Problems solved by technology

[0003] At present, the existing domestic wind turbine test system generally only has the functions of static debugging and loading test, which can only meet the routine test requirements of the factory test of the unit. Due to the fixed mechanical connection structure in the test system, the drag output power and output The direction is limited, resulting in a single type of unit that can be tested (it cannot meet the test requirements of wind turbines with gearboxes and direct-drive units without gearboxes at the same time), and there are few testable items, and the power of the drag system cannot be adjusted according to needs. Expansion, unable to meet the requirements of diverse test tasks such as key component performance testing, component performance matching testing, wind condition simulation testing, and complete machine testing at the same time, and it is difficult to meet the needs of enterprises in wind power technology research, new model development testing, and different types of units. Urgent test needs in many aspects such as type test, factory test, technology upgrade and transformation

Abstract

The invention belongs to the technical field of tests of wind turbine generator systems, and discloses a multifunctional test system of a wind turbine generator system. The system comprises a generator set, a grid-tied converter and a feed switch cabinet which are sequentially in electric connection, comprises an industrial power grid, a high-voltage switch cabinet, a step-down transformer, a power receiving switch cabinet, a rectifier cabinet and a common direct current bus which are sequentially in electric connection, and further comprises a first inversion cabinet in electric connection with the common direct current bus, a second inversion cabinet in electric connection with the common direct current bus, a first double-shaft-extension dragging motor in electric connection with the first inversion cabinet, a second double-shaft-extension dragging motor in electric connection with the second inversion cabinet and a first coupler used for being selectively connected with a projecting shaft end of the first double-shaft-extension dragging motor and a projecting shaft end of the second double-shaft-extension dragging motor. The system has the advantages of being capable of meeting various test requirements of various common wind turbine generator system models and having high economic efficiency and flexibility.

Description

technical field [0001] The invention belongs to the technical field of testing wind power generators, and in particular relates to a multifunctional wind power generator test system. Background technique [0002] In recent years, wind energy has been widely used as a clean energy source, and one of the effective utilization methods is wind power generation. With the continuous advancement of random wind turbine technology, the single-unit power of wind turbines is increasing. At the same time, the installed capacity and scale of wind farms are also increasing, and the dependence on and influence on the power grid is also increasing. Due to the random fluctuating characteristics of natural wind, which is sometimes absent, the wind farm’s output of electric energy to the grid is also fluctuating, especially when the installed capacity and scale of the wind farm are large, which has a great impact on the stable operation of the grid. Therefore, grid-connected type is required ...
