Abstract

The invention provides a generator testing system and method, the generator testing system includes: a transformer, a first frequency converter, a second frequency converter and a generator, the first end of the first frequency converter and the first low-voltage The second end of the first inverter is connected to the first winding of the generator; the first end of the second inverter is connected to the second low-voltage end of the transformer; the second end of the second inverter is connected to the first winding of the generator The two windings are connected; the high-voltage end of the transformer is connected to the high-voltage power supply, so that it is not necessary to use multiple generators to test generators with different levels of voltage, and the generator can be added to full power through only one generator and transformer, so that Complete the task of generator type test, and at the same time, the secondary side of the transformer can output voltages of different levels to meet the type test requirements of generators with different levels of voltage.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a generator testing system and method. Background technique [0002] At present, the power level of wind turbines is developing in the direction of large capacity, and the traditional back-to-back towing method of two generators requires a large amount of power for the test inverter, thus increasing the test cost. [0003] At the same time, the voltage of traditional wind turbines is 690V. Nowadays, there are wind turbines with higher voltages in the market, such as 1140V and 3100V. At present, because the level of wind turbines is 690V, it is impossible to measure higher voltages under the current situation. rated generators are tested. SUMMARY OF THE INVENTION [0004] The embodiments of the present invention provide a generator testing system and method, which can solve the problems of high manufacturing cost of generator testing systems in the prior art and inabili...
