A wind-turbine-blade-pitch system for a wind turbine comprises at least one electric motor which can be configured to be addressed by an inverter. The inverter can be configured to be addressed by a rectifier. The rectifier and the inverters are configured to be arranged locally separated from each other in the wind-turbine-blade-pitch system. The power distribution device and at least one power-storage system are connected via one or more electrical supply lines. The power distribution device can be configured to supply the at least one electric motor with electrical energy from the power storage system, via the one or more electrical supply lines.
