CYG STATCOM supports various control modes including constant reactive power, constant voltage, and constant power factor. It is widely applicable in transmission systems, distribution networks, new energy power generation stations, as well as industrial fields like electrified railways and steel smelting. It serves to stabilize voltage, improve power factor, suppress harmonics and flicker, thus effectively enhancing the power quality and supply reliability of the grid. The system design features "N-1" redundancy capability and integrates comprehensive multi-level protection functions to ensure safe and stable operation of the equipment.
The core controller adopts the latest floating-point controller in the industry, with high main frequency, large memory capacity, and high computing and control accuracy.
Utilizing innovative intra-chain and inter-phase balance algorithms, it effectively controls DC-side capacitor voltage equalization without additional hardware, reducing system complexity and losses.
Professionally designed modular power units with compact structure, high reliability, and easy production and maintenance; The originally designed hot standby redundancy can ensure that the redundant unit switches to operation with zero impact when the operating power unit fails.
It has flexible communication methods, supporting power industry communication standard DL/T667-1999 (IEC60870-5-103) and the new generation substation communication standard IEC61850, with excellent communication performance.
The system features integrated wave recording, capable of capturing fault transient processes at up to 9.6kHz, or continuously recording steady-state conditions at 1Hz~1.2kHz, facilitating analysis and reproduction.
