Beschreibung
Zusammenfassung:	The invention discloses an LCC-HVDC inverter valve current prediction method, and belongs to the technical field of LCC-HVDC inverter valve current prediction, and the method comprises the steps: carrying out the preprocessing of the obtained to-be-predicted LCC-HVDC inverter three-phase current data, and obtaining the useful data of the three-phase current; and inputting three-phase current useful data into the trained deep learning inversion model to obtain valve current predicted values of three valves on the LCC-HVDC inverter. According to the method, the corresponding relation between the three-phase current and the valve current is established, the valve current waveform with relatively high accuracy can be obtained without accurately analyzing and calculating the coupling inductance of the converter transformer and the 12-pulse two bridges, the accuracy of the obtained valve current waveform is more accurate along with the richness of samples, and the result is more accurate, so that the workload is gr
