Abstract

The invention provides a novel megawatt wind generating set testing system and a testing method thereof. Energy provided by a power system provides electric energy for a double shaft-extension dragging motor by a series of devices; then the dragging motor drives a tested set to operate by a series of devices such as a wind wheel simulator and the like; and the electric energy generated by the tested set is returned to a distribution transformer by a series of devices so that energy feedback is realized. The tested set can simulate the characteristics of a wind turbine under different wind conditions by means of the wind wheel simulator and the output characteristics of the tested set can be detected by the testing system. Meanwhile, the low voltage ride through (LVRT) performance of the tested set can be tested by arranging an LVRT device in the feeding link. The system has the advantages of electric energy saving, flexible configuration and wide applicable power range, capability of testing the control performance and the output power characteristics of the tested set, capability of detecting the low voltage ride through (LVRT) capability of the tested set by adopting the LVRT device, strong compatibility and expansibility and capability of knowing the testing conditions on site in time and meeting multidirectional testing requirements.

Description

technical field [0001] The invention belongs to the field of wind power generation equipment, and relates to a new megawatt-level wind power generation unit test system and its test method, which can meet the current domestic test requirements of various 0-5.6MW wind power generation units, and can test the key components and systems of the whole machine Carry out tests and detect unit power curve, low voltage ride through, power quality, etc. Its design standard is high, advanced and economical. 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 increase of the power of wind turbines and the continuous optimization of product structure, the types of generators are also continuously upgraded, and asynchronous generators, doubly-fed generators, electrically excited synchronous generators, and permanent magnet generators have appear...
