APPLICATION WIND TURBINES SMART PITCH AND YAW SOLUTIONS EN

KEB AUTOMATION – THE SOLUTION PROVIDER FOR WIND TURBINES Energy transition is one of the most urgent tasks of our time. Only through joint efforts it will be possible to find answers to climate change and to effectively limit global warming. On the way to a more sustainable energy supply that is independent of fossil fuels, wind energy is of key importance. Whether onshore, nearshore or offshore – wind turbines already represent the largest part within renewable energies. KEB Automation alone has equipped more than 40,000 wind turbines with 80+ GW in total with the appropriate drive train...

COMBIVERT P6 – PITCH SOFTWARE SOLUTIONS SOFTWARE PACKAGES AS REQUIRED The P6 internal PLC can be programmed as needed. It comes with a Basic Library for all basic tasks, and the customer can program everything he needs on his own. Or the P6 can be complemented with the Extended Pitch Library, which contains pre-defined function blocks for typical tasks of a pitch system. So the customer just needs to program the interface specific to the turbine. Or the KEB experts can write a Customer-Specific Program for the pitch drive according to the customer’s specification. BASIC LIBRARY EXTENDED...

COMBIVERT P6 – SYSTEM INTEGRATION EASY INTEGRATION OF P6 INTO THE SYSTEM Typically, KEB supplies the core components of the pitch system, as marked in red. The customer makes the cabinet construction and manufactures the cabinet locally; this increases the value added locally. Thus, the mechanical integrationof the pitch cabinet into the nacelle is achieved easily, while the electrical integration into the system is simple due to using the P6. communication CANopen / PROFIBUS / EtherCAT / PROFINET safety chain limit switches, temperatures, analog values P6 charging / monitoring module Pitch...

CONTROLLED YAW SOLUTIONS NON-REDUNDANT SYSTEMS For the yaw drive of wind turbines, KEB can provide different yaw solutions. They all contain: • smooth movement of the nacelle, • torque sharing, • reduction of mechanical load, • reduction of wear of the material. Depending on the system configuration, the yaw drive controllers can also: • tense up the drives against each other, • use the electrical motor brakes instead of a hydraulic brake, • add STO for the safety of service personnel during service operations. REDUNDANT SYSTEMS Used with a multiple inverter solution, the KEB Yaw Library...
