Light water reactor plant modeling for power system dynamics simulation

Abstract

New models of generating plant with the light water reactor (PWR and BWR) have been developed for simulating the plant dynamics under not only the small power system disturbances but also the large disturbances. The developed plant model enables precise and effective analysis of power system dynamics considering the nuclear plant response to power system faults by combining the plant model with the conventional power system dynamics simulation program. This paper first describes the modeling of the nuclear plant, and next outlines the application for power system dynamics simulation with nuclear plant.

Comprehensive Real-Time Hardware-In-the-Loop Transient Emulation of MVDC Power Distribution System on Nuclear Submarine

“…In recent years, a lot of research established the PWR mathematical model [25]- [27] including a detailed PWR linearized mathematical model expressed by 55-order differential equations. In this work, a 21-order differential equation lumped parameter model of PWR is used for power distribution system transient studies purposes, presented mainly in [28]- [31]. This model consists of kinetics model of the reactor, thermal output dynamic system, hot-leg and cold-leg temperature model, steam generation model, reactor control system model, and turbo-generator set model, as shown in the Fig.…”

Optimal feed-water level control for steam generator in nuclear power plant based on meta-heuristic optimization

“…The dynamic model, representing the PWR typical components is mainly based on the fundamental principles; conservation of mass, energy, and momentum. The approach of modeling NPP dynamics for studying the interaction between grid and NPP has been early proposed (Ichikawa & Inoue, 1988;Hu et al, 1993;Gao et al, 2006;Arda et al, 2013;Tan et al, 2013;Arda & Holbert, 2014;Wu, Ju, et al, 2016). Complete dynamic models of different components of a NPP connected to infinite bus system are summarized in the following subsections.…”

Study on the Different Dynamic Models and its Simplified Standards of the PWR Neutron

“…In 1983, the EPRI in United States designed proposed PWR linear model based on small disturbance hypothesis [6]. In 1988, CRIEPI in Japan designed a model of light water reactor (LWR) nuclear power plants for power system analysis [7]. After 7 years, the EPRI and CRIEPI jointly proposed a detailed model suitable for analysis of power system long-term stability.…”
