At the commission of "Zakhidenergo" OJSC, SOYUZ Corporation has committed to perform work on reconstruction of turbogenerator and its thyristor excitation system at power unit No. 5 of DTEK Burshtyn CHP.
During the reconstruction of the turbogenerator at the power unit No. 5 the following works were performed at specified contract terms:
Reconstruction of turbogenerator TGV-200
To ensure increase of the turbogenerator the following actions were performed:
-
complete replacement of the stator windings and recovery of active iron characteristics at the site of Burshtyn CHP;
-
reconstruction of the rotor at the production site of manufacturing plant;
-
drafted the replacement of hydrogen cooling of the stator winding by water cooling, as well as replacement of generator excitation system.
Excitation system UNITROL 6800
-
сompleted installation of excitation system;
-
сompleted reconstruction of backup exciter choice control with replacement of DC disconnectors and protective cabinet;
-
сompleted installation of excitation transformer protection system and interface connection with the main control unit;
Specific feature of the excitation system reconstruction was providing possibility, at the commission of the station, of the system operation in asynchronous mode.
