Why String-Type PCS Containerized System ?

We take all aspects of your project into careful consideration during the design phase
Fire safety

String-Type PCS Containerized System is engineered with safety as a top priority, featuring an advanced immersive fire suppression design at the PACK level. In the event of thermal runaway in a single cell, the affected PACK is instantly flooded with cooling liquid, effectively extinguishing the fire at its source while preventing spread to adjacent PACKs—ensuring both precision and containment. The system is equipped with a Kentec fire control panel, a globally recognized brand approved by fire authorities across multiple countries. This enables seamless integration with local fire protection systems, ensuring smooth acceptance and compliance during installation and inspection.

ANY PORT SCADA

String-Type PCS Containerized System integrates FFD POWER’s proprietary ANY PORT SCADA system, enabling a parallel communication architecture between local and remote control units. By connecting the Siemens PLC, PCS, BMS, and TSO (Transmission System Operator) interface to a unified gateway, the system can simultaneously support local control logic and remote dispatch. Meanwhile, the Siemens PLC ensures local safety interlocks and control logic remain fully functional and secure. This architecture guarantees both fast external responsiveness and robust local reliability.

Single Cluster Management

The String-Type PCS Containerized System adopts a Single Cluster Management architecture, where each battery cluster operates independently under its own control unit. This design virtually eliminates inter-cluster circulating currents, significantly extending battery life. Independent cluster operation ensures that a fault in one cluster won't compromise the entire system, enhancing uptime and simplifying maintenance. The number of clusters can be flexibly configured at the design stage to meet specific capacity requirements, delivering a solution that is both technically robust and economically optimized.

Multi function

String-Type PCS Containerized System features a multi-functional PCS designed to operate under three configurable modes: PQ mode for active/reactive power control VF mode for voltage and frequency control (grid-forming) VSG mode for virtual synchronous generator behavior This flexibility enables the system to support black start and grid-forming functions, while also delivering ultra-fast grid-following performance in PQ mode—responding to frequency and power regulation signals within 200 ms, ideal for applications such as peak shaving and frequency response services.
