METHOD FOR TRANSMITTING MEASUREMENTS IN A PROCESS DATA TRANSMISSION NETWORK Russian patent published in 2020 - IPC H02H3/00 G01R19/165 G06F3/05 

FIELD: electric power engineering.

SUBSTANCE: invention can be used in power engineering and is intended for use in power supply to consumers using intelligent networks with electric power sources. According to the method, the instantaneous voltage and / or current value of the power facility is measured in the measuring part of the RPA complex, which is conjugated with the power facility, determination of the vector of their operating values over the period of the industrial frequency and transmitting, at a predetermined periodicity, GOOSE messages on current and / or voltage actual values to the remote protection logic node through the local area network, detecting increment of emergency currents and transmitting GOOSE messages with vector signals, wherein increment is determined from ratio where is current complex current value of sequence Φ (direct, inverse or zero), is complex current value of sequence Φ (forward, inverse or zero) 20 ms back, generation of GOOSE-messages corresponding to the technological failure mode is performed, as long as the firing element in the device for interfacing with the power object records currents of the forward, reverse or zero sequence above the threshold value. Additionally vector values of current and / or voltage are presented in the form of amplitude and angle or real and imaginary part. In normal mode of power facility GOOSE-messages on vectors of current values of current and / or voltage are transmitted with periodicity every 2 seconds. At onset of process violation at power facility, time delay is set before sending GOOSE-messages on vectors of active values of voltage or current equal to 10 ms, periodicity of GOOSE-messages is 10 ms, and repetitive transmissions with an invariable data set within each GOOSE message are performed through increasing time intervals of 1 ms, 2 ms, 4 ms.

EFFECT: reduced load on communication data bus and reduced number of equipment used for construction of communication network.
