Abstract

The invention discloses a wind-photovoltaic-diesel-storage integrated AC / DC off-grid microgrid integrated controller, which comprises a busbar, a plurality of photovoltaic controllers, a wind-power DCjunction box, a diesel-power DC switching box, and a diesel-power automatic start-stop control distribution box. The photovoltaic controllers are connected with a photovoltaic array group. The wind-power DC junction box is connected with a wind-driven generator through a wind-power controller. The diesel-power DC switching box is connected with a diesel-power AC distribution box through a diesel-power DC stabilized power supply, and connected with a diesel generator through the diesel-power AC distribution box. The diesel-power automatic start-stop control distribution box is configured to transmit a diesel-power automatic start-stop control distribution current signal to the diesel-power AC distribution box. A light assessment current transformer is disposed on the busbar behind all thephotovoltaic controllers. A total metering current transformer is disposed at the rear end of the busbar. A diesel-power voltage transformer is arranged between the diesel generator and the diesel-power AC distribution box. The tail end of the busbar is connected with a plurality of battery packs and a communication equipment group for wireless remote communication with the outside for remote monitoring, metering, and remote meter reading.

Description

technical field [0001] The invention relates to an off-grid microgrid controller, in particular to an integrated AC / DC off-grid microgrid integrated controller with wind, diesel and storage. Background technique [0002] The photovoltaic power generation system uses photovoltaic panels as power generation components, and regulates and controls the generated electric energy through the controller. On the one hand, the adjusted energy is sent to the DC load or AC load, and on the other hand, the excess energy is sent to the battery pack. Storage, when the generated electricity cannot meet the load requirements, the controller sends the electric energy of the battery to the load. After the battery is fully charged, the controller must control the battery not to be overcharged. The controller must control the battery from being over-discharged and protect the battery. The battery can store energy to ensure the load's power consumption at night or in rainy days. However, the exi...
