Abstract:
A system for producing electrical energy for supplying electric-motor loads, comprising:a power supply network for supplying the electric motor loads;a plurality of electricity generation sets operating in parallel and supplying in parallel the power supply network via respective outputs;one of a controllable rectifier and a DC voltage controller connected downstream of the respective output of each of the electricity generation sets, the one of the controllable rectifier and the DC voltage controller being coupled to the power supply network to supply the power supply network;a voltage regulator coupled to a control input of the one of the controllable rectifier and the DC voltage controller, an output of the one of the controllable rectifier and the DC voltage controller being coupled to an input of the voltage regulator to supply a voltage actual value signal, the output of the one of the controllable rectifier and the DC voltage controller being coupled to an additional signal generated for sharing a total load between the electricity generation sets so that a supply voltage is reduced as at least one of a supply current rises and power emitted to the power supply network increases.
