Microgrid power supply system of power distribution station

Abstract

The invention discloses a microgrid power supply system of a power distribution station. The system comprises an inverter, a solar cell panel and a storage battery pack composed of a plurality of storage batteries. The inverter is provided with a cell panel interface electrically connected with the solar cell panel. The inverter is provided with a positive interface and a negative interface whichare electrically connected with the storage battery pack; a mains supply input interface and a power utilization output interface are further formed in the inverter, and when the storage battery is charged by the solar cell panel through a connector protection mechanism, interval type charging operation can be carried out, so that the situation that the service life of the storage battery is shortened due to long-time overcharging is avoided; and meanwhile, through the battery protection mechanism, when the storage battery is overcharged to generate heat or internal short circuit expansion iscaused by long-time use, the charging interface can be quickly disconnected, and battery damage information can be quickly provided, so that further protection and maintenance of the storage battery are realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of distribution stations, and in particular to a microgrid power supply system of a distribution station. Background technique [0002] Distribution station, that is, power distribution station, its task is to send electricity to electrical equipment or users, that is, it can receive, distribute, control and protect electrical energy during use, but it does not transform electrical energy. In order to achieve Distribution and control purposes, so it is necessary to use multiple switches and other components, and it is also necessary to use switch cabinets to install switches and other components when implementing them. Or when the user is unable to power on, they can only use the micro-grid power supply system for power supply, and the micro-grid power supply system is also translated as a micro-grid power supply system. There are many kinds of energy conversion devices used in the microgrid...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a micro-grid power supply system for a power distribution station to solve the problem in the prior art that if the existing storage battery in the power supply system continues to charge after it is fully charged, it will easily cause the internal pressure of the battery. Increase or cause battery expansion and heat, which reduces the service life of the battery
