Microgrid power storage control system for guaranteeing elevator power supply

Abstract

The invention provides a microgrid power storage control system for guaranteeing elevator power supply. The microgrid power storage control system comprises a main network controller, a large power grid alternating current bus and N microgrids, the M microgrids further comprise storage batteries, wherein M is larger than or equal to 1 and smaller than or equal to N; under charging states,the storage batteries acquire electric energy from the microgrids; under discharging states, the storage batteries discharges electricity to the microgrid alternating current bus; the main network controller is connected with microgrid controllers; the main network controller is used for obtaining the power of the large power grid alternating current bus and large power grid load in real time, wherein thelarge power grid load is the sum of load power of the microgrids in a grid-connected state; and the main network controller is used for controlling charging and discharging of each storage battery according to a comparison result of the power of the large power grid alternating current bus and the large power grid load. According to the microgrid power storage control system for guaranteeing elevator power supply, through electric quantity balance of a large power grid, the microgrids and the storage batteries, normal power supply of an elevator is guaranteed, and the power failure risk of theelevator is avoided.

Description

technical field [0001] The invention relates to the field of micro-grid technology, in particular to a micro-grid power storage control system for ensuring elevator power supply. Background technique [0002] In modern society, electronic products are becoming more and more abundant, and people's lives are increasingly inseparable from electricity. With the increase of various electrical appliances, the burden on the power grid is getting heavier and heavier. [0003] In this case, various microgrids emerge in endlessly. In order to improve the anti-risk ability of the micro-grid, the grid-connected technology of the micro-grid emerges. [0004] As a means of transportation for high floors, elevators are even more indispensable in cities. In order to ensure the normal operation of the elevator and not be affected by city power outages, the elevator must be equipped with an independent power supply system. However, an independent power supply system is not only expensive,...

Problems solved by technology

[0005] However, at present, when there is a fault in the microgrid, such as insufficient power supply, if the large grid after grid connection cannot bear it, the microgrid can only go off the grid and bear it alone Fault

In this way, the large power grid cannot effectively solve the fault problem of the microgrid
