摘要： A method for transmitting measurement data 28a comprise the steps of: receiving measurement data 28a in a first communication module 22a; time stamping the measurement data 28a in the first module with a time tag 34; transmitting the measurement data 28a to a second communication module 22b via a packet switched data network 24; and outputting the transmitted measurement data 30a after a predefined delay time Δt D after the time stamping of the measurement data 28a.

摘要： The present invention increases reliability of communication over a non-deterministic communication channel, and is particularly suited for inter-substation teleprotection in electric power systems. A communication channel is being monitored based on regular network traffic, i.e. by evaluating messages or data packets carrying real-time operational data as a payload. A continuous determination of a channel quality, including appropriate alarming in case the channel quality is found insufficient, is based on an evaluation, at a receiving node, of data packets continually transmitted by a sending node. These continually or repeatedly transmitted data packets may comprise identical payloads reflecting current states rather than state changes as operational data.

摘要： In an electric power transmission network, comprising several substations interconnected by power transmission lines, a communication device of a substation communicates over a power transmission line to a communication device of a neighboring substation by using command signals (A, B, C, D) in a frequency band (F) and a guard signal (G) located in a first half (F2) of the frequency band (F). For successive lines, a repeating sequence of different schemes (a1, b1) of command signals (A, B, C, D) is used, each of the schemes (a1, b1) comprising only command signals (A, B, C, D) with frequencies located in a second half of the frequency band (F1). By using a repeating sequence of different schemes (a1, b1) for successive lines and by using in each of the schemes (a1, b1) only command signals (A, B, C, D) with frequencies located in one half of the reserved frequency band, it is possible to reduce the number of different frequency bands required in electric power transmission networks for transmitting command signals (A, B, C, D) used for coding (tele-) protection commands.
