Description

一种交叉多环网冗余网络拓扑结构的控制系统 技术领域
本申请涉及电力系统通信网络拓扑控制系统领域，尤其涉及一种交叉多环网冗余网络拓扑结构的控制系统。
背景技术
目前，直流换流站阀基控制设备VBC和子模块控制器SMC的通信网络连接，一般采用点对点直接连接方式进行连接并通信，通信网络拓扑结构如图1所示，其中阀基控制设备VBC为控制对象，子模块控制器SMC为被控制对象，控制对象的连接节点与被控制对象的连接节点一一对应，对于N个被控制对象，需要的控制对象连接节点的数量为N组，控制对象的连接节点的数目随着被控制对象的数量增加而增加，从而导致现有技术中，存在通信网络拓扑结构存在控制对象连接接点多，控制对象功耗大的缺点。
发明内容
为了解决现有技术中的缺点，合理减少控制对象连接节点的数量，从而降低控制对象的功耗，本申请提供一种新的具有多环网冗余网络拓扑结构的控制系统。

其中，所述控制对象中任一组第一连接节点与所述多个被控制对象中的至少两个被控制对象的第二连接节点依次连接形成环网，对应所述控制对象的多组第一连接节点形成多个环网，所述多个环网中包含所述多个被控制对象。
根据本申请提供的交叉多环网冗余网络拓扑结构的控制系统，控制 对象的连接节点可以连接多个被控制对象构成环网，能够有效减少控制对象的连接节点的数量，降低了控制对象功耗。而且，由于可以将被控制对象置于多个不同的环网中，所述控制系统中控制对象与被控制对象存在冗余连接，在连接节点、网络出现异常时还有备用冗余网络可以连通，提高了整个控制系统的可靠性。此外，本发明的被控制对象的各组连接节点具备旁路功能，被控制对象故障或者失电时实现节点直通，不影响控制对象和其它被控制对象的通信。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请中，通过将多个被控制对象与控制对象的一组连接节点相 连构成环网，能够大大减少所需的控制对象的连接节点的数量，从而减少控制对象的功耗。由于可以将被控制对象只与多个不同的环网中，所述控制系统中控制对象与被控制对象存在冗余连接，在连接节点、网络出现异常时还有备用冗余网络可以连通，提高了整个控制系统的可靠性。
图2为根据本发明一个实施例的交叉多环网冗余网络拓扑结构的控制系统的示意图。如图2所示，控制系统包括一个控制对象和五个被控制对象，其中，控制对象包括直流换流站阀基控制设备、变电站电厂远动装置、监控后台、保护信息子站等，被控制对象包括子模块控制器、变电站电厂保护装置、测控装置、智能终端等。控制对象具有三组连接节点(1-1，1-2)、(2-1，2-2)和(3-1，3-2)，而被控制对象分别具有两组连接节点(1-1，1-2)和(2-1，2-2)，在本申请的附图中的“接点”表示“连接节点”的意思。
为了方便描述，将控制对象和被控制对象的连接节点分别成为第一连接节点和第二连接节点。一组第一连接节点和一组第二连接节点均包括连通的输出连接节点和输入连接节点，即一组连接节点一个作为输出连接节点，另一个就作为输入连接节点。例如，连接节点(1-1，1-2)，1-2作为输出连接节点，1-1就作为输入连接节点。
在图2所示的实施例中，控制对象的输出连接节点1-2、被控制对象1.1的1-1、被控制对象1.1的1-2、被控制对象1.2的1-1、被控制对象1.2的1-2、被控制对象2.1的2-1、被控制对象2.1的2-2、控制对象的输入连接节点1-1依次连接组成一个环网，该环网中共有3个被控制对象。
在图2所示的实施例中，控制对象的输出连接节点2-2、被控制对象1.2的2-1、被控制对象2.1的2-2、被控制对象1.3的2-1、被控制对象1.3的2-2、被控制对象2.2的1-1、被控制对象2.2的1-2、控制对象的输入连接节点2-1依次连接组成一个环网，该环网中共有3个被控制对象。
