The invention discloses a method, device and storage medium for online debugging of DC control system parameters. The method includes the steps of: determining a control parameter list according to debugging needs; modifying a control protection program according to the control parameter list, and providing an online modification and debugging interface for control parameters, In order to obtain the control protection program that can realize online parameter debugging; modify the human-computer interaction interface program according to the control parameter list, so that the human-computer interaction interface provides an interface for online input control parameters and an interface for displaying real-time control parameters; it will be able to realize online parameter debugging Download the control and protection program to the DC control and protection simulation device, and debug the DC system to the initial state of the test; after inputting different control parameters on the interface of the online input control parameters, input the enable signal to enable and complete the control Online debugging of parameters. The invention realizes online modification of specified control parameters by modifying the interface form of the direct current control and protection program, thereby effectively improving test efficiency.
Description
technical field [0001] The invention relates to the technical field of DC control and protection, in particular to an online debugging method, device and storage medium for parameters of a DC control system. Background technique [0002] At this stage, the DC control and protection programs of the DC project are downloaded to the control and protection chassis through solidification and programming. Once a version of the program is confirmed, the control parameters cannot be modified online during operation, especially when it comes to flexible DC. Key control parameters such as the PI link of the inner ring / outer ring are fixed by curing or even internal packaging. [0003] This method provides a guarantee for the stability of on-site operation, but it lacks flexibility for the application of research experiments: in order to optimize the control parameters of a certain control system, it is necessary to repeatedly modify the control protection program, recompile, download,...
