Vehicle-mounted gas turbine generator set and energy storage combined micro-grid system and method

Abstract

The invention discloses a vehicle-mounted gas turbine generator set and energy storage combined micro-grid system and method. The system comprises A-type loads, B-type loads and C-type loads; a guarantee power supply system which comprises an energy storage system, a generator set system and a control system, wherein the energy storage system comprises an alternating current uninterruptible power supply cabinet and a storage battery energy storage cabinet, the generator set system comprises a generator set and a set output power distribution cabinet, and the guarantee power supply system further comprises a commercial power input power distribution cabinet; a commercial power bus and a guarantee bus, wherein the commercial power bus is electrically connected with the commercial power input power distribution cabinet and the C-type load, the guarantee bus is electrically connected with the commercial power input power distribution cabinet, an AC uninterruptible power supply cabinet, the A-type load and the B-type load, and the C-type load is electrically connected with the commercial power bus or the set output power distribution cabinet through a change-over switch; and a remote communication system. According to the vehicle-mounted gas turbine generator set and energy storage combined micro-grid system and the method, a differential emergency guarantee power supply concept is adopted, the generator set system and the energy storage system are integrated, advantages complement each other, benefits are developed, harm is avoided, and on-site emergency power guarantee is ensured.

Description

Technical field [0001] The present invention relates to the field of power generation technology, and more particularly to a microgrid system and method for a vehicle gas turbine generator set and a storage combination. Background technique [0002] my country's energy structure and load characteristics determine the development characteristics of electricity industry as power generation bases, central and eastern part; through long distance, large-capacity transmission channels to connect power generation bases and load centers into my country's main transmission In the form, according to the international accident lessons, this type of transmission is prone to accidents, and the accident is easy to spread, resulting in a large pressure in the load center; in addition, if major political activities in the peak season, it is necessary to conduct major politics Activity is maintained, causing greater difficulties. [0003] In the prior art, through relevant guaranteed equipment is...

AI Technical Summary

Problems solved by technology

[0002] my country's energy structure and load characteristics determine the development characteristics of the power industry in the west and north as power generation bases, and in the middle and east as load centers; the transmission form connecting power generation bases and load centers through long-distance, large-capacity transmission channels has become my country's main transmission form According to the lessons learned from international accidents, this type of power transmission is prone to accidents, and the accidents are easy to spread, resulting in a greater pressure on the load center for peak regulation; in addition, if major political activities are held during the peak regulation season, major political Active power-up, causing greater difficulty

[0003] In the prior art, relevant support equipment is used to ensure power supply for important political activities. However, for temporary meeting places, emergency rescue, competitions, military affairs, international exchanges, and some important scenes that require uninterrupted power supply, fixed uninterrupted Guarantee equipment can no longer meet the current needs of emergency power protection, let alone meet the requirements of mobile power protection

In addition, the existing support equipment usually has a power outage of about 3 minutes after the mains power failure and the generator set is fully loaded, which has a relatively large impact on the general equipment such as air conditioners, elevators, lighting and other equipment on the site Small, but for the data information system operating on site, a momentary power failure will have serious consequences
