The availability of lube oil, jacking oil, fuel, ventilation, cooling, turning gear and control systems are essential to overall gas turbine reliability and dependability.

AC UPS and DC Motor based-backup systems are not suitable or reliable backup solutions for rotating loads. KraftPowercon’s Uninterruptible Motor Drives solution UMD™ is the most effective solution to secure pumps, fans and other rotating loads

UMD™ is the most reliable way to power your motor

Supplying motors with the correct power during critical operation means the difference between profit and downtime costs, the difference between running machines and mechanical failures, and the difference between planning ahead and planning urgent field service.

UMD™ systems utilize proven and field tested uninterruptible power supply principles that achieve unmatched reliability.

Full availability

UMD™ provides continuous operation of 3-phase AC motors, with no interruption during utility power disturbances. In normal operation the Variable Frequency Drive (VFD) is supplied from mains. During a brown out or mains outage the VFD is powered from a battery connected directly to the DC-bus of the VFD. The transition between the power sources is completely seamless, meaning no speed drop during any disturbances of the mains supply.

UMD™ adds blackstart capabilities

When a motor operation is backed up by traditional UPS systems, starting up often relies on the availability of utility power. When secured by UMD™, the motors can start up without utility power. This can be done with full torque and full speed as normal start-up. There is no need for a bypass or alternative mains to handle the starting current. Absence of utility power poses no limitations for blackstart.

Complete factory tested UMD™ system

UMD™ is delivered as one complete MCC-unit. Type tested according to IEC, UL, CSA and other applicable standards. The system has single or redundant mains input breakers, battery charger, AC and DC busbars, and the required motor drive outputs. In addition, it can be extended to backup all AC and DC auxiliary loads.

As a result of this several complex engineering activities including battery sizing, power loss calculations, motor protection settings, fuse selectivity in distribution board, can be eliminated. It also allows for fast and straightforward installation and commissioning that can be performed by local technicians.
