一种基于自组网调度的电能质量治理设备多机并联方法
技术领域
本发明涉及低压配电网技术，尤其涉及一种基于自组网调度的电能质量治理设备多机并联方法。

发明内容
本发明针对现有技术存在的不足和缺陷，提供了一种基于自组网调度的电能质量治理设备多机并联方法，通过CAN总线连接多个电能质量治理设备进行通信，具有数据通信实时性强、灵活性强、可靠性高的特点，将组网调度功能集成于电能质量治理设备内，主机实时查询、调度各个从机，动态调整组网设备的补偿系数，提高电能质量治理设备的补偿效果。
为了实现上述发明目的，本发明提供了一种基于自组网调度的电能质量治理设备多机并联方法，包括以下步骤：
步骤1：电能质量治理设备故障自诊断；
步骤2：电能质量治理设备主机查询各个电能质量治理设备从机的工作模式、运行状态、容量参数，完成从机参数统计；
步骤3：判断电能质量治理设备从机工作模式；
步骤4：若存在以下任意一种情况，将电能质量治理设备从机容量加入至并机总量中：
1)电能质量治理设备从机工作模式与主机工作模式相同；
2)无故障运行或新增无故障运行
3)与电能质量治理设备主机工作模式相同的电能质量治理设备从机设备或电能质量治理设备从机工作状态由待机或故障转为运行状态；
若存在以下任意一种情况，将电能质量治理设备从机容量加入至并机总量中：
1)若已并联电能质量治理设备从机工作模式与电能质量治理设备主机工作模式不一致；
2)电能质量治理设备从机工作状态由运行状态转为待机或故障状态；
3)电能质量治理设备主机无法与电能质量治理设备从机正常通信；
主机完成并机总量统计；
步骤5：电能质量治理设备主机广播并机总容量，从机接收并机总量，单台设备容量除以并机总容量为设备补偿系数，单台设备实际出力为负载电流与设备补偿系数的乘积，完成多机并联。
进一步的，电能质量治理设备从机在规定时间内未收到电能质量治理设备主机信息，则认为电能质量治理设备主机故障，编号最小的电能质量治理设备从机成为新主机，新主机按照上述原则统计并机容量，协调各个电能质量治理设备从机工作，原主机恢复正常上线后，新主机将主机权交还原主机。
本发明的有益效果是：CAN总线连接多个电能质量治理设备，各个设备具有故障自诊断功能，无故障且工作模式相同的设备自动组网，协调工作，可靠性、灵活性更高，具有更强的工程实用性。
