Embodiment approach

[0133] Method 1: The long-term power supply method of the main power supply of the island small reactor nuclear power plant;

[0134] Method 2: The long-term power supply method where the main power source of the nuclear power generation ship docks on an isolated island;

[0135] Mode 3: The main power source of the nuclear power generation ship is powered by the energy storage system.

[0136] The three implementation modes can be implemented independently and are not related to each other. For the case of a large island load, the power supply method of method 1 or method 2 can be used; for the case of a small island load, the power supply method of method 3 can be used.

[0137] Method 1: Long-term power supply method for the main power supply of the isolated island small reactor nuclear power plant

[0138] Such as Figure 9As shown in , it shows a schematic diagram of the overall control principle of the system in Embodiment 1 of the present invention.

Abstract

The invention discloses an island integrated energy supply and safeguard system. The system includes a small-sized nuclear power generation device which serves as a main power supply of an island micro-grid; a switch station which is intended for connecting the small-sized nuclear power generation device to the micro-grid; a high capacity energy storage system for energy storage and a super capacitor; a distributed regeneration power generation system which serves as an auxiliary power supply of the island micro-grid; a diesel power generation system which serves as an emergency energy source of the island micro-grid; and a micro-grid integrated control management center system; the mall-sized nuclear power generation device, the switch station, the high capacity energy storage system, the distributed regeneration power generation system, the diesel power generation system, and the micro-grid integrated control management center system are connected through power transmission lines or / and micro-grid communication lines. According to the invention, the system can provide integrated energy supply and safeguard.

Description

technical field [0001] The invention relates to the technical field of microgrids used in isolated islands, in particular to an integrated energy supply and guarantee system for isolated islands. Background technique [0002] Microgrid is an organizational form of distributed power generation. It is a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads and monitoring systems, and protection devices, which can realize self-control, protection and management. , it can run in parallel with the external power grid or run in isolation. An island microgrid refers to a microgrid that only has independent operation functions, such as a microgrid that supplies power to remote areas or islands. [0003] The isolated island system is usually far away from the land and the island area is relatively small. The long-term diesel transportation and consumption costs restrict the development o...
