Description

A kind of one-end substation bus Rapid self-healing device
Technical field
The utility model is related to a kind of one-end substation bus Rapid self-healing device, belongs to Automatization Technology in Transformer Substation Field.
Background technology
With the development of the social economy, requirement more and more higher of the people to power supply reliability.Alternate power autocast is filled Put be after main power supply has a power failure because in itself occurring accident for line fault or power supply, can be rapidly automatically by in-put of spare power supply Work, makes working power user after being disconnected be unlikely to a kind of automatics having a power failure, is widely used in 220kV and following In voltage class system.Domestic application it is more be that single automatic throw-in equipment of emergency power supply is set, mainly realize inlet wire, master Transformer, the standby input function of segmentation.For the different development characteristic of domestic power network, electric power enterprise, the collection such as colleges and universities, designing unit In throw, carried out research with small be electrically accessed in terms of standby throwing, standby input of acting in collusion to make each other's confessions many electric power incoming lines are standby.But for being typically single The 220kV one-end substations that line or double loop are powered, once power supply disappears, it will and whole station dead electricity is caused, how to be replied immediately soon Electricity, it is ensured that the research of dead electricity aspect is not less for responsible consumer.
The automatic spare device input strategy of traditional automatic throw-in equipment of emergency power supply is in 220kV one-end substations important negative There is problems with the application of lotus bus:
1st, 220kV one-end substations are because of 220kV power supply only one of which, it is impossible to use automatic throw-in equipment of emergency power supply, and Automatic throw-in equipment of emergency power supply loaded on 110kV sides, the dead electricity caused that disappeared to power supply is also helpless;
2nd, the automatic spare device input strategy of traditional automatic throw-in equipment of emergency power supply only accounts for local substation bus bar Voltage or line current, capacity-load ratio, the thermally-stabilised limit of circuit without considering standby electricity source etc., if load shifts it Standby electricity source overloads afterwards, it is likely that further result in failure propagation;
3rd, traditional automatic throw-in equipment of emergency power supply is essentially all the standby input of several fixations of each factory settings Mode, when transforming plant primary changes of operating modes or complicated various power network wiring form, producer is difficult to the various methods of operation Consider comprehensive, conflict once the live Main connection form of appearance and the method for operation have with design logic, alternate power autocast dress Putting to use.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of one-end substation bus Rapid self-healing device, is not changing Completed on the basis of the existing system architecture of transformer terminals transformer station and one or two times overall wirings important load bus it is quick from More function, so as to avoid the risk of 220kV one-end substation whole station dead electricity.
The technical solution of the utility model is:At least include power insert, CPU plug-in units, exchange input plug-in unit, A/D samplings Plug-in unit, open into plug-in unit, output plug-in unit, man-machine plug-in unit.Wherein, processor CPU plug-in units and other plug-in units are carried out by internal bus Data exchange, power insert is that device and other plug-in units provide working power, and A/D sampling plug-ins input the exchange of plug-in unit to exchange Amount sampling by being sent to CPU card on internal bus, is opened after plug-in unit collection intake signal by being sent on internal bus simultaneously To CPU card, output plug-in unit and the order of CPU card is received to relative breaker progress division operation by internal bus;
It is that device and other plug-in units provide working power that power insert, which is used for,;
CPU plug-in units are the core components of the present apparatus, mainly complete following function:The sampling of analog input, calculate and patrol Collect arbitration functions, liquid crystal display and indicator lamp and indicate that function, logout and failure wave-recording function, device start and break function And communication management function.In addition processor module(CPU plug-in units)Also with a high-precision clock, height is provided for device The real-time time of precision, at the same can handle various ways pair when signal input;
Exchange input plug-in unit is an analog quantity modular converter, with two groups of control sources, one group of electric current input.Can be High level analog quantity is converted to the lower valued analog amount that the sampling of the suitable present apparatus is used, while realizing electric power primary system and the present apparatus It is effectively isolated.The module also carries passive low-pass filter circuit, for filtering out the interference signal in every road analog input channel;
A/D sampling plug-ins use the high-precision A/D sampling A/D chips of 16, and the of ac for being mainly used in exchange input plug-in unit is adopted Sample, while sampled data by being sent to CPU card on internal bus;
It is a switching value acquisition module to open into plug-in unit;
It is a tripping operation contact output module to output plug-in unit;
Man-machine plug-in unit mainly includes keyboard, liquid crystal display and signal lamp, needed for for setting bus self-healing function Relevant parameter and definite value, observation real time data and unit state etc. and query history report.
Principle of the present utility model is:The relevant parameter and definite value of bus rapidly self-healing logic are set by man-machine plug-in unit, Then CPU card is according to selected logic, by the analog quantity to in-site collecting, on the spot switching value and by IEC61850 or The voltage and on off state of other measure and control device collections carry out logical operation and judgement in IEC60870-5-103 agreement acquisition station, Logically computing and the result that judges are by outputing the division of relative breaker in plug-in unit control station, so that terminal power transformation Stand the important load bus energy rapidly self-healing in inlet wire failure and main transformer failure.
The alternate power autocast that the present apparatus is applied to the main electrical scheme transformer stations such as interior bridge, single busbar, sectionalized single busbar connection is patrolled Collect fast quick-recovery logic function after function and no-voltage of entire station.
The beneficial effects of the utility model are:The existing system architecture of transformer station and overall one or two times can not changed On the basis of wiring, by existing interior communication network in transformer station and the measure and control device at each interval, important load bus is realized Rapidly self-healing function, while the correlation of bus rapidly self-healing logic can be set according to the actual load situation of transformer station's load side Parameter and definite value, meet the demand of the different bus rapidly self-healing in scene.
