Algorithmic configuration is a crucial component of nuclear power plant operation,which can only be completed by drawing design,verification and drawing.In general,the design drawings are converted into algorithm configuration files by manual configuration,which requires high requirements for designers,and needs to check the completed algorithm configuration,so the time cost and construction period are long.In this paper,based on the first nuclear safety level digital control and protection system platform with independent intellectual property rights-"FirmSys",a method of automatic generation of nuclear safety level algorithm configuration is proposed.By defining a standardized intermediate format,the automatic generation of algorithm design drawings to algorithm configuration is realized.This method supports the conversion of different kinds of engineering drawings to algorithm configuration.Through the successful trial in 8 practical nuclear power DCS projects such as Yangjiang nuclear power plant,the automatic generation method is verified.This method accelerates the design cycle,shortens the preparation time of nuclear power plant projects,and provides reference for other industries'algorithm configuration automation.
