Abstract

The first ±800kV UHVDC transmission system is connected with the East China power grid around 2010 and its maximum transfer capacity will reach to 6.4GW. It brings new challenges and impacts on the network structure, operation security and reliability and system stability. In the paper, East China power gird configuration and load level for 2012 is adopted as base case for study. The power system simulation tools, such as PSS/E, BPA, etc, are used to study the system security and reliability under conditions of typical UHVDC operation modes. Technical issues associated with impacts of the ±800kV UHVDC connection on voltage stability, power transfer capability (ATC), system reliability are particularly studied. Some useful conclusions and suggestions for transmission system planning, operation security and stability considering the UHVDC connection are drawn in the end.
