Description
Technical field
The present invention relates to distribution network, specifically electrical power distribution automatization system, the device of more specifically estimating for the power distribution network real-time status based on fuzzy theory.
Background technology
In order to improve the operation and control level of distribution network, we need in a large number network real time data accurately and reliably, but power distribution network remote-measuring equipment is often subject to the interference of random error, instrumental error and mode error and cause these data to have error and unreliability in various degree.In addition,, due to the restriction of measurement equipment quantitatively or in kind, often can not obtain the needed data of complete, enough electric power system computational analysis.
State estimation is to utilize at sequence of threads, processes in real time remote measurement and remote signalling information that telemechanical apparatus is sent here, thereby draws the reliable value of characterization system practical structures and running status, makes the impact of various errors and interference reach minimum.
State estimation algorithm refers under the condition of given network connection, branch road parameter and measurement system, try to achieve the computational methods of optimal State Estimation value according to measuring value, it is the core of state estimation program, and therefore the selection of state estimation algorithm has a significant impact the performance of whole state estimation program.But method for estimating state but needs the device supporting with it to complete.
Summary of the invention
Power distribution network real-time status method of estimation based on fuzzy theory, is to use fuzzy theory to process weight, specifically uses the membership function in fuzzy theory to determine weight.The method, under the condition of given network connection, branch road parameter and measurement system, rapidly, accurately and is all sidedly grasped the real-time running state of power distribution network according to measurement information, for other software provides a complete reliable real-time network database.The method has minimum calculator memory demand and time of implementation, fast, reliable and convergence is good, can process neatly the combination of any type metric data, in the time increasing or remove some and measure, does not need reprogramming.But, better power distribution network real-time status method of estimation all needs to have an operation platform.
The object of this invention is to provide the device that the power distribution network real-time status of a kind of confession based on fuzzy theory estimated.This device is exactly the operation platform of a power distribution network real-time status method of estimation based on fuzzy theory, moves the above-mentioned power distribution network real-time status method of estimation based on fuzzy theory on this device, estimates thereby complete power distribution network real-time status.
The device that power distribution network real-time status method of estimation based on fuzzy theory of the present invention is used, comprise power distribution network data reception module, data processing module, data outputting module and data transmission channel, power distribution network data reception module and data outputting module are all by data transmission channel connection data processing module;

Described data outputting module arranges output interface, for power distribution network real-time status is estimated to output to database.
The data receiver interface of described power distribution network data reception module comprises wired receiving interface and/or wireless receiving interface.
The data output interface of described data outputting module comprises wired output interface and/or wireless output interface.
In described data processing module, two-way concatenation operation district of deposit data district, program storage area concatenation operation district.
In device of the present invention, power distribution network data reception module and data outputting module are all by the deposit data district in data transmission channel connection data processing module.
The present invention is rational in infrastructure, and deposit data district and program storage area separately, are convenient to data call and fast transport, are also convenient to program independent operating, not confusion reigned.Data that receive and need the data of output all to deposit (buffer memory) in deposit data district, even if in the computing in time or can not export in time in the situation that due to fault, can obliterated data yet, do not need double counting.
The present invention finally deposits the data of gained in authentic data storehouse, for other software (as distribution management system, accident analysis software etc.) provides a complete reliable real-time network database.
The calculation procedure of the power distribution network real-time status method of estimation design according to based on fuzzy theory is arranged in the data processing module of apparatus of the present invention, data processing module will move this program, obtains the state estimation value of power distribution network real-time status according to calculation procedure.
