This nuclear power base is the first large-scale commercial nuclear power station on the Chinese mainland, comprising six 1,000 MW-class pressurized water reactor (PWR) units with an annual generation capacity of approximately 45 billion kWh.

The synchronizing and grid-connection system of a nuclear power plant must be designed around the principle of defense in depth, featuring radiation-hardened redundant architecture and intelligent multi-synchronizing-point adaptability, to establish a zero-interruption power assurance system under extreme accident scenarios such as station blackout or earthquakes, while meeting long-term operation requirements in radiation environments.

Since 2007, our company has participated in the construction of this nuclear power base and its subsequent expansion projects. Our synchronizing systems and inrush current suppressors have been successively deployed, helping the plant eliminate dependence on imported critical equipment and resolve key technical challenges encountered during operation, thereby safeguarding the safe and stable operation of the nuclear units.

In practical application, our fully self-developed and independently controllable synchronizing systems and inrush suppressors have replaced imported devices, supporting grid-connection control of 1,000 MW-class PWR units. The equipment demonstrates high stability and strong immunity to high-frequency electromagnetic interference in the vicinity of the nuclear island, providing reliable support for long-term nuclear power operation.
