Main control system is the control core of wind turbine

but its domestic independence is very low

and the external dependence is relatively large

which is the weakest link in wind turbine equipment. On the basis of analyzing the current situation of localization of wind power main control system

the design

development and application of Huaneng Revival Wind Power PLC system was introduced. It is the first batch of 100% domestic wind power main control systems in China. Aiming at solving the problems of poor software and hardware adaptability and lack of CAN open modules

a domestic wind power PLC module with core chips such as CPU and FPGA was designed

and the domestic CAN open communication module was developed. Test by an authoritative third party shows that it has fully met the actual needs of functional performance and reliability indicators of the localized wind power main control system of wind turbines. The demonstration application of onshore 2 MW

offshore 5 MW wind turbines and the batch application of onshore 1.5 MW wind turbines show that

the wind power main control system has strong real-time performance

high environmental adaptability and anti-electromagnetic interference capabilities. It fully satisfies the application requirements of various wind turbines

indicating that the control core of wind turbines in China has achieved full autonomy and controllability.
