HollySys provides customers with entire factory automation solutions. As an important part of the intelligent plant, CCS is an important breakthrough in energy conservation and emission reduction and carbon dioxide emission reduction in the overall industrial process. Realizing the whole process energy conservation and emission reduction and intelligent control can bring huge benefi ts to enterprise users.
HollySys compressor control technology and solutions are based on generator unit control technology and high reliability redundant system software and hardware platform, adopting international advanced compressor control algorithm to ensure safe and effi cient operation of the whole unit, freeing the hands of operators and achieving a full automation solution with high effi ciency and energy conservation.
The compressor anti-surge control algorithm is based on an independent coordinate system to realize the automatic adaptive compensation of the surge line of the unit under different compressor inlet working conditions, solve the problems of distortion of the surge line caused by the mismatch between the compressor design working conditions and the actual operating conditions, and create a prerequisite for the effi cient operation of the unit. At the same time, through the dynamic decoupling algorithm between performance and anti-surge loop, multi-section anti-surge loop, the compressor can be started and stopped with one key, and the compressor can be fully loaded and unloaded. The control strategy can perfectly adapt to the complex process under the condition of ensuring the safe operation of the unit.
The multi-unit series parallel control scheme breaks through the traditional single unit control strategy. While considering the single-unit control, the coordination controller between compressor groups is introduced to coordinate the distribution of the load of each unit, so that each unit can work under the optimal load state, greatly improving the effi ciency of the compressor group, and realizing the fully automated coordinated management of the compressor group.
