Research on Network Transmission Mode of Remote Data Based on IEC-101 of Dispatching Data Network

传统模式下的IEC-101远动数据传输方式已不符合安全防护的要求,IEC-104网络通信由于传输速度快、通道误码低、数据安全加密、故障定位方便等优点已成为主流远动通信方式,为了综合利用IEC-104及IEC-101的优点,提出了一种基于IEC-101远动数据网络化传输方式。该方式既可满足安全防护的要求,又可结合双规约的共同优点进行远动数据的可靠传输,同时也可实现备调系统"IEC-101+IEC-104"方式的双通道接入,满足备调系统实时数据冗余性需求。

The traditional mode of IEC-101 remote data transmission method does not meet the requirements of safety protection. IEC-104 network communication,due to its fast transmission speed,low channel error,data encryption,fault location convenience,has become the mainstream of remote data communication. In order to comprehensively utilize the advantages of IEC-104 and IEC-101,this paper proposes a research on the transmission mode based on IEC-101 remote data network. The method can not only meet the requirements of safety protection but also transmit the reliable data of the remote data in combination with the common advantages of the double protocol,and simultaneously realize the dual access of the ＂ IEC-101 ＋ IEC-104＂,and satisfy backup system real-time data redundancy requirements.
