Test platform and test method for wind generating set control cabinet

Abstract

The invention discloses a test platform and a test method for a wind generating set control cabinet, and the platform comprises a power supply module which is used for supplying power to the tested wind generating set control cabinet and the test platform thereof; a PLC, communicated with the power supply module, the to-be-tested wind generating set control cabinet and the simulation test module, and used for communicating with the to-be-tested wind generating set control cabinet and performing online control; a simulation test module, used for simulating a wind field environment and comprising a yaw motor, an anemograph, a wind indicator, a rotary limit switch, a vibration sensor, a temperature sensor and a 4-20mA signal generator, and the wind field environment being simulated by rotating the anemograph, the wind indicator and the rotary limit switch and shaking the vibration sensor to test the control cabinet of the wind generating set; and a door plate indicating lamp and button module, communicated with the PLC so as to display the operation mode of the test platform and realize button control. According to the invention, a wind field operation state is simulated in a wind generating set control cabinet factory for testing.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a test platform and a test method for a control cabinet of a wind power generator. Background technique [0002] The in-factory test of the wind turbine control cabinet is basically the detection of the electrical components and electrical circuits in the cabinet, and basically does not consider the test of the actual operating state of the wind farm. However, when the wind turbine is running in the wind field, various failures will still occur, so the test of the control cabinet of the wind turbine to simulate the operating state of the wind field in the factory is particularly important. [0003] At present, the in-factory test of the wind turbine control cabinet basically uses the ohm gear of the multimeter to test the channel of the control cabinet, and then powers on to measure the voltage. If only these two parts are measured, the following points cannot be tested when...

[0006] 3) The communication status of the wind turbine control cabinet cannot be tested

[0007] If the above several parts of the test are not tested in the wind turbine control cabinet factory, then it is easy to burn the electrical components when debugging in the wind field, and when encountering electrical circuit problems, it is necessary to check the wind turbine control cabinet end, and also need to check the wind power generation. The electrical execution end of the unit, which is time-consuming and labor-intensive
