Brief Description of Main Solutions
With the aim to increase the load capacity of the Unit No. 5 of Burshtyn TPP, in connection with the turbine and boiler reconstruction, provided for is the reconstruction of the stator and rotor of the reserve turbine generator ТГВ-200М. The reconstructed turbine generator is to be installed instead of the existing turbine generator ТГВ-200.
With the aim to ensure the turbine generator reliable operation provided for is reconstruction of the stator cooling system (with the strainer filters, magnet filters and ion-exchange filters to be installed), the gas system and replacement of the existing thyristor excitation system with the excitation transformer by the up-to-date system of the UNITROL 6800 type of «АВВ» company.
