智能电容器组用智能监控器
技术领域
本发明属于设备监控技术领域，特别涉及一种智能电容器组用智能监控器。
背景技术
在工业和生活用电负载中，阻感负载占有很大的比例，这些阻感负载是产生无功功率的主要因素。在某些情况下，无功功率对配电网产生一定的不良影响。利用补偿设备进行无功补偿是解决无功影响的重要手段，智能电容器是常用的无功补偿设备。
智能电容器包含电容器和智能控制器，智能控制器控制电容器过零投切，对低压线路进行无功功率补偿。智能电容器具有智能化、小型化、网络化等特点。多台智能电容器并联使用可提高无功补偿的容量，同时也可以灵活调节无功功率的大小。多台智能电容器构成了智能电容器组，其中一台作为主机，其他智能电容器作为从机，实现无功补偿功能。在现有产品中，单台智能电容器监控自身的状态，没有监控整个智能电容器组的功能，影响了智能电容器组使用的方便性。
发明内容
本发明的目的在于，提出一种智能电容器组用智能监控器，用于进行智能电容器组运行状态的监控。
为了实现上述目的，本发明提出的技术方案是通过触摸屏构成人机交互平台，对触摸屏进行操作，通过通讯线对各台智能电容器进行监控。其特征在于，主要由触摸屏人机界面构成，包含触摸屏、CPU、存储器、串行通讯端口，完成对智能电容器组的监控功能；智能监控器与各台智能电容器之间通过RS485通讯线相连，对每一台智能电容器发送状态查询指令，智能电容器收到命令后将状态信息反馈给智能监控器，并在触摸屏上显示；通过对触摸屏的操作生成投切指令并发送给相对应的智能电容器，进行智能电容器的投切控制。
所述触摸屏包含PLC，PLC采用ABCompactLogix/ControlLogix系列。
所述通过RS485发送智能电容器投切指令，智能电容器接收到指令后进行投入和切除的操作。
所述智能电容器的台数小于32台，每一台智能电容器设置独立的地址。
本发明的优点在于：可通过智能监控器对智能电容器组的每一台智能电容器进行参数和状态显示，方便且直观；通过智能监控器可以操作任意一台智能电容器的投切，简单方便地控制智能电容器组；智能监控器作为独立设备易于安装。具有很高的推广价值。
附图说明
图1为本发明的智能电容器组用智能监控器结构示意图；
图2为本发明的智能电容器组用智能监控器功能示意图。
具体实施方式
本发明提供了一种智能电容器组用智能监控器，下面通过附图说明和具体实施方式对本发明做进一步说明。
图1为本发明的智能电容器组用智能监控器结构示意图，多台智能电容器并联运行，其中一台作为主机，其余作为从机，设置主机和从机的通讯地址。主机将根据功率因数和无功功率生成投切指令，主机的投切由主机的投切指令控制，主机通过RS485通讯发送从机投切指令进行从机的投切控制，从机接收到投切指令后投切电容器。智能电容器组中增加智能监控器，通过RS485通讯线与各智能电容器相连。当智能监控器进行监控时需先与主机进行通讯，通知主机智能监控器要进行的命令，防止主机和智能监控器同时向从机发送RS485通讯信息，保证RS485通讯的发送和接收的时序，以免出现RS485通讯故障。智能监控器应用RS485通讯通过每一台智能电容器独立的地址寻找到该智能电容器，智能电容器将接收到的通讯地址与自己地址进行比较，如果地址相同该从机被唤醒，并进行指令操作，如果从机接收到的通讯地址与自己地址不同，该从机进入静默状态。在触摸屏上触摸相应的选项可以对该智能电容器进行操作，智能电容器通过RS485通讯将参数和状态信息返回给智能监控器。
图2为本发明的智能电容器组用智能监控器功能示意图。智能监控器在触摸屏上显示各智能电容器的参数和状态信息，包含从机数、通讯故障指示、运行总故障指示、对智能电容器全部投入控制、对智能电容器全部切除控制、分补或共补的显示、温度、三相电压和功率因数、每一台智能电容器的投切状态等；智能监控器可对任意一台智能电容器进行投切操作。通过对智能监控器进行编程实现监控功能，并转化为RS485通讯信息与各台智能电容器进行信息传递。
通过上述说明可方便和直观地显示各台智能电容器的状态，简单方便地控制智能电容器组。
