Coordination control and simulation for small nuclear power plant

Compared with nuclear electric factory, marine nuclear power plant has some particular features including smaller size, faster response, and stronger load following capacity etc. This paper focuses on marine nuclear power plant. Based on static mathematical models of some important parts such as reactor core, steam generator etc., a coordination control system is designed to implement its rapid following and response when power changes. According to the Matlab/Simulink simulation, this new scheme improves fast response capacity of the control system, which contributes to the practical system design.

► Focus on the control of small nuclear power plant.
► Build the multiple models in different working condition.
► A multiple model weighted control scheme is presented.
► The multiple models are more suitable for system control than the original control.
