WT1500 Wind Turbines

Based on standard design, WT1500 Series doubly-fed wind turbines form several types (plateau type, plain type and low wind speed type) through the configuration of turbines and the personalized customization and in-depth optimization of functions and parameters according to the complex characteristics of the geographical environ- ment at different wind farms. They have excellent low-voltage ride-through capacity and friendly grid adaptability, and various indexes are shown excellent after operation of many years.

Main Performance And Characteristics

Friendly grid design and excellent power generation performance

  1. Excellent power quality and total current harmonic distortion rate of less than 1% under the rated power;

  2. Convenient energy management platform, and efficient active power and reactive power regulation ability;

  3. Great improvement of power generation performance through the use of blades with excellent aeroperfor- mance and in combination with a number of advanced control technologies.

Compact unit design

  1. Compact doubly-fed water-cooled converter, reasonable nacelle layout and large maintenance space;

  2. Small size, light weight and convenient for transportation.

Modular design of environmental adaptability

  1. According to the environmental conditions of specific wind farm projects, various modular solutions such as prevention from low temperature, condensation, salt erosion, sandstorm, thunderstorm and ultraviolet radia- tion are configured;

  2. The design complies with the requirements of the new IEC standard, and the unit has high safety performance.
