Introduction When the wind turbine is no-load, the voltage is very high, but there is no current. Why does the motor burn out? Wind turbines are generally designed as constant power generators (mechanical power obtained from the wind blades).

When the wind turbine is no-load, the voltage is very high, but there is no current. Why does the mo

Wind turbines are generally designed as constant power generators (mechanical power obtained based on the blades). When the blades rotate, the mechanical power is constant and the generator power is constant, according to P=UI. P is a constant. If there is no current, the voltage will be very large, which will break down the insulation layer of the generator and burn out the motor. . . Hahaha

In wind turbines, when it comes to the opening voltage of the motor, is it measured on the stator or the rotor? The 14 tests include but are not limited to insulation resistance test, ground resistance test, transformer test, circuit breaker test, isolating switch test, transformer test, capacitor test, reactor test, arrester test, transmission line test, distribution line test, Power plant testing, wind power generation testing and photovoltaic power generation testing. These tests are designed to ensure that new energy equipment can operate safely and stably when connected to the grid, and comply with relevant power standards and regulations.

This is the voltage on the rotor side of the double-deficit converter. The magnitude of this is related to the inverter side of the converter. It is not clear what the impact will be if it is too high. If it is too high, it will at least damage the motor rotor. The insulation withstand voltage is generally not very high. Normally, it is around 300-400V. The opening voltage of the rotor is determined by the excitation current of the inverter and the rotor speed resistance.
