This medium voltage drive has been in stable operation on-site for over three years and has withstood multiple grid voltage sags of varying severity.The power cell fast automatic bypass design and the Low Voltage Ride Through (LVRT) capability of Nancal Electric's medium voltage drives address internal cell failures and external grid voltage sags, respectively, effectively preventing unplanned shutdowns caused by such issues.
Unplanned shutdown is the costliest "silence" on a production line. Faced with the high price of unexpected stops, how can a medium voltage drive leverage its high reliability to reduce the risk of unplanned shutdown? Read on to discover Nancal Electric's solution.
A well-known domestic chemical enterprise planned to implement an energy-saving, emission-reduction, and capacity-expansion project for its polycarbonate production unit. This included converting the originally steam-driven MVR steam compressor to electric drive. The MVR steam compressor system was originally driven by a high-speed steam turbine (referred to as the steam turbine), directly connected to the drive shaft of the high-speed centrifugal compressor. The NC HVVF series medium voltage drives provided by Nancal Electric delivered excellent high-frequency drive performance and system safety control performance for the high-speed PMSM in this MVR steam compressor "steam-to-electric" retrofit project of a polycarbonate production unit, providing highly reliable and sustainable technical support for the project retrofit.
Nancal HVVF series drives can be used in constant torque control such as conveyor. The key control performance is to realize the coordination between multi-motors.
