Research and Application of Electrical System Simulation Calculation in Nuclear Power Plants

The electrical system equipment structure of nuclear power plants is complex and diverse, but the degree of digitization and intelligence is relatively low. The calculation processes such as electrical system simulation analysis, short-circuit calculation, and equipment selection rely on manual labor, resulting in low work efficiency and easy human error. Building a simulation computing platform for the electrical system of nuclear power plants can carry out efficient digital simulation computing work, such as digital short-circuit calculation, constant value setting, constant value accounting, equipment selection, design verification, simulation analysis, fault analysis, fault handling, etc. Based on the network topology characteristics, load characteristics, and power flow calculation functions of the nuclear power plant electrical simulation model, a graphical modeling of the power plant electrical system is carried out. Proposed to center around engineering data. By driving the workflow through data flow, the digitization of electrical systems is achieved, reducing human intervention and ensuring efficient and accurate design changes, fault analysis, and handling processes.
