Comprehensively considering the operation cost and safety constraints of nuclear power, an optimal operation scheme of large-scale nuclear power plant participating in peak load regulation of power system is proposed. After quantitatively analysing the peak load regulation cost of nuclear power, the optimal objective is set to minimise the total operation cost including the fuel cost, the start-stop...
The large capacity nuclear power plants have been widely constructed in recent years to cope with social economic development and electrical energy demands. Consequently, it is necessary to be aware of nuclear power plant (NPP) dynamic characteristics in order to study the transient and midterm dynamic process of power system. Due to lacking suitable NPP model which is described the detail characteristics...
In this paper, we propose a dynamic mathematical model for nuclear power plant (NPP) reactor, and give an implementation in Power System Analysis Software Package (PSASP) through a user-defined program. NPP is modeled with a bipartite model that consists of the neutron dynamics module and thermodynamics module. Through the simulation results of NPP reactor under different disturbances, a conclusion...
The nuclear power plants are being constructed and operated widely in recent years. Consequently, it is necessary to study nuclear power plants (NPPs) dynamic characteristics and power system dynamics simulations with nuclear plant after NPPs has been introduced into power system. At first, the paper presents functional description of NPP. Then a detailed and new models of generating plant with PWR...
Established the mathematical modules of pressurized water reactor (PWR) nuclear power plant (NPP) for the studying of the interactions of the power system and the nuclear power plant after its connecting to system, then set up the user-defined model of PWR NPP using the user-defined modules of the Power System Analysis Software Package (PSASP). Calculate the dynamic traits of PWR NPP without regulating...
The simulations of pressurized water reactor (PWR) nuclear power plant (NPP) is a very important domain in the society of nuclear power, and there are several problems with the current PWR-NPP simulations. First, the current physical modeling of PWR is over-simplified which can bring convenience of implementation, while severe inaccuracy is prone to be incurred at some critical situation. Second,...
