CSDC-800 DC Control and Protection System
The CSDC-800 is a DC transmission control and protection system independently developed by Sifang Co., Ltd. It is applicable to various types of DC transmission projects, including conventional LCC-HVDC, VSC-HVDC, and hybrid DC systems at extra-high voltage (EHV) and ultra-high voltage (UHV) levels.
The system integrates telecontrol and communication, monitoring and supervision, as well as AC/DC control and protection functions. It adopts high-speed real-time communication, efficient distributed task scheduling, and fully graphical configuration technologies, offering features such as high reliability, high performance (10 μs processing cycle), efficient development, easy scalability, strong real-time capability, and convenient operation and maintenance. The CSDC-800 provides a comprehensive secondary system solution for DC transmission projects.
High Reliability and Adaptability
The system adopts a fully redundant design and an embedded hardware platform, providing excellent electromagnetic compatibility (EMC) and environmental adaptability, and ensuring high overall reliability.
Ultra-High Performance and Strong Real-Time Capability
By employing an enhanced multi-core heterogeneous BMP architecture and distributed interrupt coordinated control technology, the system achieves an ultra-fast control and protection processing cycle of 10 μs and extremely low communication latency, significantly improving rapid system response capability.
Efficient Development with Standards Compliance
With the self-developed “Boundless Compiler,” the system supports fully graphical configuration under extremely short execution cycles. This approach is intuitive and highly efficient, and complies with the IEC 61131 international standard.
Flexible Architecture and Easy Scalability
The hardware is designed with standard modules and standardized interfaces, facilitating engineering expansion and upgrades and providing strong adaptability.
Intelligent and Convenient Operation & Maintenance
Based on a scalable multi-level architectural self-describing model and comprehensive internal self-monitoring functions, the system enables online panoramic system monitoring and cross-layer coordinated early warning of latent faults, greatly enhancing operation and maintenance efficiency.
