A dragging motor is sequentially connected with a torque meter and a gear box, the gear box and a hub of a wind power generation unit to be tested are connected through a coupling, a wind regime simulation device is in signal connection with a wind power test control system, a second power converter is electrically connected with a generator of the wind power generation unit to be tested, and the wind power test control system is electrically connected with a power-grid power distribution cabinet, a test power transformer, an electric switch cabinet, a first total power converter, the dragging motor, the torque meter, the gear box, a pitch control system on the hub of the wind power generation unit to be tested, a yaw system of the wind power generation unit to be tested, a low-voltage through simulation device, the second power converter and a test checkout system. According to the invention, tests such as a total power test, a yaw test, a pitch control test, a grid-connected power generation test and the like of various wind power generation units in a large power range can be realized.

Description

technical field [0001] The invention relates to a megawatt-level wind simulation test system and a test method. Background technique [0002] Wind energy is a kind of pollution-free green energy. The development and utilization of wind energy and the vigorous development of wind power generation technology are of great significance for solving the global energy crisis and environmental pollution. For wind turbines, although the most convincing test method is still the field test in the wind field environment. However, in the development and product testing of wind turbines, a multifunctional wind force simulation test system that can simulate the actual wind conditions of the wind field and can adapt to various wind turbines is still very much in demand. [0003] There are many different types of generator test systems and test methods in the existing wind power technology, but the test of high-power wind turbines basically follows the traditional generator test mode, grid-...
