Functional description
The SETCON® System consists of a Gearbox incl. differential gear (planetary gear) (1), Servos in combination with a low-voltage Frequency Converter (2+3) and a Control Cabinet (4). The constant power supply is done by an electric motor as the medium-voltage Main Drive (5). The variable ouput is transmitted to a Driven Machine (6) e.g. a Pump or Compressor. The medium-voltage Main Drive (5) is connected directly to the MV-grid and drives the planetary gear’s ring gear at constant speed. The differential gear’s sun wheel transmits the variable speed through an optional high-speed gear unit (offset alignment) to the Driven Machine (6). The differential gear’s planet carrier is connected to the Servos. The speed of the Servos (2) is controlled firstly in order to ensure the speed at the Driven Machine (6) is variable when the speed of the Main Drive (5) is constant, and secondly to control the torque in the entire drive train.
SETCON® FLAGSHIP PROJECT IN GERMANY
• CO2 reduction of app. 12 400 tons per year
• Mechanical and electrical implementation and commissioning within 15 days
• The foundation was not changed and the existing anchor points of the R 18 K 600 were reused
• The constant-speed Main Drive (e-motor) was reused
• No modifications on the Booster pump were required
• The existing lube oil cooler was reused, the working oil cooler was shut down due to the lower losses and reduced oil demand of SETCON
• Neither the BFP nor the Main Drive had to be repositioned on the existing foundation
• Simple and safe integration into the existing control system (through SET’s control system simulation and customer acceptance test in the SET Test Lab)
