Development of Calculation Software of Steady State Parameters for HVDC Transmission

Abstract:

As the ± 800kV Xiangjiaba-Shanghai UHVDC pilot demonstration project has been completion production in China, an UHV AC and DC power era is coming in State Gird. A large number of calculations of main circuit steady state parameters for HVDC system are necessary for both HVDC transmission planning and design and checking DC projects in operation. Therefore, this paper firstly discusses the steady state parameters. Then considering the comprehensiveness of types of HVDC transmission, through digesting design features of foreign similar software, the steady state parameters calculation software for HVDC transmission is developed independently. It has features such as user-friendly interface, real-time calculation and calculation of comprehensive, rapid and accurate, using the mixed programming of Visual C++ (VC++) and MATLAB. Finally, take the ± 800kV Xiangjiaba-Shanghai UHVDC transmission project for example to calculate steady state parameters. The calculation results are accurate to meet the engineering requirements.
