Description
Technical field
The invention belongs to field of relay protection in power, particularly a kind of graphical methods of exhibiting of relay protection of power system definite value sensitivity check result.
Background technology
The sensitivity of relaying protection refers to that relaying protection requires the ability that the fault of moving and abnormality can action message to design code.Pass into the ratio of fault amount with device starting definite value or the action definite value of protective relaying device during fault, be called the sensitivity (also claiming sensitivity coefficient) of relaying protection.The amount that protective device increases during fault such as reaction, sensitivity are the ratio of short circuit calculation value and protection setting value; As the amount that reduces when reacting fault, sensitivity then is the ratio of protection setting value with the short circuit calculation value.Sensitivity is the specific targets of examination sensitivity of relay protection, in general projects of relay protection and operating standard, it is had concrete regulation requirement.Relaying protection is sensitiveer, more can react on reliably the fault or the abnormality that require action.
Chinese patent " relay protection on-line check method for electric grid system " (application number: 200810147821.2) proposed by EMS(Energy Management System; EMS) and DTS(DispatcherTraining System; the dispatcher training analogue system) from electrical network, obtains the real-time running data of power equipment parameter, relay protection constant value and electrical network; then carry out calculation of fault according to the protection rules of adjusting, according to checking rule the protection definite value is checked at last.Document " based on the online relay setting check principle of the inverse process of adjusting " (" Automation of Electric Systems " the 12nd phase of the 35th volume) has proposed the online relay setting check thought based on the inverse process of adjusting.Above-mentioned document has all proposed the sensitivity of protection definite value is checked; but present disclosed document does not all relate to the graphical methods of exhibiting of protection definite value sensitivity check result, does not more relate to the methods of exhibiting directly perceived based on the sensitivity check result of geographical wiring diagram.
Based on above analysis, the inventor furthers investigate for the blank of present technical field, and this case produces thus.
Summary of the invention
Purpose of the present invention is to provide a kind of sensitivity check result methods of exhibiting based on geographical wiring diagram, and it can be illustrated in the sensitivity check result of relay protection constant value on-line check system on the geographical wiring diagram intuitively, makes things convenient for the operations staff to check.
In order to reach above-mentioned purpose, the technical solution used in the present invention is:
A kind of sensitivity check result methods of exhibiting based on geographical wiring diagram comprises the steps:
(1) result of calculation is checked in circuit, transformer and the sensitivity of bus protection definite value from relay protection constant value on-line check system acquisition electrical network, comprises the affiliated factory of relaying protection station, computing time, failure mode, protective device, definite value type and sensitivity calculations value and checks result of calculation information;
(2) the factory station on the geographical wiring diagram of search electrical network, to protect the definite value sensitivity data to be associated with corresponding factory station on the geographical wiring diagram of electrical network according to factory's station name, and be provided with mouse and move and eject suspension window data display program, when mouse moves on certain factory's station icon, automatic spring suspension window shows the whole protection definite value sensitivity datas in this factory station, and sorts by sensitivity is ascending;
The protection definite value sensitivity classification of (3) factory being stood is carried out painted, and the rank of different sensitivity is carried out the painted of different colours;
(4) relay protected operation situation that rules the require alarm of listing of adjusting is not satisfied in protection definite value sensitivity; divide the two-stage alarm by sensitivity degree on the low side; near factory's station icon of correspondence, the alarm board is set, when mouse moves to the alarm board, ejects the details that the suspension window shows this alarm.
In the above-mentioned steps (1); during from relay protection constant value on-line check system acquisition sensitivity check result; by corresponding table in the database that directly reads the relay protection constant value on-line check system, or read by the relay protection constant value on-line check system mode that sensitivity check result exports to the file of set form is realized.
In the above-mentioned steps (1), in relay protection constant value on-line check system running, periodically refresh protection definite value sensitivity and check result of calculation, also periodically refresh and be shown on the electrical network geographical wiring diagram.
In the above-mentioned steps (2), when mating according to factory's station name, if the situation that factory bears the same name at the station on same the geographical wiring diagram occurs, search for according to zone name, partition name, factory's station name and factory's station highest voltage level, all mated when upper when these conditions, just think and found target factory station.
In the above-mentioned steps (3), painted to carrying out around the factory station according to the minimum value of all protection definite value sensitivity in the factory station, sensitivity is less, and color is darker.
In the above-mentioned steps (3), painted to carrying out around the factory station by the sensitivity height, employed concrete color is arranged by the operations staff.
In the above-mentioned steps (3), according to the size of sensitivity several intervals are set, each interval corresponding a kind of color.
In the above-mentioned steps (4), to arranging effective time of alarm board, effective time, the alarm board disappeared automatically later, or confirmed to eliminate the alarm board by operations staff's manual operations.
In the above-mentioned steps (4), described alarm board is divided into three kinds of circuit, transformer and buses according to the component type of protection under the definite value.
In the above-mentioned steps (4), the sensitivity threshold value of two-stage alarm is set, more every one-level alarm is arranged the alarm threshold according to the protection definite value of circuit, transformer, bus three types respectively.
After adopting such scheme; the invention has the beneficial effects as follows: on a geographical wiring diagram, can show a large amount of protection definite value sensitivity check result information; show specially (factory's painted, alarm etc. of listing in station) for important information (under-sensitive situation), the information (situation that sensitivity is enough) that is of little use is placed in the corresponding power plant and substation's information.The present invention makes things convenient for the operations staff to understand quickly protection definite value sensitivity check result, and provides the not enough alarm function of sensitivity.The sensitivity of relay protection constant value is significant to power grid operation, and in time showing by color can be greatly intuitively and show efficiently relaying protection real time execution information.
Description of drawings
Fig. 1 is flow chart of the present invention.
Embodiment
Below with reference to accompanying drawing implementation procedure of the present invention is elaborated,
As shown in Figure 1, the invention provides a kind of sensitivity check result methods of exhibiting based on geographical wiring diagram, comprise the steps:
