Description

Large-scale energy storage power station black box system based on cloud edge cooperation
Technical Field
The invention belongs to the technical field of operation data record information management systems, and particularly relates to a cloud-edge cooperation-based large energy storage power station black box system.
Background
In recent years, along with the continuous improvement of the economy of energy storage technologies, the energy storage technologies have increasingly outstanding roles in renewable energy power generation, smart grids and energy internet construction, and policies are continuously put out in China to encourage the construction and application of the energy storage technologies. The large lithium battery energy storage power station for centralized application has the characteristics of high power (several megawatts to hundred megawatts), long continuous discharge time (minutes to hours), multiple functions and the like, and is rapidly developed and applied.
The lithium battery energy storage power station is used as novel electric equipment, a large number of lithium iron phosphate batteries are installed in the lithium battery energy storage power station, complete equipment is burnt after a fire event occurs, and great risks exist in the production and operation processes.
The current lithium battery energy storage power station lacks a strong black box system (Event Data Recorder, EDR for short), only has a separated video security system and a fault recording system, and the existing video security system and fault recording system are independent systems and cannot realize complete early warning, fault recording and accident recall functions. The existing video security system does not have an active early warning function, and intelligent early warning protection cannot be performed in the early stage of an accident; the video security system can only record video data, and lacks synchronous recording of the electrical operation data in the single equipment box body, so that data association analysis cannot be performed after an accident occurs; the traditional electric wave recording equipment has shorter wave recording length, thinner covering granularity and is not suitable for lithium battery energy storage power station equipment with long fault period; the Battery Management System (BMS) in the equipment box body has a partial wave recording function, but the wave recording length is shorter, equipment is burnt after a fire event occurs, and the accident recall analysis function cannot be realized.
The current large lithium battery energy storage power station is generally composed of a battery container, a boosting converter container and station control equipment (according to the condition of being in the container or indoor); the main problems in early warning, fault recording and accident recall are as follows:
1. the electrical quantity data, video data, sound data and other data are not synchronously collected, and data association analysis cannot be realized: the current large lithium battery energy storage power station adopts traditional centralized wave recording system equipment of an electric power system, is independently arranged and installed with equipment such as a station controller and the like, is separately arranged with an energy storage container, records waves of electric and partial battery data of the whole station system, can only record waves of faults of the electric quantity of the whole station, cannot record waves of external environment data such as images, sounds and the like in the single battery container, and cannot realize complete accident recall linkage analysis.
2. Aiming at traditional electrical equipment, the fault wave recording system has short wave recording period before fault and insufficient granularity of covering wave recording data during fault, and can not meet the fault wave recording requirement of a lithium battery energy storage power station; the current large-scale lithium battery energy storage power station adopts traditional centralized wave recording system equipment of an electric power system, is based on a large amount of operation data of a lithium battery, has shorter wave recording wavelength, has thinner wave recording data coverage granularity, and cannot meet the actual application requirement on the data volume provided by accident recall linkage analysis.
3. The most easily problematic of current large-scale lithium battery energy storage power station is the battery container, but the battery container does not install the black box, can't realize the comprehensive record of the inside electric quantity of container, environmental data such as video, sound.
4. The existing large lithium battery energy storage power station battery container is internally provided with a shooting and recording all-in-one machine device, and based on the hidden danger of heating and firing of batteries, cables and the like in the battery container, complete equipment is burnt out if a firing event occurs, so that accident recall of the battery container cannot be realized; the network camera NVR is partially adopted, but only has the functions of storing and forwarding data, and cannot realize the acquisition linkage with the data such as electric quantity and the like; and the system also has no AI analysis and early warning function.
5. The lithium battery management system BMS installed in the current part of battery containers has a simple wave recording function, data only exist in the energy storage battery management system BMS, the wave recording length is short, and the data volume provided for accident recall linkage analysis cannot meet the actual application requirements; and if the BMS equipment is burnt after a fire event occurs, accident recall analysis cannot be realized.
6. Based on the scope of non-traditional electric protection actions such as battery faults, connection line faults and the like in the battery container, the time of occurrence is long, the device has the capability of active early warning through internet of things sensing and intelligent analysis, and current wave recording equipment in the industry does not have the function.
7. The fault wave recording system and the video security system in the industry are independent systems at present, and part of video security system equipment has certain internet-of-things sensing and intelligent analysis functions, but no mature scheme technology exists in the industry aiming at battery container industry products.
8. The existing equipment system does not realize decoupling of software and hardware systems, the existing fault recording system is a closed system, and the product upgrading needs to depend on suppliers completely; the cloud edge architecture system is not adopted, or the adopted cloud edge architecture is only data monitoring, and the reasonable division implementation of the machine learning function and the local real-time reasoning function based on the cloud edge architecture is not realized; the system structure lacks applicability and has weaker functions in early warning analysis.
Therefore, a new black box system is needed to solve the defects that the current large lithium battery energy storage power station is limited by the traditional power equipment fault recording system scheme and the video security system scheme.
