Description
S9 in medium- and high-voltage design (S9M1D – MV, S9H1D – HV) is the largest frame size of the S-Range family for generator sets operating on medium-voltage networks. Medium- and high-voltage machines cover the range 2150–4500 kVA at 50 Hz and 2400–5600 kVA at 60 Hz (depending on the voltage); the overall voltage range of the series is 380–13,800 V. According to the technical data sheets, medium-voltage versions are rated for 4.16 kV, and high-voltage versions in particular for 12.47, 13.2 and 13.8 kV. The generator is four-pole, brushless, with a rotating field and excitation from a permanent-magnet pilot exciter (PMG). Voltage regulators: DM110, DECS100 or DECS150, voltage regulation accuracy ±0.25 % with 4 % droop of the engine governor. The stator winding is double-layer lap; for medium- and high-voltage versions pitches of 2/3 and 5/6 are used. Insulation class H, degree of protection IP23. CoreCooling technology increases specific output and improves the thermal regime. According to the data sheets the efficiency of the 4.16 kV medium-voltage machine reaches about 97 %; the distortion of the voltage waveform at no load is less than 1.5 %, at linear load less than 5 %, and the telephone interference factor TIF is below 50. The data sheets give a full set of reactances and time constants for calculating short-circuit currents and stability. Options: bearing temperature sensors, air cover and inlet filter, diode failure detector, loss-of-excitation module, quadrature droop kit, anti-condensation heaters. Radio interference suppression according to BS EN 61000-6-2 and 61000-6-4, VDE 0875G/N. The generators meet the requirements of IEC 60034 and sections BS5000-3, ISO 8528-3, VDE 0530, NEMA MG1-32, CSA C22.2-100 and AS 60034, and are manufactured under a quality system to BS EN ISO 9001. Applications: gas-engine and diesel power stations feeding into the medium-voltage network, data centres with distribution at 4.16–13.8 kV, cogeneration, industrial and oil and gas power stations, primary and standby supply. Connecting the generator directly to 6–13.8 kV busbars makes it possible to dispense with step-up transformers and reduce losses.
