摘要
电子式互感器数字接口使用常规以太网组播/广播模式进行通信,存在载波冲突、网络负载过重和广播风暴等问题。在分析了电子式互感器数字通信和VLAN技术特点的基础上,对变电站网络建设和电子式互感器数字传输帧做了一定的改进,并设计了一套基于VLAN技术的电子式互感器数字接口,使其利于互感器与二次设备利用组播/广播模式进行实时数据传输,从而提高了电子式互感器和二次设备之间通信的实时性和可靠性。
The multicast/broadcast model is adopted in the communication for the digital interface of electronic transducer based on general Ethernet. There are some disadvantages of carrier collision, network overload, broadcast storm etc. From the analysis of the communication of electronic transducer and the VLAN technology, the presented work improved on the network building of the substations and the communication frame of the electronic transducers and designed a set of digital interface of electronic transducer based on VLAN technology. The real-time feature and reliability of the communication between the electronic transducers and the secondary devices is improved.
