It is the new generation of intelligent distribution network "self-healing" system developed by CYG ET based on IEC 61968/IEC 61970 and the latest related standards. By collecting all kinds of distribution network information within its coverage, it can realize the functions of distribution network operation monitoring, operation status control, distributed electrical connection and control, self-healing control, economic optimization operation, etc., and achieve the purposes of enhancing power supply reliability, improving distribution network line loss, power quality, power supply capacity and management level and reducing operation cost. The system adopts service-oriented software architecture, which can well meet the needs of system integration and continuous development of application; The system has a high-speed real-time library with millions of measuring points, a high-speed information interaction bus and DMS/DTS integrated application, which can realize the information interaction of safe cross-regional collaborative management and control; Construct a master station system characterized by "informationization, automation and interaction".
