The invention relates to a direct-current power grid test model used for power grid interconnection. The direct-current power grid test model comprises a land new energy direct-current power grid DCS-A and a direct-current power grid DCS-B which are connected through a high-voltage direct-current power transmission line. An alternating-current system A connected with the land new energy direct-current power grid DCS-A and an alternating-current system B connected with the direct-current power grid DCS-B carry out bi-directional power transmission through the direct-current power grid test model, and asynchronous or synchronous interconnection is realized. The technical scheme provided by the invention can be used for researching the application of a direct-current power grid in cross-regional new energy grid connection, asynchronous power grid interconnection or synchronous large power grid construction, the scale of the model is suitable, and the universality is good. 本发明涉及种用于电网互联的直流电网测试模型，包括通过高压直流输电线路相连的陆地新
