The main control system has important control and protection functions for the wind turbine, such as turbine start and stop, yawing, rotor speed control, grid connection and disconnection, fault stop, untwisting, recording and monitoring. The character of the main control system is: advanced technology, high safety and reliability. The main control system is the brain of the wind turbine, controlling all the components to work in a coordinated manner. The main control system is divided into the tower base control system, the nacelle control system and the generator control system, which communicate with each other via the fieldbus.
The main control system mainly consists of industrial controller (PLC), industrial sensors, low voltage components, etc. It collects all kinds of sensor data in real time and communicates with the pitch system, converter and other sub systems to ensure the smooth and safe output of the wind turbine. Through the core control algorithm and core control logic, it maximizes the performance of the wind turbine under the premise of the turbine safety and stability and maximizes the benefits for the users.
Key features:
- It provides local and remote human-machine interface, supports a variety of industrial communication protocols, monitors and records the grid, wind conditions and turbine operation in real time, and uploads raw data to the remote monitoring system for wind farm management.
- Adaptive yaw control
- Rotor speed control
- Optimal wind energy capture based on air density
- Intelligent power rating boost
- Peak load shaving technology
- Pitch control
- Gust control
- Turbulence control
- Lidar feedforward control
- Tower vibration control
- Drive chain damping control
- Anti sweep tower control
- Anti rain erosion control
