Abstract

The embodiment of the invention discloses a hybrid mobile energy storage system comprising a common DC bus current converter topological structure, a supercapacitor room, a battery room and a power distribution room. The common DC bus current converter topological structure comprises battery packs, capacitor banks, a DC bus, a DC / AC current converter and bidirectional DC / DC modules. The bidirectional DC / DC modules are electrically connected with the battery packs and the capacitor banks, and the end which is not connected with the battery packs and the capacitor banks is connected with the DC bus. The battery packs are arranged in the battery room. The capacitor banks are arranged in the supercapacitor room. The DC / AC current converter and the bidirectional DC / DC modules are arranged in the power distribution room. The disadvantages of high noise, high pollution and high operation and maintenance cost of the conventional diesel generator backup power supply can be solved, the defects that the present mobile energy storage system has long power outage switching time and cannot handle the impact load can be solved, and the practicality of the mobile energy storage system can be increased.

Description

Technical field [0001] The invention relates to the field of mobile energy storage and power supply, in particular to a hybrid mobile energy storage system. Background technique [0002] With the development of modern society, the requirements for power quality and reliability of the power supply system continue to increase, and people need a variety of mobile power supply systems to provide additional power supply, temporary power supply, and ensure the stability of the power grid. At the same time, there are many periodic or seasonal loads in the power grid, leading to light load or even no load in some districts most of the time, heavy load or even overload in a certain period of time. At this time, the mobile power supply system can well solve the above problems. [0003] Traditional mobile power supply systems generally use diesel generators as the main power source. Diesel generators use diesel fuel, etc., and diesel engines are used as prime movers to drive the generators to...
