[0029] Example 1
[0030] The automatic test method for the pitch-changing backup power supply of a wind turbine of the present invention is used to automatically test the pitch-changing backup power supply of each wind turbine in a wind farm, and includes the following steps:
[0031] (1) Compare the system time with the data of each unit, where the data of each unit is the time node (cycle) when each unit needs to test the pitch backup power supply. With the increase of time, the time node of the test should be shortened accordingly. After comparison, if a certain unit needs to perform a pitch backup power test, a request for a certain unit to be tested will be sent.
[0032] The above time nodes can be set according to the model, performance parameters and operation and maintenance manual of the pitch backup power supply of each wind farm unit.
[0033] (2) Obtain the operation safety-related data of a certain unit according to the test request, and judge whether the unit ...

[0039] Example 2
[0040] An automatic test device for the pitch backup power supply of wind turbines is used to automatically test the pitch backup power supply of each wind turbine in a wind farm. In the form of a functional module framework, it includes:
[0041] Test request module: Compare the system time with the data of each unit. The data of each unit is the time node (cycle) that each unit needs to perform the pitch backup power test. After comparison, if a certain unit needs to perform pitch backup Power supply test, send a request that a certain unit needs to be tested. The above time nodes can be set according to the model, performance parameters and operation and maintenance manual of the pitch backup power supply of each wind farm unit.
[0042] Safety judgment module: According to the test request, obtain the operation safety-related data of a certain unit, and judge whether the unit is in a safe state now. If the unit is in a safe state, it will issue an autom...
