Dump load controller
For wind turbine installations on markets where legislation claims overproduction may not be distributed onto the grid
Description
Dump load controller for overproduktion
Orbital´s dump load controller is a highly efficient three phase converter right from direct current, DC and overproduction, and peaks from generators will be bypassed to external dump loads.
Orbitals dump load controller solution is being used for wind turbine installations on markets where legislation and grid standards claim that overproduction may not be distributed. This applies to certain types of wind turbine installations in Denmark, Italy and Japan.
The throughput to the dump load controller can be controlled very precise through analog or digitale interfaces. The dump load controller is designet to handle the wind turbines real operation with a latency under 0,5 m/s and up til 1.000 set points per second.
High frequent PWM IGBT switching provides high efficiency with no audible switching noise. Optional inductors can be connected directly to the dump load controller, hereby reducing harmonical current distortions.
