The output of the wind turbine is variable frequency power, and a variable frequency power test system should be used to measure the variable frequency power.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a heat fluid. work.
The principle of wind power generation is to use wind energy to drive the rotation of the blades of a wind turbine, and then use a speed multiplier to increase the rotation speed to to encourage the generator to produce electricity. According to current wind turbine technology, electricity production can startr at a breeze speed of around three meters per second (the breeze level).
