用电地点，配电变压器将高压10kV或20kV变成低压400V供给各种用电器用电，形成一个10kV或20kV线路供电区域(简称：线域)。
本发明提供一种10kV或20kV线路为供电区域的电压无功优化补偿方法，以有线或无线网络作为数据的传输平台，通过对10kV或20kV线域参数进行实时监测和分析，实现线域无功补偿的优化控制和优化调度，充分发挥各终端补偿设备的潜力，保障该线域的无功优化平衡，以达到整个线域系统运行在最佳工况及最小线损的目的。
为达到上述目的，本发明采取的技术路线如下：
每台配电变压器或选择部分配电变压器400V侧安装具有通信功能的无功自动补偿装置(简称：400V终端补偿装置)，同时可在10kV或20kV线路上择点安装一台或若干台10kV或20kV线路终端补偿装置，安装终端补偿装置的接入点称作补偿节点，各终端补偿装置和线域电压无功优化补偿控制中心(简称：线域控制中心)之间，可以通过有线或无线通信方式进行通信，各个终端补偿装置可以接受线域控制中心的指令并动作，线域控制中心可以接收各个终端补偿装置的电气参数信息进行分析计算，并且能够根据计算结果发出指令，形成一个10kV或20kV线路为供电区域的电压无功优化补偿系统(简称：线域电压无功优化补偿系统)。
通常情况下各终端补偿装置自动跟踪负荷变化，独立工作自动补偿，使补偿节点无功平衡电压最优，同时将电气参数信息传送到线域补偿控制中心。当某个或几个终端补偿装置不能满足对应的补偿节点的无功平衡要求时，线域控制中心运用多机协同处理算法，寻求最优补偿节点和补偿容量，将优化补偿控制指令发送给其它相应的补偿节点的终端补偿装置，终端补偿装置响应并动作，使上述补偿节点达到无功平衡电压最优，以保证线域处处无功平衡、电压最优。