在图2所示的实施例中，控制对象的输出连接节点3-2、被控制对象1.3的1-1、被控制对象1.3的1-2、被控制对象2.2的2-1、被控制对 象2.2的2-2、被控制对象1.1的2-1、被控制对象1.1的2-2、控制对象的输入连接节点3-1依次连接组成一个环网，该环网中共有3个被控制对象。
在图2所示的实施例中，同一控制对象的不同组的第一连接节点位于不同的环网，例如，控制对象的连接节点(1-1，1-2)和(2-1，2-2)位于不同的环网。在图2所示的实施例中，同一被控制对象的不同组的第二连接节点位于不同的环网，例如，被控制对象1.1的连接节点(1-1，1-2)和(2-1，2-2)位于不同的环网。
在图2所示的实施例中，共有五个被控制对象，控制对象与被控制对象的连接节点的环网覆盖这五个被控制对象，且控制对象的连接节点的数量只需三组，可见能够减少控制对象的连接节点的数量。图2中只有五个被控制对象，这只是为了便于说明本发明的方案而给出的一个简单的实施例，现实应用中，随着被控制对象数量的增加，控制对象连接节点的数量相对于现有技术的方案，减少的更加可观。
另外，在图2中存在三个环网，被控制对象1.1、1.2、1.3和2.2的两组连接节点位于不同的环网中，例如，被控制对象1.1的连接节点(1-1，1-2)和(2-1，2-2)分别位于实线和虚线环网中，即被控制对象1.1、1.2、1.3和2.2存在于两个环网中。这样，当连接节点、网络出现异常时还有备用冗余网络可以连通，例如，对于被控制对象1.1来说，当图2中实线所示的环网出现异常时，可以通过虚线所示的环网与控制对象进行通信，从而提高了整个控制系统的可靠性。
图3为根据本发明另一个实施例的交叉多环网冗余网络拓扑结构的控制系统的示意图。与图2相比，不同之处在于：对于图2中，控制对象的输出连接节点3-2、被控制对象1.3的1-1、被控制对象1.3的1-2、被控制对象2.2的2-1、被控制对象2.2的2-2、被控制对象1.1的2-1、被控制对象1.1的2-2、控制对象的输入连接节点3-1依次连接组成一个环网，在图3中，该环网还包括被控制对象2.1的1-1和被控制对象2.1的1-2，共有4个被控制对象。
这样，在图2所示的实施例中，被控制对象2.1只存在于一个环网中，当这个环网出现异常时，被控制对象2.1没有备用冗余网络可以连 通。而在图3所示的实施例中，被控制对象2.1存在于两个环网中，当一个环网出现异常时，被控制对象2.1还有备用冗余网络可以连通。
在图2和图3所示的实施例中，当一个被控制对象故障或者失电时，该被控制对象将各组连接节点设置为导通状态。例如，当被控制对象1.1故障或者失电时，被控制对象1.1将自己的连接节点(1-1，1-2)和(2-1，2-2)处于导通状态，不影响环网中其他被控制对象与控制对象的通信。
在图2和图3所示的实施例中，被控制对象有两组连接接口，然而被控制对象的连接接口可以为任意组，即可以为一组，也可以多于两组。当被控制对象具有多组连接节点的情况下，多个环网连接多组连接节点中的一组，也可连接多组连接节点中的至少两组。
需要注意的是，图2和图3只是为了便于说明本申请方式的两个具体实现方式，本领域技术人员在此启发下可以获得各种不同实现方式，例如，被控制对象的数量可以是任意多个，被控制对象的连接节点可以是任意组，控制对象的连接节点也可以是任意组，这些都属于本申请覆盖的范围。
根据本申请的上述技术原理，下面结合图4、图5、图6和图7给出一些优选实现方式。需要注意的是，图4、图5、图6和图7的实施例只是为了进一步阐述本申请方案的具体实施例，并不能理解为对本申请保护范围的限制。
