Assembly integrated substation compared with the traditional substation differences and advantages?

In recent years, with the continuous and sustained development of social and economic, core power demand continues to grow, in order to meet the electrical load, improve the ability to supply power, the State Grid Corporation put forward the construction of a strong intelligent grid requirements, so the voltage level of the intelligent substation came into being. The rapid development of the construction industry and electrical installation Xiangneng Chutian Power also makes it possible to build quality, efficient and intensive assembly integrated substations.

The civil construction of the assembly-type integrated substation fully embodies the characteristics of "assembly type" and adopts the prefabricated steel structure construction mode. Substation walls, gates, structural supports, equipment supports, etc. are all assembled using a combination of assembled steel structure, all steel components in the factory prefabrication, industrialized, large-scale production, technical uniformity, standardization of specifications. When all steel structure production is completed, it will be directly transported to the construction site for lifting and assembly to complete the intensive construction.

The traditional substation using reinforced concrete structure, the construction process has a concrete ready-mixed, pouring and maintenance, formwork installation and demolition, bedding production and pouring, steel transportation and tying, etc., work is complicated, labor consumption, the required period of time is long. In addition, the construction and maintenance of concrete structure is greatly affected by the level of operators and the weather, so the construction quality and schedule are not easy to be fixed, and the pouring and transportation are easy to cause environmental pollution. Compared with the traditional substation steel mixed structure civil engineering, assembly integrated substation due to the use of factory processing, standardized production, modular production, modular combination, with a short construction cycle, less field work, good quality standards, environmental protection and convenience, etc., to save land resources, production intensification, shorten the construction period, so that the substation construction towards the high-tech refinement of the construction of the road.

Assembly integrated substation in the civil and electrical installation in the full use of "assembly time" process, change the traditional substation construction mode, the intelligent substation according to the factory production of prefabricated, on-site assembly and installation of the two phases of construction. Intelligent integrated substation in the construction of prefabricated steel building components, integrated assembly of electrical equipment and control cables and a series of new technologies, reducing the workload of the construction site, so that the construction cycle is shortened, the quality can be controlled, the cost of labor is reduced, and the quality and environmental protection benefits are improved. The commissioning of the assembled integrated substation will make a positive contribution to the upgrading of the grid construction level and the promotion of a solid smart grid construction.
