Patent number: 9537648Abstract: A method for transmitting measurement data includes receiving measurement data in a first communication module, time stamping the measurement data in the first module with a time tag, transmitting the measurement data to a second communication module via a packet switched data network, and outputting the transmitted measurement data after a predefined delay time ?tD after the time stamping of the measurement data.Type: GrantFiled: July 18, 2014Date of Patent: January 3, 2017Assignee: ABB Schweiz AGInventors: Dominique Cachin, Ramon Bächli, Alex Gygax, Hermann Spiess

Patent number: 9001675Abstract: Exemplary embodiments increase reliability of communication over a non-deterministic communication channel, in electric power systems. A communication channel is monitored based on regular network traffic, by evaluating messages or data packets carrying real-time operational data as a payload. A permanent 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 can include identical payloads reflecting current states rather than state changes as operational data.Type: GrantFiled: July 13, 2011Date of Patent: April 7, 2015Assignee: ABB Technology AGInventors: Wolfgang Wimmer, Hubert Kirrmann, Hermann Spiess, Stefan Ramseier, Allen Notter, Martin Israel

Patent number: 7952846Abstract: 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 in a frequency band and a guard signal located in a first half of the frequency band. For successive lines, a repeating sequence of different schemes of command signals is used, each of the schemes comprising only command signals with frequencies located in a second half of the frequency band. By using a repeating sequence of different schemes for successive lines and by using in each of the schemes only command signals 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 used for coding (tele-) protection commands.Type: GrantFiled: April 5, 2007Date of Patent: May 31, 2011Assignee: ABB Technology AGInventor: Hermann Spiess

Patent number: 7372808Abstract: In a method and a device for redundant transmission of protection commands between remote tripping devices (1, 8), useful information which represents a protection command or a rest signal is transmitted by a first remote tripping device (1) in at least two time slots via a first interface (2) to a first multiplexer (3), and is transmitted via different transmission paths (4, 5) by the multiplexer (3) based on the time slots. A second multiplexer (6) receives the useful information via the different transmission paths (4, 5), and transmits each useful information item via a time slot, which is allocated to the respective transmission path (4, 5), in a second interface (7) to a second remote tripping device (8).Type: GrantFiled: March 26, 2003Date of Patent: May 13, 2008Assignee: ABB Schweiz AGInventors: Hermann Spiess, Michael Strittmatter, Mathias Kranich

Patent number: 7173800Abstract: In a method and a detector (7) for time-optimum reception of protection commands in a remote tripping device, at least two detector elements (1, 2) are operated, which are all designed for a signal at the same frequency but for different transmission times. Where at least one of these detector elements (1, 2) detects the presence of the signal, the signal is regarded as having been detected.Type: GrantFiled: February 5, 2003Date of Patent: February 6, 2007Assignee: ABB Schweiz AGInventors: Hermann Spiess, Hans Benninger
