核电厂DCS模拟机中数据回放技术的设计与实践

在核电厂操作员培训时，为了使教员能检测操作员的操作过程是否正确，需要分散控制系统（DCS）模拟机具备数据回放功能。该功能是模拟机与实际DCS最大的区别，也是模拟机实现的难点。本文论述了数据回放技术的设计与实现方法，通过对系统中的数据、事件、鼠标键盘操作分别进行存储和查询来实现数据回放的目的。该技术已经在核电厂DCS模拟机产品SpeedySim中实现，并在阳江核电站5号、6号机全范围模拟机系统中得到了良好的应用，可以推广到其他模拟机产品和模拟机系统应用中。 

Design and Practice of Data Replay in DCS Simulator of Nuclear Power Plants

In the training of the nuclear power plant?operators, the Distributed control system(DCS)?simulator is required to have the data replay function, so that?the trainer could monitor the operator's operation. This function is the main?difference between the simulator and the actual DCS system, as well as the main difficulty to implement the simulator. This?paper fully discussed the design and implementation of the data replay?function, and the data replay?function is realized through storing and querying the system data, events, mouse and keyboard operation in the system. This technology has been realized in SpeedySim, which is the DCS simulator product for?the nuclear power plants, and it has been applied in the full scope simulator system in unit?5?and 6?in Yangjiang?Nuclear Power Station.?This technology can be promoted for?the application of other simulator products and systems.
