Controller

A complexity of control functions is required to ensure smooth operation of a wind turbine. FREQCON has developed an integrated control system with unified data interface and communication protocol. A consistent software is programmed based on IEC61131 standards. All subsystems have access to measurement values of the complete system to optimize operation mode. This reduces the number of sensors and avoids problems with data communication and data consistency.

Data communication is based on PROFINET, a reliable high-performance fieldbus system with real-time communication. This system allows not only control of standard functions like hydraulic, yaw, cooling, lubrication, HMI etc., but also time-critical functions like pitch-control and triggering of IGBTs, all through one centralized controller.

A secure data protocol version also allows integration of our modules for vibration- and speed monitoring as well as cable-twist sensor and overcurrent protection.
