全范围模拟机数字仪控系统全仿方案研究

Full Simulation Scheme for Nuclear Power Plant I&C System

全范围模拟机是核电操纵员培训的重要手段.传统的数字仪控系统仿真模拟方法存在着价格昂贵、数据难以采集、进度得不到保证等缺点.研究了一种结合功能模拟和翻译模拟的全范围模拟机数字仪控系统全仿方案,在项目前期采用功能模拟方式保证核电厂操纵员培训进度的要求,而维护阶段采用翻译模拟的方式,使用DCS实际机组的组态工程数据对模拟机进行数据更新.研究结果表明该DCS仿真软件在功能完整、各项性能指标与同类型核电用DCS软件相当,在满足模拟机培训需求的同时节约了成本.

Full-scope simulator is an essential means of training operators in nuclear power plants. The traditional digital instrumentation system simulation method has such shortcomingsas expensive price,difficult data collection and lack of guarantee of the progress.In this paper,a full-range simulation program of full-range simulator and digital instrumentation system combined with functional simulation and translation simulation is studied.In the early stage of the project,functional simulation is used to ensure the progress of nuclear power plant operator training.In the maintenance stage,translation simulation is usedand the configuration engineering data of the DCS actual unit is used to update the data of the simulator. The results show that the developed DCS simulation software is complete in function and the performance indexes are equivalent to those of the DCS software of the same type of nuclear power,which can meet the needs of simulator training and save the economic costs.
