Description

基于CAN总线的对并联电源在线均流控制的监控系统
技术领域
本实用新型涉及一种变电站用监测设备,尤其涉及这一种均流控制的监控系统的改进。
背景技术
传统的变电站内部的二次侧电源设备都采用电池组串联的接线方式，其特点在于将电池组串联，直接提升整套电池组的端电压，并接入直流系统作为备用电源使用。目前的变电站站用电屏，采用串联电源的接线方式，其均流手段主要通过模块自身进行均流，监控系统仅担任信息采集的作用，如果模块均流过程中发生类似交流失电等情况，则会对供电设备产生极大影响。
实用新型内容
为了克服现有技术的不足，本实用新型提供了一种在交流失电状态下不影响供电的基于CAN总线的对并联电源在线均流控制的监控系统。
本实用新型采用如下技术方案实现：基于CAN总线的对并联电源在线均流控制的监控系统，包括监控部、通信部、监测部，所述监测部设于电源模块上且通过所述通信部信号连接所述监控部；
所述监控部包括传感器模组、供电模组和信号传输模组，所述供电模组分别给所述传感器模组和所述信号传输模组供电，所述传感器模组设于所述电源模块上且与所述监控部信号连接，所述信号传输模组将所述传感器模组接收到的信号通过CAN总线传输到通信部，所述供电模组包括主供电电源和副供电电源，主供电电源和副供电电源之间设有用于转换所述主供电电源和副供电电源的投切装置。
所述主供电电源为电源模块，所述电源模块上设有供电回路，所述供电回路分别给所述传感器模组和所述信号传输模组供电。
所述副供电电源为备用电池，所述备用电池通过电源模块充电，所述备用电池给所述传感器模组和所述信号传输模组供电，所述投切装置设于所述主供电电源和副供电电源之间。
所述投切装置包括从所述主供电电源的输出口取电的控制线圈和与所述控制线圈联动的常闭触点，所述常闭触点设于所述副供电电源的输出口。
相比现有技术，本实用新型通过CAN总线通信、下属并联电源模块拨码地址进行对所有模块的侦听。在站用屏系统稳态运行时，多个模块电源并联的系统在稳定的工作状态下输出稳定的直流电压，而单个模块电源输出电流的大小是由这个模块电源的输出阻抗和控制输出电压的大小决定的，因此，可以将一个模块电源等效看作直流电压源和输出阻抗串联的形式。在CAN总线侦听到模块电流出现问题后，会下发均流指令并全程跟踪模块均流信息，记录故障时间点与故障、均流信息，加以记录，并从后台机通过外部通信将此次监控参与的均流事件上送至调度和用户侧云服务器。由于是并联电源系统，即使在均流过程中发生交流失电等意外情况也不影响站用电设备的正常工作。
附图说明
图1是本实用新型结构示意框图；
具体实施方式
下面，结合附图以及具体实施方式，对本实用新型做进一步描述，需要说明的是，在不相冲突的前提下，以下描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例。

上述实施方式仅为本实用新型的优选实施方式，不能以此来限定本实用新型保护的范围，本领域的技术人员在本实用新型的基础上所做的任何非实质性的变化及替换均属于本实用新型所要求保护的范围。
