For more conveniently understanding the implementation process of the present invention, refer to fig. 2, which is a simplified flow chart of an ac fault ride-through characteristic online debugging method according to an embodiment of the present invention, and fig. 2 can more clearly understand the implementation process of the present invention. In addition, the control protection function of the program run by the compact modular dc control protection simulation device is consistent with the function of the actual dc system control protection program.
Specifically, because the existing dc control protection program of the dc engineering is downloaded to the control protection chassis in a curing programming manner, and cannot modify the control parameters online, to implement online debugging of the parameters, the control protection program of the compact modular dc control protection simulation device is modified according to the test parameters to provide a test parameter online modification debugging interface, obtain the control protection program capable of implementing online parameter debugging, and complete the early-stage technical support work.
And downloading a control protection program capable of realizing online parameter debugging to the compact modularized direct current control protection simulation device, and debugging the direct current system to the initial test state. The initial state of the test is generally set according to the requirements of research test.
And modifying the test parameters into a first group of test parameters by modifying the debugging interface on line through the test parameters, and setting the alternating current fault so as to carry out a first alternating current fault ride-through test. The test parameters comprise KP parameters of a current inner loop PI control link, control input quantity of an outer loop, cut-off frequency of a filtering link and the like.
Judging whether the tests of all the test parameters are finished or not, if so, ending the tests; if not, then the first step is executed,
and modifying the test parameters into the next group of test parameters by modifying the debugging interface on line through the test parameters, and judging whether the state at the moment is the initial state of the test. The judgment of whether the test initial state is to ensure that the direct current system carries out the next test in the test initial state and eliminate the influence of the test state on the test result.

and when the state is not the initial test state, debugging the direct current system to the test state again, performing the next alternating current fault ride-through test, and continuously judging whether the tests of all the test parameters are finished after the test is finished.
That is, after the next ac fault ride-through test is completed, it is determined again whether the tests of all the test parameters have been completed. If all of the comparative tests have been completed, the test ends.
In the online debugging method for the ac fault ride-through characteristic provided in embodiment 1 of the present invention, online modification of different test parameters is implemented by modifying the form of the dc control protection program interface, and optimal debugging of dc control system parameters related to the ac fault ride-through characteristic is implemented, so that not only is the research and test efficiency effectively improved, but also the test deviation caused by starting the system to a specified working condition for many times can be reduced.
As an improvement of the above solution, the test parameter online modification debugging interface modifies the test parameters by the following steps:
and downloading each group of test parameters to the control protection program capable of realizing online parameter debugging through the test parameter online modification debugging interface.
Specifically, each group of test parameters is downloaded to a control protection program capable of realizing online parameter debugging through a test parameter online modification debugging interface.
For example, the compact modular direct current control protection simulation device is connected with a human-computer interaction interface, an input interface for inputting test parameters is added on the human-computer interaction interface, the test parameters to be modified are input on the input interface every time the test parameters need to be modified, and then an enable signal is input to enable, so that the alternating current fault ride-through test is completed.

when each alternating current fault ride-through test is carried out, the alternating current fault ride-through characteristics of the direct current system are observed and relevant test data are stored; the alternating-current fault ride-through characteristics of the direct-current system comprise a ride-through result, key electrical quantity characteristics and recovery speed.
Specifically, when each alternating current fault ride-through test is carried out, the alternating current fault ride-through characteristics of a direct current system are observed and relevant test data are stored; the alternating-current fault ride-through characteristics of the direct-current system comprise a ride-through result, key electrical quantity characteristics and recovery speed. The purpose of observing the AC fault ride-through characteristic of the DC system and storing related test data is to compare the influence of different test parameters, so that the AC fault ride-through characteristic can be better understood.
As an improvement of the above scheme, after modifying the test parameters to the next set of test parameters by modifying the debug interface on line through the test parameters and determining whether the state at this time is the test initial state, the method further includes:

and if the AC fault ride-through fails, debugging the DC system to the test state again.

and the debugging module is used for debugging the direct current system to the test state again when the state is not the test initial state, then carrying out the next alternating current fault ride-through test, and continuously judging whether the test of all test parameters is finished after the test is finished.
6. An apparatus using an ac fault ride-through characteristic online debugging method, comprising a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, wherein the processor, when executing the computer program, implements the ac fault ride-through characteristic online debugging method according to any one of claims 1 to 4.
7. A computer-readable storage medium comprising a stored computer program, wherein the computer program, when executed, controls a device in which the computer-readable storage medium is located to execute the ac fault ride-through characteristic online debugging method according to any one of claims 1 to 4.
