Siemens Large Drives Applications (LDA) to deliver a high voltage (HV) motor with 105 MW and a 40 MW starting frequency converter for an energy storage project in China. The motor will have an efficiency of beyond 98 percent
Siemens LDA has received an order from a Chinese customer to deliver a special machine with dual shaft extension. It can be used in motor operation with a power of 105 MW and as generator with up to 129 MVA in power generation mode. The motor will have an efficiency of beyond 98 percent and will be a world-leading 2-pole electric motor.
Beside the motor, the contract includes the delivery of a 40 MW Sinamics GL150 starting frequency converter. This LCI-converter (load commutated inverter) is designed for single-motor applications with variable and constant torque characteristics. As a result of the low switching losses and the low loss thyristor technology, the efficiency of the LCI converter is extremely high and lies at 99 percent.
