With the development of digitization of substation, the future trend of on-line monitoring system of substation power equipment is adopting the IEC61850 standard to realize seamless communication. However, the change of distance and node make synchronization precission of samples transmission become a problem. An implementation method based on the IEEE1588 standard is proposed, by use of DP83640 Ethernet...
In China, there is now a growing desire to use the IEC60870-5 standards to communicate between telecontrol stations via Internet services in power telecontrol systems. A companion standard called IEC 60870-5-104 has been published by the IEC for this purpose. At present, people make a deep study of the application of the 104 protocol and have obtained a certain success. But on the software design,...
In China power systems began to carry out the international standard protocol-IEC60870-5-101 as the communication protocol for telecontrol, teleprotection, and associated telecommunications in 1998. For the sake of the generalization of IEC60870-5-101 standard and the development of the high quality software, this paper introduces the finite state machine (FSM) theory for design of the communication...
