On March 16, the Power Science Research Institute of State Grid Shandong Electric Power Company upgraded the advanced technology demonstration platform of distribution automation “one-key CIS control, one-key group control” advanced functional research and development verification capabilities, completed the interactive testing of advanced distribution network self-healing strategy and the practical functions of the new generation of main stations, providing a strong technical guarantee for the practical application of distribution automation in Shandong.

AS-B875-002 For the first time in China, the platform adopts the dual system architecture of “new generation of distribution main station test + distribution automation strategy verification” and has the capability of digital – physical hybrid simulation verification. The platform adopts the latest secondary fusion terminal and a new generation of magnetic control terminal equipment. By adjusting the node switch state, it can realize the flexible deployment and conversion of all typical grids of overhead and cable distribution networks. It can simulate 7 typical FA modes and 336 fault types, and meet the test of distribution terminals and the study of fault self-healing strategies under different operation modes. It provides AS-B875-002 practical basis for developing distribution automation technology for mass distributed power supply access.

AS-B875-002 Relying on the platform, the hospital has carried out functional tests of distribution network intelligent terminals covering double-ring, double-beam multi-grid structures, as well as ground and short-circuit multi-fault types. The “multi-level protection +FA strategy” and intelligent distributed FA strategy based on magnetic control technology are verified, and the strategy research on the combination of relay protection and distribution automation is promoted. AS-B875-002 In addition, relying on the powerful hardware and software facilities and system computing power of the platform, it has tested and improved distribution automation strategies such as chain ball FA, disaster weather emergency treatment, power supply guarantee for important users, and equipment status assessment. After the verification of relevant functions, it has been deployed and applied in the province, improving the fault prevention capability of the distribution network.
