A kind of intelligent control accumulating system and method with real-time cell batteries monitoring function
Technical field
The invention belongs to storage battery electric power storage and accumulator monitoring technical field thereof, be specifically related to a kind of intelligent control accumulating system and method with real-time cell batteries monitoring function.
Background technology
At present human society from industrialization, electrified to the modernization development process; The particularly introducing of new forms of energy and popularization; The application of accumulating system and reserve DC power supply more and more widely; As the storage battery of accumulating system and reserve DC power supply important component part, the good and bad state of its performance condition just seems particularly important for the normal operation that guarantees accumulating system and reserve DC power supply.Along with accumulating system and reserve DC power supply, especially maintenance free cell is widely used, and problem displays gradually, for example:
Most of maintenance free cells compare the much shorter of wanting of expectation useful life;
Indivedual storage batterys fall behind or inefficacy causes whole Battery pack to lose efficacy;
After storage battery was installed, lack of scientific, effective monitoring management means can not in time be made judgement accurately to the reasonable use of storage battery;
Certain customers are difficult to carry out manual inspection owing to use the field condition restriction, and test data analysis needs the O&M personnel to have very high professional level, and it is very high to carry out the risk of battery discharging test;
The current check expense at unattended duty station (institute) is very high, changes for the storage battery that falls behind or lost efficacy, and battery system work is stopped, and causes the risk of power supply infringement;
The discovery of sudden battery failures is difficult to guarantee in time to find, even if find that online in real time is changed immediately; Or the like.This shows, correctly, scientifically use battery, it is very necessary with monitoring management to strengthen regular maintenance, thereby in time finds behindhand battery, for safeguarding and processing provides science, foundation accurately.To this, engineers and technicians have carried out unremitting effort and have proposed many technical schemes.
Analyze and conclude to prior art and scheme, can know that the main monitoring of batteries electric power system and maintenance have following several kinds of modes:
1. adopt the artificial mode that regularly detects, its method is simple, and testing tool and equipment investment are the amount doesn't matter; But workload is big, detects to connect to be prone to loose contact generation error, and efficient is low; Entire system detects weak effect, can not realize real-time processing, is prone to generation systems and loses efficacy.
2. conventional online connects centralized monitoring system, and its mode is that each cell batteries in the batteries that connects to form with the serial or parallel connection mode is connected with the system testing port, takes timesharing control; Connect every group of electric power connecting line of each cell batteries one by one and carry out relevant detection; Every group of electric power connecting line concentrated and is connected system port, makes wiring numerous and mixed and disorderly, is easy to make mistakes; Also waste many wire rods; Particularly can not realize making the cell batteries isolation and carry out independently complete detection, can not accomplish real time fail and handle, detected electrical quantity has bigger limitation.
3. conventional online connects the distributed system mode; Be with the corresponding testing circuit module of each storage battery, and each cell batteries in the batteries that will connect to form with the serial or parallel connection mode links to each other, the holding wire of testing circuit module is connected with system; This mode is compared with centralized system and has been reduced a large amount of electric power connecting lines; Reduced the defective that line waste and line are prone to make mistakes, but the corresponding testing circuit module of each storage battery can increase cost of investment greatly, and; Still can not solve cell batteries is isolated and independent detection, can not accomplish real time fail and handle.
Hence one can see that; Prior art exists many defectives and deficiency, and particularly, the user hopes and can set up real-time and effective " health account " to the cell batteries of battery system; This just need can carry out online monitoring and diagnosis to the cell batteries of battery system; There have been some technical schemes to realize at present to this, but after monitoring and diagnose the storage battery of backward storage battery or fault, also can only have reported to the police; Want manual work to change, exist the hidden danger of huge risk and disaster for online electric power system undoubtedly.Many weeks; The purpose that the user monitors and diagnoses is in order to change storage battery or the storage battery of fault after dropping; Make the batteries electric power system be in good working order all the time, hope can realize the intelligence switching of automatic Hot Spare allotment and trouble accumulator online in real time; All can not realize this prior art and scheme.
