Microgrid system with movable hydrogen energy emergency power supply

Abstract

The invention provides a microgrid system with a movable hydrogen energy emergency power supply. The microgrid system comprises a moving unit and a fixed unit detachably connected with the moving unit; the moving unit comprises a first fuel cell power generation unit, a storage battery, a first interface and a second interface which are connected to a direct current bus; the first interface is used for being connected with a hydrogen storage system stored with hydrogen, and the second system interface is used for being connected with a small turbine generator system (LLS) of a nuclear power plant, so that the moving unit serves as an electric emergency power supply for a factory; the fixed unit comprises a power generation unit detachably connected with a direct current bus, a DC / AC bidirectional converter unit connected to an alternating current bus, a load power supply unit, a grid-connected switch and a hydrogen production device; the first direct current bus is provided with a third interface and a fourth interface, wherein the third interface is used for being detachably connected with the DC / AC bidirectional converter unit; and the fourth interface is detachably connected with a photovoltaic power generation unit. According to the microgrid system, the defects existing in the existing electric emergency power supply of a nuclear power plant factory are overcome, and the nuclear safety can be greatly improved.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a microgrid system with a mobile hydrogen energy emergency power supply. Background technique [0002] For the field of nuclear power, nuclear safety is of great significance. In order to ensure nuclear safety, the plant power supply of nuclear power plants needs to be highly redundant, such as conventional emergency diesel generators, mobile emergency diesel generators, LLS small steam engines and batteries, etc. However, in case of special circumstances, it is necessary to ensure that the plant power supply of the nuclear power plant is normal, so the nuclear power plant must have a plant power emergency power supply. At present, most of the emergency power supplies for power plants use traditional fossil fuels. The continuous consumption of traditional fossil fuels (such as coal, oil, and natural gas) will cause serious energy shortages and global environmental problems. It is...

Problems solved by technology

At present, most of the emergency power supplies for power plants use traditional fossil fuels. The continuous consumption of traditional fossil fuels (such as coal, oil, and natural gas) will cause serious energy shortages and global environmental problems. It is imminent to develop new renewable energy sources. Some existing Renewable energy technology solutions have certain limitations. For example, wind energy is greatly affected by the environment and climate, and there are intermittent and random problems. The grid connection will have an impact on the grid; another example is ocean energy (tidal energy, wave energy, temperature difference energy) There are great limitations at the geographical and technical levels; another example is that solar energy can only generate electricity when there is sunlight, there are intermittent and random problems, and grid connection will have an impact on the grid
