Xiongan is a place engraved with "smart genes" everywhere.

As of April 1, 2024, the first batch of new generation centralized control systems undertaken by State Grid Corporation of China-Xiongan Rongdong new generation substation centralized monitoring system undertaken by NARI Group Power Grid Company and NARI Research Institute-has been operating safely and stably for two years.

Rongdong Centralized Control Station is the first substation centralized control station in China to simultaneously apply a new generation substation centralized monitoring system and digital twin technology. The substation centralized control station is the "clairvoyance" and "easy ear" of power grid operators. It adopts "integrated monitoring, panoramic display, data penetration, sequence control operation call, paperless operation, comprehensive error prevention, intelligent alarm, automatic acceptance" 19 key technologies, establish a unified model system, realize integrated panoramic monitoring of main and auxiliary equipment, comprehensively improve the monitoring intensity and management fineness of substation operation and maintenance, and improve work efficiency.

At present, Rongdong Centralized Control Station has been connected to two 220 kV substations and four 110 kV substations to protect the operation of the Xiongan New Area power grid.

Power grid dispatch is equivalent to the "brain" of the power grid and the "central nervous system" that controls the entire power grid. At present, NARI Group has built power grid dispatching control systems used by more than 80% of the country's power grid control centers. Based on long-term technical accumulation and rich construction experience, NARI Group has carried out research and development of a new generation scheduling technical support system.
