Programme Advantages

System Security

Multiple bypass protection design and full-link control redundancy design ensure no black modules and zero tripping under any circumstances, greatly enhancing the safety and stability of the power grid, ensuring the continuity of power supply, and providing continuous and reliable power transmission to the power grid.
Grid-friendly Design

It features precise voltage and current control, making it ideal for weak grid applications with high levels of renewable energy integration.Through precise control, it balances power fluctuations in the grid, providing strong support for the integration and consumption of renewable energy.
Efficient Operation

The converter valve's overall loss is under 0.6%, significantly improving the system's economic efficiency.Low loss not only reduces energy waste but also cuts down O&M costs, providing strong support for the long-term, stable operation of the power system.
High Reliability

Validation to ensure zero-fault operation in extreme electromagnetic compatibility environments. It is capable of stable operation in harsh environments, providing a solid foundation for the reliability and stability of the power system.
High Controllability

The valve-controlled link delay is at the industry-leading level. The independently developed virtual impedance strategy effectively suppresses the risk of broadband oscillations in the system, adjusts transmission parameters in real time, and ensures the stability and safety of the power system.
Intelligent O&M

The system is equipped with intelligent online monitoring and expert diagnostic functions to achieve unmanned monitoring and intelligent, convenient operation and maintenance.It provides real-time monitoring of equipment operating status, enables timely detection and handling of potential faults, and improves operation and maintenance efficiency and safety.
