Description

Module of load distribution and automatic frequency regulation of electric generator (MLI A108I) is designed to ensure the possibility of operation of one power unit or synchronously several power units in the mode of automatic power regulation with frequency correction or in the mode of astatic frequency regulation with fulfilment of System Operator's requirements.
The basis for the implementation of MLI A108I is the INCONT PTC, the module is built on the basis of technical means and software of the INCONT PTC.
The module is created in full compliance with the Customer's Technical Requirements RGT.6F.03.A108I.001TT and technical specifications for the INCONT PTC TU 26.51.70-007-20018692-2019.
The MLI A108I module of load distribution and automatic frequency control of the electric generator is created in the form of a single-sided service cabinet installed inside the station room.
