Q1. What is dump load and what is its role in 3000W wind turbine controller?

When the wind is too strong or the generator is under light or no load, the output voltage may exceed the safe range. At this time, the dump load will automatically put into work to increase the load of the generator to reduce its speed and protect the equipment from damage. Read What is a Dump Load for Wind Turbine Controller? for more details.

Q2. What is PWM stepless high-frequency dumping?

PWM stepless high-frequency dumping is an advanced dumping technology that reduces or removes wind turbine loads smoothly and continuously by adjusting the frequency and duty cycle of the PWM signal. Advantages of this technology include fine load control, improved dynamic response and stability of the system, reduction of shocks and mechanical stresses on the grid, and extended equipment life.
