Product Center >> Power Automation Systems >> Integrated Automatic System of Substation

Brief introduction
This system mainly applies to the transmission and distribution substation of power system or grid, the substation of a factory power supply system and plant auxiliary power supply system, expansion and renovation of the existing substation etc with 220kV and below voltage grade. It has the advantages of high performance-vs- price ratio, advanced design, stability and reliability, simple operation etc.. The system is a new generation of micro-computer integrated automation system with object-oriented design. It adopts full-opening and hierarchical distributed network structure complied with international standards, and meets the function requirements for automation equipments of international and state grids.
Typical application
These drawings are only as a reference for the system structure, the detailed spacing equipment type and
quantity are determined by the substation scale and function requirement.
