Synchronization of data acquisition devices of an online monitoring system for monitoring an electrical distribution network through detection of zero crossings
An arrangement for synchronization between at least two data acquisition devices of an online monitoring system for monitoring an electrical distribution network, each located at a known point A or B in the network and configured to detect high-frequency events during data acquisition phases. During a first phase of estimating the period of the electrical signal travelling through the network, each data acquisition device samples the electrical signal travelling through the network and deduces therefrom an estimate T′A or T′B of the period of the electrical signal by detecting times of zero crossings of the sampled signal, which are locally timestamped by a timestamping means associated with each data acquisition device. One of the devices then sends an information signal at a first time of detection tZCA1,1, which is locally timestamped, of a new zero crossing of the sampled signal, and triggers a data acquisition phase at a first time TRA separated from the first time of detection by a duration corresponding to the first estimate T′A of the period of the electrical signal. The time of reception of this signal at the other device is also timestamped by a local timestamping means. After a duration corresponding to half the second estimate T′B of the period of the electrical signal following the time of reception has elapsed, this other device triggers a phase of acquiring high-frequency events over a plurality of successive cycles having a predefined cycle duration, at a second triggering time tRB determined locally and corresponding to a second time of detection of a new zero crossing of the locally sampled signal. It is then possible to determine a synchronization difference Δtoa between two high-frequency events acquired, over a given cycle, by the two data acquisition devices by calculating the difference between the second triggering time tRB and the first triggering time tRA.
