A multi-donor area flexible interconnection system

Abstract

The invention discloses a multi-supply area flexible interconnection system, which includes a regional energy dispatching station, a user-side intelligent interconnection collection terminal, an off-grid intelligent control device, and a mobile energy storage supply station; the regional energy dispatching station is used to receive users The power consumption information on the user side and fully dispatch mobile energy for supply and regulation; the user-side interconnection collection terminal includes a centralized control cabinet, a smart meter installed in the centralized control cabinet, a load metering device, a temperature and humidity sensor, and a wireless transceiver terminal. The smart meter, load metering device and temperature and humidity sensor send data to the regional energy dispatching station through the wireless transceiver terminal for analysis and formulate a dispatching strategy; the off-grid intelligent control device includes the battery manager, bidirectional inverter transformer, isolation transformer, and off-grid switching cabinet; this solution can quickly regulate the ambient temperature of the energy storage system and automatically extinguish the fire, ensuring the safe, stable, and efficient operation of the energy storage system.

Description

technical field [0001] The present invention relates to the technical field of smart grid power supply, in particular to a multi-supply area flexible interconnection system. Background technique [0002] The development of power grid technology has faced four major problems: First, the relationship between source and load. At present, the power grid is still a semi-rigid power grid in which the source follows the load. However, the lack of market allocation and demand-side linkage means makes it a dormant resource, and the source-load relationship urgently needs to be changed from unilateral passive to two-way interactive. Second, in terms of redundancy, grid equipment quotas and margins cannot be released, which restricts the improvement of efficiency; equipment operation standards lack effective evaluation in changing environments, relying on high redundancy to ensure grid security, and urgently need to change from increasing redundancy to ensuring safety to reducing redun...

Problems solved by technology

[0004] The purpose of this invention is to solve the problem that the charging and discharging failure of the energy storage system in the mobile power supply vehicle affects the power supply of the station area, and proposes a multi-supply area flexible interconnection system. It is mainly manifested as the problem that the solder pads fall off due to the high temperature of the terminal, and the local temperature caused by the short circuit is too high to cause combustion or explosion), using the silicon wire to sense and conduct the temperature of the sensitive part, and then through the metal deformation. The strain force-driven flow regulating device adjusts the flow rate of cold air and dynamically controls the temperature. At the same time, it can save the cost of liquid nitrogen and achieve a good temperature regulation effect. When a fire occurs, the fire extinguishing device can be automatically turned on for fire extinguishing
