Pitch Drive

Pitch inverter COMBIVERT P6

Specially developed for use in electrical pitch systems, the COMBIVERT P6 meets all the requirements for rotary use in the hub of wind power facilities with the prevailing local vibration and temperature loads.

In active operation, the electrical system output and speed of the hub are controlled by the rotor blade position. In case of failure of the turbine itself or in the supply network, the pitch inverter fulfils the task of protecting the wind power facility against dangerous overspeeds or brings it to a halt by fast turning of the rotor blades away from the wind.

COMBIVERT P6 is an active part of the wind  turbine safety system, certified by TÜV Rheinland. In safety operation of the entire pitch system, consisting of three COMBIVERT P6, the solution achieves "Performance Level d" according to EN ISO 13849-1. The P6 hence meets the requirements of "GL Guidelines for the certification of wind power facilities (2010)" - a key basic requirement for establishment in the European market.
A current unique feature of the COMBIVERT P6 is the high level of integration of the inverter, the loading device for the energy storage system and a fully adequate PLC - all in a highly compact format.
This design means that the P6 is flexible and adaptable to a wide range of customer requirements, without having to provide individual system know-how.

The COMBIVERT P6 is therefore highly flexible and widely adaptable. Easy installation also helps reduce costs and sources of error in processing.
