In case of modeling HVDC transmission

RT-LAB has the advantages of accurate simulation result

high simulation efficiency and low cost.However

the research on the model by the use of RT-LAB is rare both at home and abroad.The application of real-time simulation technology in UHV DC transmission is studiedbasedonthe RT-LABreal-time simulation platform and taking the Ximeng-Taizhou±800kV UHVDC project as the background.The module classification of the system is performed firstly in accordance with the functional block of RT-LAB and each module is modeled independently.During the modeling process

the model control part is set up by the custom modeling method.Finally

the model is discretized by the ARTEMIS solver of RT-LAB.The accuracy of the model is verified by the comparison of the steady state and transient simulation results of the model with the data given in the engineering design book.The simulation result shows that the proposed modeling method can effectively model the HVDC transmission system

which is of great significance for the modeling of HVDC transmission based on RT-LAB.
