The use of container cranes or shaft hoisting systems for transporting heavy loads necessitates the use of electrical drive technology with powerful motors. In order to precisely and reliably meet the strict requirements of the lifting or conveyor system, power-electronic drive controllers are used for variable torque and speed regulation. Depending on the output and design of the power electronics, a variety of system perturbations can occur that can even trigger malfunctions in neighboring power grids. The most frequent problems in this regard are dynamic reactive power loads, which can cause voltage drops or flicker, as well as harmonic currents or commutation losses.
With individual system solutions tailored to the needs of the customer, Maschinenfabrik Reinhausen is able to eliminate system perturbations, thus ensuring high voltage quality and continuous availability of the crane and conveyor systems.
