Function: The voltage generated by wind turbines is usually low (several hundred volts to several thousand volts), and the voltage needs to be raised to a high voltage level suitable for long-distance transmission through a booster transformer (such as tens of thousands of volts to hundreds of thousands of volts).
Location: These transformers are usually installed inside a wind turbine or in a boost station on a wind farm.
Type: Common transformer types include dry-type transformers and oil-immersed transformers. Dry-type transformers are often used in wind power plants because of their safety and low maintenance.
2. Collector system transformer
Function: Wind farms are usually composed of multiple wind turbines, which are brought together by a collector system, and the transformer of the collector system will uniformly process and adjust the output voltage of different generators.
Configuration: These transformers need to be able to handle the overall output power of the wind farm and transmit the power to the main substation.
Function: Grid-connected transformers convert high-voltage power from wind farms into voltage levels suitable for grid transmission, ensuring that power can be safely and reliably connected to the grid.
Requirements: These transformers need to be highly efficient and stable to cope with the intermittency and volatility of wind power generation.
Characteristics and requirements
High performance and low loss: Transformers must have high performance and low loss characteristics to maximize power transmission efficiency.
Environmental adaptability: The transformer must operate stably in an outdoor environment and have the characteristics of moisture, dust, and corrosion resistance. Especially in the harsh environments of wind farms, the reliability and durability of transformers are critical.
Intelligent management: The modern transformer integrates an intelligent monitoring system, which can monitor the operating status in real-time, conduct remote management and maintenance, and improve the reliability operation and maintenance efficiency of the system.
