Technical re-equipment of the st. #. 1 excitation system G-1 TVV-320 (thermal power plant (TPP)

Equipment used, specifics of works provided

1. Designing the replacement of the 320 MW TG excitation system with a static thyristor self-excitation system SVTG-3.2k/500-1 KS2T2.5-AR24-UHL4 (SPE “PREOBRAZOVATEL-KOMPLEX” LLC) with nonlinear damping resistors Metrosil FME/8000/600A/US12P/4PP/2SS, which works in conjunction with the Emerson Ovation ATS.
2. Replacement of the unit’s RPA with ATS terminals (RET670, REG670 and others), replacement of the generator circuit breaker with a 20kV, 13.3 kA FKG1F (ALSTOM) circuit breaker with a 120 kA breaking capacity, replacement of the synchronizer with a SYNCHROTACT 6 SYN6201 ATS, complex automation, inspection of building structures, architectural and construction part (strengthening of supporting structures for installation of power transformer TSZP-4130/20-U3 (PE “ELTIZ”) weighing 11.6 tons. ), heating and ventilation (use of precision air conditioners to cool down the transformer room).
3. Within the framework of the project, dynamic stability calculations were implemented in accordance with the requirements of SOU-N IEC 40.1-00100227-68 2012 “Power System Sustainability. Guidelines” (models of the ST4C thyristor self-excitation regulator and the PSS2B system stabilizer in accordance with the requirements of IEEE 421.5 Recommended Practice for Excitation System Models for Power System Stability Studies)
