Power system simulation is an important tool that guarantees safe and stable operation of multiple HVDC weak sending power grids of a large energy base. In this paper a transmission and distribution grid panoramic simulation laboratory is developed based on power system simulation demand

while applying advanced simulation technology for distributed and open deployment. Through a specialized power wide area network

resource-sharing advantages are realized among departments of business application. The engineering application in this work demonstrates that a resource-sharing laboratory for collaborative operations is able to satisfy the requirements of multiple directions

scenes

and angles of the transmission and distribution power grid.
