Technical Study of Real-time Simulation System for Digital I＆C System of Steam Generator in Nuclear Power Plant

The real-time simulation system, which forms a interactive closed circle together with the steam generator control system, has been developed using a dynamic mathematical model of steam generator in this paper. It can provide a simulation target for upgrades of digital Instrument ＆ Control system in Nuclear Power Plant （NPP） and is applicable for further research of control schemes. With this program, the authors have studied and analyzed the response of transient parameters to some different disturbance, the calculated results are in good agreement with those calculated by NPP simulator program. This will give a theoretical analysis for upgrades of digital I ＆ C system in nuclear power plant.
