The first standard intelligent substation in Shandong Province was put into operation


Recently, the State Grid Corporation pilot project, the first standard distribution-type intelligent substation in Shandong Province - Jining 110 kV Zhongkai substation was successfully delivered once.   Zhongkai station is the first pilot project of standard distribution type intelligent station built and managed by local municipal companies nationwide, and State Grid Shandong Province Electric Power Company requires to create the characteristics and highlights of Shandong. Through the joint efforts of Jining Power Supply Company and other participating parties, the construction task was completed in a short period of 4 months with high standard and quality, overcoming difficulties such as new technology, tight schedule and heavy tasks.   The station broke through the narrow space in the core of the city site selection margin, line corridor


  Recently, the State Grid Corporation pilot project, the first standard distribution-type intelligent substation in Shandong Province - Jining 110 kV Zhongkai substation was successfully delivered once.

  Zhongkai station is the first pilot project of standard distribution type intelligent station built and managed by local municipal companies nationwide, and State Grid Shandong Province Electric Power Company requires to create the characteristics and highlights of Shandong. Through the joint efforts of Jining Power Supply Company and other participating parties, the construction task was completed in a short period of 4 months with high standard and quality, overcoming difficulties such as new technology, tight schedule and heavy task.

  The station broke through the difficulties of small margin of site selection and line corridor tension in the narrow urban core area; it broke the plane layout mode adopted by the previous pilot stations and greatly reduced the floor space through three-dimensional layout, accumulating valuable experience for the construction of standardized intelligent substations of the State Grid Corporation.

  Unlike the traditional electrical layout, civil design and construction mode of substations, the station was built in such a way that the previous mode of assembling and constructing mainly on site was upgraded to the mode of factory prefabrication and modular assembly, and the whole station was assembled on site except for the electrical equipment foundation, earth backfill, road base and building foundation, which required wet work on site.

  This model has a short production cycle, less wet work on site, and less investment in human and material resources; the whole station uses complete sets of electrical equipment, small size, compact structure, safe and reliable operation, easy maintenance and commissioning; the application of plug-in cable terminals, the realization of primary and secondary equipment "plug and play"; compared with the conventional substation construction mode, the whole station Compared with the conventional substation construction mode, the whole station covers an area and the construction period are greatly compressed.

  The station is planned to install 3 sets of 50,000 kVA main transformers, 2 sets are installed in this phase; 2 sets of 110 kV outgoing lines are planned, 2 sets are built in this phase; 36 sets of 10 kV outgoing lines are planned, 24 sets are built in this phase. After the station is put into operation, it will provide reliable power guarantee for Wanda Plaza, a key project of Jining City, and can effectively reduce the power supply pressure of 110kV Dongjiao Substation, which is of great significance to optimize the power grid structure of Jining City and guarantee reliable power supply for urban development.
