Generator test system

Abstract

The invention provides a generator test system which comprises a control unit, a detection unit, a tested generator, a direct current motor and a direct current motor driving unit. The system is characterized in that: the system also comprises a load generator, wherein the tested generator, the load generator and the direct current motor are in coaxial connection; output of the tested generator and input of the load motor are connected to provide electric energy input for the load generator; the direct current motor driving unit connects with the direct current motor and is used for driving the direct current motor; the detection unit connects with the tested generator and is used for detecting a parameter of the tested generator; the control unit is used for sending a control signal to the direct current motor driving unit in order to control running of the direct current motor. According to the test system, a power feedback method is employed, electric energy generated by the tested generator in a test process is sent to a generator which is taken as a load of the tested generator, environmental protection is facilitated, system composition is simplified, thus a failure rate is reduced, test accuracy is raised, test cost is reduced, and enterprise competitiveness is enhanced.

Description

technical field [0001] The present invention relates to a generator test system, particularly a generator test system using a power feedback method, wherein no separate resistive or reactive load is required. Background technique [0002] All kinds of generators need to undergo strict inspection and testing before leaving the factory to ensure that they meet various standards, such as GB 755-2000 Basic Technical Requirements for Rotating Electrical Machines (corresponding to IEC 60092 Marine Motors), GB / T 1029-2005 Three-phase Synchronous motor test methods (corresponding to IEC 60034, TOCT 11828 and other foreign standards) and GB / T 1029-91 general technical conditions for marine generators, etc. Moreover, due to the uniqueness of some generators, such as wind turbines, marine generators, etc., after they are put into operation, once they fail to work due to potential problems, maintenance is very difficult. Therefore, the factory test of generators is particularly importan...

Problems solved by technology

In the prior art, it is not easy to test high-power generators, and it is necessary to use relatively large-scale equipment to drive the generator under test, which increases the difficulty of testing

The traditional method is to use a prime mover with sufficient power to drive the generator under test to generate electricity, and the electric energy generated will be dissipated in the form of heat by heating the heating element such as the resistance wire as the load, and a large amount of energy is consumed in the whole process (such as: fuel oil, electric energy, etc.), the output electric energy is also wasted, which is not conducive to energy saving and environmental protection, and also increases the production cost of the enterprise

Moreover, the tested generator needs to be connected to a separate load, and the equipment connection is also complicated
