Simulation analysis method for nuclear power and power grid mutual interference

Abstract

The invention provides a simulation analysis method for nuclear power and power grid mutual interference. The method includes the steps that (1), fundament characteristics of a power grid are analyzed; (2), a research problem sample space needed by nuclear power and power grid mutual interference is selected; (3), transient state and medium and long term simulation analysis is performed. The simulation analysis process comprehensively and efficiently considers the nuclear power and power grid mutual interference after high-capacity nuclear power grid connection. The simulation analysis method not only can cover the transient state process and the medium and long stable analysis process, but also can be adaptive to an actual power grid well. The method facilitates comprehensively and accurately evaluating the power grid and nuclear power mutual interference and security necks after nuclear power access, and the method is of great significance to normal operation of the power grid and a nuclear power source after nuclear power access.

Description

technical field [0001] The invention belongs to the simulation technology of nuclear power grid-connected planning and operation, and specifically relates to a simulation analysis method for the mutual influence of nuclear power and grids. Background technique [0002] Nuclear energy is a modern energy that can replace conventional energy on a large scale. It is clean and economical, and it is not restricted by region, making nuclear power more and more important. Furthermore, the reserves of nuclear fuel for fission energy in the earth's crust and oceans are very abundant. Even if it is relatively conservatively estimated, there will be no shortage of resources due to the application of nuclear power for a long time. Although China's uranium resources are not very rich, the reserves of thorium ore, which can replace uranium as nuclear fuel, rank among the top in the world. Therefore, the rational development and utilization of these nuclear fuels is of great significance f...

AI Technical Summary

Problems solved by technology

At present, domestic nuclear power units have not carried out simulation and analysis of the interaction between nuclear power and power grids during the design and commissioning stages of control and protection systems.

All in all, there is currently a lack of systematic research on the analysis of the interaction between large-capacity nuclear power and power grids considering nuclear power grid integration from the perspective of temporary stability, and in terms of medium and long-term stability, related research work is even rarer
