| Abstract:In order to efficiently complete the preliminary design of DC converter stations and realize the optimization of technical and economic indicators， and improve the competitiveness of domestic technical schemes in overseas projects， taking ± 500 kV DC project as an example， this paper studies the scheme of the standardization and optimization of the primary electrical design of DC converter stations. Based on the analysis of the standardized design schemes of electrical wiring， equipment selection， plane layout and floor area of the AC filter field， converter area and DC field， the capacity and group number of the equipment configuration are reduced through the design optimization of main circuit parameters. The engineering configuration and equipment redundancy configuration is reasonably reduced according to the characteristics of the engineering scheme and technological development progress. According to different equipment selection， the corresponding plane layout is matched to realize the optimal design of the overall scheme. The comparative test results show that the total width of the AC filter field of the optimized electrical design scheme can be reduced by about 32 m， and the vertical layout of the converter can reduce the size of the long side of the valve hall， and the configuration of two groups of DC filters can reduce the floor area of the DC field and reduce the size by about 12 m. The unit capacity cost of the optimized overall project is 603 yuan / kW， which is 12.6% lower than the original scheme. |
