Distribution Automation System

The XSJ-1600 distribution automation system is developed based on the State Grid's "Technical Guidelines for Distribution Automation" and the "Technical Guidelines for Urban Distribution of China Southern Power Grid," fully adhering to the IEC61970 and 61968 international standards. It is a new generation of intelligent distribution automation system products based on SCADA, with automated management as the core application. The system meets the needs of photovoltaic access, microgrid access, and distributed energy access through flexible configuration and functional expansion.

The XSJ-1600 distribution automation system integrates measurement, protection, control, and remote communication. The system's feeder automation is achieved through both local and centralized methods. The main distribution loop adopts centralized control, coordinated by the master station system, utilizing the communication network for control; branch and radial power supply use local control methods (voltage-type local control, fiber differential local control), achieving rapid control by region. By communicating with the distribution automation master station system, it enables operation monitoring, fault detection, intelligent early warning, fault area isolation, non-fault area self-recovery power supply, and programmed sequential control of distribution and its on-site equipment. The application of the XSJ-1600 distribution automation system helps improve the reliability and power supply safety of the distribution system, reduces personnel and increases efficiency, decreases the outage time and area of the distribution system, as well as maintenance time, enhancing the operation, maintenance, and management efficiency of the distribution system.

Applicable to various urban distribution centers, general urban areas, urban-rural junctions, remote suburbs, rural feeders, and distribution and dispatching in industrial and mining enterprises, the device is installed in various applications such as 10kV switch stations, ring network cabinets, box-type substations, pole-mounted switches, reclosers, sectionalizers, distribution rooms, or distribution transformers.

The complete relay protection performance, using highly reliable network-based optical fiber differential protection and regional network protection design, can quickly achieve millisecond-level fault location, on-site fault isolation, and self-recovery power supply in non-fault areas, as well as second-level self-healing control of distribution network area faults, meeting the high reliability power supply requirements.
