Problems solved by technology

Model simulation mainly uses Matlab, PowerFactory, PSCAD and other simulation software to establish models of wind turbines and power grids for simulation analysis. This method is very effective for testing control algorithms and main control programs, but it cannot test real-time performance.
The towed platform test uses the full power of the motor and generator

Description

technical field [0001] The invention relates to the technical field of design and application of a new energy grid-connected detection system, in particular to a wind power controller grid-connected test system based on real-time simulation. Background technique [0002] When large-scale wind turbines are connected to the grid, the fluctuation of their output power during normal operation will cause grid voltage fluctuations. At the same time, the short-circuit current when the wind turbine fails will have a certain impact on the safety, stability and reliability of the power grid. In addition, the current control strategies of wind turbine converters are mainly designed for ideal grid conditions. When grid faults such as voltage amplitude drop, three-phase voltage imbalance, and background voltage distortion occur in the grid, the complete decoupling of the system cannot be obtained. guarantee, the dynamic performance of the control system will deteriorate, and the safe op...
