Problems solved by technology

However, this solution needs to configure a large-capacity battery pack, which has high cost, short life, and is not easy to maintain.
Moreover, the diesel engine is large in size, slow to start, and loud in operation. Compared with the diesel engine, the gasoline engine has improved in the above aspects, but both the gasoline and diesel power generation costs are relatively high, and the power generation efficiency is not high.
At the same time, this scheme requires long-term storage of a large amount of fuel oil, which poses a...

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] See figure 1 As shown, it is a schematic structural diagram of a preferred embodiment of a sustainable power supply, energy-saving and environment-friendly uninterruptible power supply system of the present invention, including a unit starting device 1, a gas-fuel dual-fuel engine 2, a small generator 3, a rectifier module 4, an inverter Variable module 5, charging and discharging module 6, battery pack 7, selection switch 8 and control module 9.

[0033] See figure 2 As shown, the three modules of unit starting device 1, dual-fuel engine 2, and small generator 3 constitute a generator unit. When the mains power is abnormal, the unit starting device 1 starts the dual-fuel engine 2 to drive the small generator 3 to work. Generates backup power for an unlimited duration.

[0034] See image 3 As shown, the rectifier module 4...

Abstract

The invention discloses an uninterrupted power system (UPS) capable of continuously supplying power, which comprises a power generator set unit, a UPS unit, a selection switch (8) and a control unit (9), wherein the power generator set and the UPS unit form a standby loop which is respectively connected with loads through the selection switch (8), when a mains supply loop (11) is abnormal, the control unit (9) controls the selection switch (8) to be switched into the mains supply loop (11) for providing standby power to the loads, thus uninterrupted power supply is realized. According to the invention, under the condition of main supply failure, the UPS can be switched to a standby power generator for supplying power, so that the uninterrupted power supply for residual families is realized; and meanwhile, a duration-free sustainable energy-saving environmental-friendly power supply mode is met.

Description

technical field [0001] The invention belongs to the field of uninterruptible power supply, and in particular relates to an uninterruptible power supply system for sustainable power supply, which is especially suitable for power consumption in scattered residential areas in remote cities and suburbs (such as power supply for villas). Background technique [0002] With the development of society, social life is increasingly inseparable from electricity. However, power cuts are very popular when the summer electricity consumption peaks. At the same time, energy conservation and emission reduction, characterized by power cuts, often sweep across the country. In addition, due to uncertain factors such as natural disasters and extreme weather, there will also be unexpected power outages in the power grid. The sudden power outage brought great inconvenience to residents' lives. [0003] In order to solve the above problems, UPS (Uninterruptible Power Supply, uninterruptible powe...
