Description

Technical field [0001] The invention relates to a performance test simulation platform for a frequency conversion controller of a double-fed wind power generating set, and belongs to the technical field of new energy equipment performance testing. Background technique [0002] The doubly-fed wind turbine is currently the mainstream model of most wind farms in operation or under construction in the world, and the inverter controller is the core component of the doubly-fed wind turbine, and its performance directly determines the equipment of the wind farm Safety and operational efficiency. The function of the variable frequency controller is mainly reflected in two aspects: one is to realize the variable speed and constant frequency control of the mechanical energy conversion of the doubly-fed wind turbine; the other is to realize the ride-through capability of the wind turbine to reach the standard when the grid low voltage fails. The traditional method of performance test of fr...

Problems solved by technology

The traditional method of testing the performance of variable frequency controllers is purely physical (physical) model tests, but physical tests have high manpower and material costs, long cycles, low efficiency, and poor equivalence of physical models to the overall system, so it is still not possible to carry out targeted frequency conversion.
