We are thrilled to announce the first-attempt grid synchronization of CRRC’s 100MW/50.41MWh Independent Energy Storage Project in Ruicheng, Shanxi, China. As a core component provider, #NebulaElectronics deployed its self-developed Nebula 3.45MW Centralized PCS, achieving safe, efficient, and first-attempt grid integration for this landmark initiative. This milestone demonstrates Nebula’s advanced technology and strong strength, setting a new benchmark for global energy storage deployments.
As CRRC’s first large-scale flywheel-battery hybrid storage project in China, the system includes a 110kV booster station ,50MW/50MWh lithium battery + 50MW/0.41MWh flywheel ESS. It provides critical primary frequency regulation services, enhancing regional grid stability.
Nebula 3.45MW PCS: Global-Grade Performance
Deployed 15 units to manage the battery storage system, featuring:
- Maximum 1500V Operating Voltage
- High Power & Rapid Current Rise with Low Current Harmonic
- Support Multi-Unit Parallel Operation
- Multi-mode control : CV/CC/Constant AC/DC Power
- Support VSG, LVRT/HVRT Ride-Through, Black Start & Anti-Islanding Protection
