Mobile micro-grid system

Abstract

The invention discloses a mobile micro-grid system, which comprises a movable carrier, a transformer arranged on the movable carrier, a prefabricated cabin arranged on the movable carrier, an interface circuit arranged in the prefabricated cabin and a control system for monitoring control of the interface circuit. The interface circuit comprises an AC bus, a DC bus, a distributed resource AC interface electrically connected with the AC bus and a distributed resource DC interface electrically connected with the DC bus. The high-voltage side of the transformer is electrically with an external superior power supply, and the low-voltage side thereof is electrically with the AC bus. The AC bus is electrically connected with the DC bus through an AC / DC module. The system can realize local area power supply, and small-area power balance and energy optimization under the condition where a main network frame is damaged, and meanwhile, meet high power customization requirements of users, such asdistributed resource consumption, uninterrupted power supply and reactive power and power quality compensation and the like.

Description

technical field [0001] The invention relates to a mobile microgrid system, belonging to the technical field of mobile substations. Background technique [0002] At present, power system equipment maintenance and emergency repairs are mostly carried out in the state of power outage. If the operation cannot be carried out in time due to bad weather or other reasons, it is bound to form a long-term power outage, which will cause huge economic losses and negative social impact. Especially in the face of irresistible natural disasters such as ice and snow, floods, thunderstorms and other disasters, the original operation methods and measures cannot fundamentally solve the outstanding contradictions such as the normal supply of power energy urgently needed for disaster relief in a timely and effective manner. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a mobile micro-grid system, which can ...

[0002] At present, power system equipment maintenance and emergency repairs are mostly carried out in the state of power outage. If the operation cannot be carried out in time due to bad weather or other reasons, it is bound to form a long-term power outage, which will cause huge economic losses and negative social impact.

Especially in the face of irresistible natural disasters such as ice and snow, floods, thunderstorms and other disasters, the original operation methods and measures cannot fundamentally solve the outstanding contradictions such as the normal supply of power and energy urgently needed for disaster relief in a timely and effective manner.
