The distributed control system(DCS) is the “nerve center” of thermal power unit

but its core software and hardware have a lower localization rate and a higher degree of dependence on foreign countries. In this review

after analyzing the current status of DCS application and localization

the authors outline the design

development and application of the first set of nationally produced DCS in China

namely the “Huaneng Revival” DCS. Aiming at solving the problems of lack of domestic dedicated chips

incomplete functions of analog chips

poor software and hardware adaptability

a main collaborative computing framework with domestic CPU+FPGA as the core is designed

and self-calibration compensation methods based on domestic ADC and DAC chips are developed.Moreover

the software and hardware cooperative fieldbus communication technology based on domestic MCU and FPGA chip is proposed. As a result

fully domestic redundant controllers and I/O modules are developed

with the accuracy of analog modules greatly improved

and the localization of fieldbus technology is realized. The thirdparty test shows the function and performance of the domestic control system meet or exceed the requirements of national and industry standards. The demonstration application of 300 MW and 1 000 MW units shows the research results fully meet the application requirements of large-scale thermal power plants

indicating that China has completely autonomously controlled the production of core control equipment in the power generation field.
