Distributed control system(DCS)

as the core control system in the field of thermal power generation

its software and hardware have heavily depended on imported products for a long time. And the risk of chip outage brings great hidden dangers to the safety and production of power plants. Based on the study on current situation of DCS software and hardware of domestic brands

this paper analyzes the necessity of localization substitution for realizing independent control

and puts forward that the realization of DCS localization is not just a simple hardware substitution and software transplantation

but should focus on solving the problems of special chip substitution

chip function defects

software and hardware adaptation and comprehensive computing power. The development and application status of full-domestic DCS

such as HN Revival

Huadian Ruilan

Guoneng Zhishen

Nanjing Keyuan and Zhejiang central control technology

is introduced. The autonomous and controllable DCS has been put into operation successively in 300 MW

600 MW and 1 000 MW units

marking that China's DCS has achieved complete autonomy and controllability

and has the conditions for large-scale promotion and application. Finally

the paper also analyzes the problems encountered in the promotion and application process

such as lack of embedded lowpower processor

batch differences in the performance of domestic components

the cost performance of domestic software and hardware and supply chain security

and puts forward relevant suggestions.
