Product Details

The COMBIVERT P6 was developed specifically for electrical pitch systems, and meets all the requirements for rotary use in the hub of wind power facilities with consideration of prevailing 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 over speeds, 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 requirement for 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.
