Redundant structures are both designed in a parallel connected string unit and a series connected single battery pack of the system, when in failure of single string and single battery which are put into operation, the standby single string and the single battery can be put into the operation without affecting the normal operation of the whole battery system and the battery string, and the maintenance is easy, thereby being in line with the requirements of high reliability of a power system on the battery of the energy storage system.
Description
Technical field
The present invention relates to a kind of battery energy storage system that is easy to safeguard, specifically is a kind of battery structure that is used for the redox flow battery energy storage system of electric power system energy storage.
Background technology
Along with the development of energy storage technology, extensive efficient all-vanadium flow battery energy storage will progressively enter electric power system.Current redox flow battery energy storage system only relies on the simple connection in series-parallel of cell to satisfy the output requirement of high power, big electric current, and when running into fault, the battery reliability of this structure is not high, difficult in maintenance.And the energy-storage battery that applies to electric power system requires its characteristics that have high reliability, are easy to safeguard, therefore, is necessary to design a kind of battery structure of novel all-vanadium flow battery energy-storage system, to satisfy the demand of electric power system.
Summary of the invention
The objective of the invention is provides a kind of high reliability in order to solve the deficiency of present redox flow battery energy storage system structural design, and maintenance easy to use is applicable to the battery structure of the liquid flow energy storage battery system of the extensive energy storage of electric power system.
Therefore, the present invention proposes a kind of redox flow battery energy storage system that is easy to safeguard, it is characterized in that in the single battery group of parallel connection string group neutralization series connection of this redox flow battery energy storage system that all design has redundancy structure.
Its feature of system of the present invention is that also this redox flow battery energy storage system comprises K string battery pack in parallel, wherein every string battery pack comprises N cell of series connection, be provided with at least one reserve battery string in the K string battery pack, also be provided with at least one standby cell in N the cell in every crosstalk pond, K wherein, N is a positive integer, in normal operation, the switch that described reserve battery polyphone is connected on direct-flow positive pole busbar and cathode bus bar all disconnects, but not the reserve battery polyphone is connected on the switch of direct-flow positive pole busbar and cathode bus bar all is closed, when any non-reserve battery string breaks down, in the time of need withdrawing from maintenance, then the battery strings that this is broken down is connected the switch disconnection on anodal busbar and the cathode bus bar, the switch of closed described reserve battery string on anodal busbar and cathode bus bar, thus under the situation of entire cell system operate as normal, syndrome serial is overhauled.
Its feature of system of the present invention also is in arbitrary battery strings, in normal operation, two end switch of described standby cell disconnect, the by-pass switch closure, the two ends switch closure of described non-standby cell, by-pass switch disconnects, when non-standby cell breaks down arbitrarily, two end switch of this non-standby cell are disconnected, the by-pass switch closure, with the two ends switch closure of standby cell, by-pass switch disconnects, thereby under the situation of this crosstalk pond operate as normal the fault cell is overhauled.
Advantage of the present invention is:
Can when the single string that puts into operation, single battery fault, drop into standby single string, single battery, and not influence the normal operation of entire cell system, battery strings, be easy to safeguard, meet the requirement of electric power system energy-storage system battery high reliability.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the integrated circuit structure chart according to system of the present invention;
Fig. 2 is the circuit structure diagram according to the cell of system of the present invention.
Embodiment
The integrated circuit structure chart of foundation system of the present invention is referring to accompanying drawing 1.If this battery system is by K crosstalk pond parallel connection, wherein every crosstalk pond is in series by N battery cell again.The K crosstalk has standby string in the pond, and the single battery in every crosstalk pond has reserve battery again.Suppose that K crosstalk pond is a reserve battery in each the crosstalk pond among the figure, its K switch and K ' that is connected direct-flow positive pole busbar and cathode bus bar disconnects; H crosstalk pond is the battery of operate as normal, and it is connected the switch H and the H ' closure of direct-flow positive pole busbar and cathode bus bar.When moving, H crosstalk pond has been detected fault, in the time of need withdrawing from maintenance, disconnect H polyphone and be connected on two switch H and H ' on anodal busbar and the cathode bus bar, closed K polyphone is connected on two K switch and the K ' on anodal busbar and the cathode bus bar, so just can overhaul syndrome serial under the situation of entire cell system operate as normal.
In like manner, put into operation certain a string in, such as K string, M battery is the battery of operate as normal, two ends K switch MA and KMB closure, by-pass switch KM disconnects, N battery is reserve battery, two ends K switch NA and KNB disconnection, by-pass switch KN closure.When detecting M battery failures, in the time of need withdrawing from maintenance, disconnect its two ends K switch MA and KMB, closes bypass switch KM, N reserve battery put into operation, bypass switch opens KN, closed its two ends K switch NA and KNB so just can be implemented under the situation about normally moving in this crosstalk pond the maintenance to single fail battery.Wherein K, N, H, M are positive integers.
Invention has been described according to specific exemplary embodiment herein.It will be conspicuous carrying out suitable replacement to one skilled in the art or revise under not departing from the scope of the present invention.Exemplary embodiment only is illustrative, rather than to the restriction of scope of the present invention, scope of the present invention is by appended claim definition.
