A centralized monitoring system and monitoring method for a flow battery

Abstract

The invention discloses a concentrated monitoring system and monitoring method of a redox flow battery. Data backup is performed by a server terminal of the monitoring system by employing redundant design, complete storage of data information is ensured; in a network architecture, the independence of a control network and an acquisition network of a battery system is ensured according to a VLAN technology, namely, the acquisition process and the control process are arranged in a branch transmission way; each redox flow battery is basically consistent in parameter type, the parameter of the redox flow battery can be stored by employing a type of a defined structure, namely, frame-type management is achieved, display is performed in a picture, the display of each redox flow battery system isin a way that data is different, different variables are defined by building a template image and changing a mode of a prefix or suffix of a variable parameter, the same picture is only needed to built in one time, the system architecture is enabled to be simple to design by calling a template picture for many times and passing in and out different battery parameters, and the picture number is reduced.

Description

technical field [0001] The invention relates to the field of control of liquid flow batteries, in particular to a centralized monitoring system and monitoring method of liquid flow batteries. Background technique [0002] Liquid flow battery is a new type of clean energy storage device. Due to its technical advantages such as high power, long life, high reliability, low operation and maintenance costs, and support for frequent high-current charging and discharging, it is considered as a solar and wind power generation device. The preferred choice for supporting energy storage equipment, emergency power supply system, power station energy storage peak regulation, frequency regulation, large-scale energy storage of urban power grid, etc. [0003] Among them, the liquid flow energy storage battery system can be applied to all links of the power supply value chain, and can convert intermittent renewable energy such as wind energy, solar energy, etc. into stable power output, and...

Problems solved by technology

[0004] In the control process of the control system of the liquid flow battery in the prior art, due to the need to store and transmit a large amount of data information in the server, the data will be suddenly interrupted and lost during the transmission process; in addition, the control system is in the control process. The terminal adopts one transmission path for information collection and data control of the energy storage device, resulting in the disadvantages of slow data transmission speed and excessive system workload during the transmission process

In addition, in the prior art, the control information in the flow battery control process does not have unified planning management during the display process, resulting in the disadvantage of complicated data display and control.
