Wind turbine is an energy conversion device from wind energy to mechanical energy and from mechanical energy to electric energy. The wind power conversion system realizes the energy conversion from wind energy to mechanical energy, and the generator and control system realizes the energy conversion process from mechanical energy to electric energy. When considering the control objectives of the wind turbine control system, the wind operation mode should be controlled and the following control objectives should be achieved:
1. The control system not only keeps the safe and reliable operation of the wind turbine, but also converts the ever-changing wind energy into constant frequency and constant voltage alternating current, which can be transported to the power grid in high quality.
2. The control system adopts computer control technology to monitor and display the operating parameters and state of the wind turbine, and deal with faults, so as to manage and control the best operating state of the turbine.
3, the use of computer intelligent control unit power optimization control. The fixed-pitch and constant-speed turbines are mainly used for soft grid-connection control, soft cutting control and power factor compensation control, while the variable pitch wind turbine is mainly used for optimal tip speed ratio and constant power control above rated wind speed.

The wind turbine control unit (WPCUs) is the control core of each fan and is distributed in the tower and engine room of the unit. Because the operating environment of the wind control cabinet is bad, the reliability of the control system is very high.

The wind control system is designed specifically for the operation requirements of large wind farms. It should have extremely high adaptability to the environment and anti-electromagnetic interference ability, and be capable of autonomous/artificial remote control to achieve the following functions:
1. Real-time operating system control

It can run the complex main control logic of the unit through the field bus and real-time communication with the control cabinet of the engine room, the variable propeller control system, the frequency converter system, so that the unit always runs in the best state.

2. Configuration mode of controller

It adopts the configuration software with rich functions and friendly interface, and adopts the configuration mode conforming to the IEC61131-3 standard.

3. Data parameters collected by wind turbine cabinet control equipment

The signals of temperature, pressure, speed and environmental parameters measured by the sensor of the unit are collected and communicated with the main control station of the unit through the field bus. The main controller controls the frame of the engine room and realizes the functions of the unit, such as yawing and unteaming. In addition, it also controls the various auxiliary motors, oil pumps and fans in the engine room, so that the unit works in the best condition.

4. Touch screen control equipment on site

On-site embedded industrial all-in-one touch screen control unit can allow the field staff to real-time control the wind turbine cabinet control equipment, but also can reflect the running state of the machine, working conditions, etc.

5, remote control monitoring function

The system uses an industrial Ethernet switch to connect a single controller, a touch screen and a remote control center network. A common pair of cabinets is used onsite
Twisted wire connection, and optical cable connection to the remote control room mainframe.

6. Real-time data collection

The real-time feedback of various wind data and power conversion data can be clearly seen on the touch screen. At the same time, intelligent devices can be connected to remotely control the output and conversion rate of the wind cabinet.
