Description
LSMV-M1000 is a series of medium-voltage variable frequency drives for speed control of induction motors of 3–11 kV in pumping, fan, compressor and other drives. The model code is formed as LSMVM1000-[input voltage][output voltage][frequency][power]. Topology: a cascaded multilevel H-bridge inverter, in which low-voltage single-phase power cells are connected in series in each phase, forming a multilevel PWM voltage with up to 37 levels and a near-sinusoidal output current waveform. The cells are supplied from a multi-winding phase-shifting input transformer ('extended delta' connection) with separate multipulse rectifiers; the transformer has class H insulation with air cooling, and oil-filled is optional. Thanks to the multipulse input, the harmonic content of the input current complies with IEEE 519-1992, and no input or output filters are required. Characteristics: voltage classes 3, 4, 6, 10 and 11 kV (input and output voltages 3.0; 3.3; 4.16; 6.0; 6.6; 10.0 and 11.0 kV); power 200–12,500 kVA, maximum motor power from 160 kW (200 kVA, 3 kV class) to 10,000 kW (12,500 kVA, 6.6 kV class); input voltage tolerance ±10 %, 50/60 Hz; efficiency about 97 % at rated speed and load; power factor not less than 0.95 without an external compensator; output frequency 0–120 Hz. Air cooling, with fan speed control by internal temperature and optional fan redundancy. Control: V/f and sensorless vector control with auto-tuning, pickup of a rotating motor, bypass of a faulty cell, and continued operation during voltage dips of up to 5 cycles; built-in PLC, 10.2-inch HMI, RS-485 as standard, and optionally DeviceNet, Profibus, Modbus-RTU and Metasys N2. Protections: overcurrent, overload, input and output phase loss, cell overheating. Protection degree IP31 (IP42 optional); conditions: 0–40 °C, humidity up to 85 %, altitude up to 1000 m. CE certificate. Applications: oil and gas industry, water treatment and wastewater, power plants (pumps, fans, induced-draft fans), metallurgy, chemicals, cement, pulp and paper industry; conveyors, mills and crushers.
