Static Frequency Converter (SFC) TMP-TS370 Series

1 TMP-TS370 SeriesStatic Frequency ConverterFeatures (1) is a load commutated inverter (LCI), which drives a gas turbine generator like a synchronous motor, and accelerates up to the gas turbine s self-sustaining speed. Our new compact SFC, TMP-TS370 Series , accumulates all major components in a single compact package. This contributes easy site work and space-saving for ReliabilityTMEIC has over 3 decades experience and more than 170 SFC units with a total capacity more than 900MW in all over the world. We are continually developing SFC based on well-proven technology. This increases the reliability, safety and for Hydro power plantThe 1stGenerationUse for Thermal power plant(CE-HV Type)The 2ndGeneration(CK-HV Type)The 3rdGeneration(CF-WA Type)The 4thGeneration(TMP-TS150/TS170/TS270 Type)The 5thGeneration(TMP-TS250/TS250T Type)To t a l ;More than 170 units, 6th Generation( TMP-TS370 /TS370T Type)Old type SFCNew type InstallTMP-TS370 accommodates all circuits, including power converters, dc reactor and controls, in one package.
