摘要

Elaboration of IEC 61850 process bus for the generator-transformer unit of Nizhegorodskaya HPP began in 2015, when the Unit #6 of Nizhegorodskaya HPP was selected as a pilot facility for testing the technology of the process bus in accordance with the requirements of IEC 61850 standard. The electronic fiber-optical current transformers and the electronic voltage transformers with capacitive divider were installed in the circuits of the 110-kV switch of the T-6 power transformer; the flexible electronic fiber-optical current transformers were installed in the main leads and in the neutral of the generator #6; the merging unit as the digital measuring voltage transducer in the main leads and in the neutral of the generator connected to the star scheme of the conventional voltage transformer of the main leads and to the branch line of the arc-suppression reactor of the generator's neutral was in-stalled. In 2017, the range of the electronic instrument transformers was expanded by the single-phase voltage and direct current transformers in the excitation system, the three-phase alternating current (AC) voltage transformer with the resistive divider in the leads of the generator and the single-phase AC voltage transformer in the generator's neutral. The output signals for all current and voltage transformers which are installed are following - digital flow IEC 61850-9-2LE SV80/SV256 [1].
