HollySys provides Power Plant Integration Solutions for the construction of a new generation of power plants based on digitization and informatization. Its whole-plant integrated solution covers the entire processes including boilers, steam turbines, auxiliary machines, desulfurization and denitrification. It provides optimized control algorithms for superior boiler combustion efficiency, thereby improving the comprehensive utilization efficiency of primary energy and reducing pollutant emissions. Fujian Hongshan's 1000MW ultra-supercritical coal-fired generating unit control system is provided by HollySys. This is currently the largest thermal generating unit project with the most powerful control capacity in China designed with fieldbus technology. The HollySys control system provided to the Hequ Power Plant of CHN Energy Shenhua Group successfully controls a supercritical circulating fluidized bed. Meanwhile, HollySys has numerous successful cases in the control of power plant isolated network operation.
