Features
- The FEC1150 cabinet comprises all devices needed to build up a converter system
- Pulse rectifier and inverter based on IGBT modules on water-cooled, easy-to-change power stacks
- DC-link made of film-capacitors
- Break chopper and break resistor
- Controller boards linked via fast bus system (EtherCAT)
- Grid main contactor and precharge-circuit
- Generator-side filter (du/dt) and grid-side filter
- Heat exchanger air-to-water for cooling of all passive parts: cabinet has IP54
- The concept is suitable for electrical as well as permanent magnet excited synchronous generators and also valid for asynchronous generators
Main advantages
- The main advantages can be summarised as follows.
- Combines high power density with reasonable costs.
- Protection class and cooling type allow offshore use.
- All serviceable parts are easy to replace.
- Reduced grid current harmonics.
- New control algorithm allows managing symmetric and asymmetric voltage drops.
