The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1
Referring to fig. 1 to 3, an embodiment of the present invention provides a distributed feeder automation evaluation method for 5G wireless communication, including:
s1: dividing each section of the power distribution network according to the standard of whether the power distribution network has electricity or not;
it should be noted that, the power distribution network segment division includes,
when the power distribution network operates normally, defining an electrified section as a normal section and defining a non-electrified section as a power failure section;
when the distribution network fails, a section which is powered off due to the failure is defined as a failure section, and a non-failure section which is powered off due to reasons except the failure is defined as a section to be recovered.
Specifically, according to the state change rule of the power supply section before and after the occurrence of the fault and the processing of the fault, the state of the section can be divided into a normal state, a fault state, a to-be-recovered state and a power failure state; when the power distribution network normally operates, initializing all the sections with points to be normal, and initializing the sections without power supply to be power failure; after a fault occurs, a non-fault area with power failure caused by tripping of the outlet breaker is in a state of waiting to be recovered, and a fault section is in a state of fault.
S2: judging the rationality of the change of the switch state of each section of the power distribution network in the feeder automation processing process based on the division result;
it should be noted that, the judgment of the rationality of the switch state change includes,
when a normal section before feeder automation processing is changed into a power failure section or a fault section or a section to be recovered in the feeder automation processing process after a power distribution network fails, judging that the normal section is unreasonable, otherwise, judging that the normal section is reasonable;
when a fault section before feeder automation processing becomes a normal section or a section to be restored in the feeder automation processing process after the distribution network has a fault, judging that the fault section is unreasonable, otherwise, judging that the fault section is reasonable;
and when the power failure section before the feeder automation processing is changed into a normal section or a fault section or a section to be restored in the feeder automation processing process after the power distribution network fails, judging that the power failure section is unreasonable, otherwise, judging that the power failure section is reasonable.
Specifically, the change of the state of each section can be obtained by performing continuous network topology analysis on the switch position change caused by operating the switch in the fault processing, and the safety of each operation process of the fault processing system can be analyzed from the process of the state change to be used as a criterion for judging whether the fault processing system fails or not.
Table 1 shows the rationality of causing a zone state transition before and after a switching operation during fault handling; "x" indicates that this operation is not reasonable, which may cause the system to enlarge the fault range or cause a safety accident; "√" indicates that the operating procedure is non-destructive; "-" indicates that the operation did not result in a change in the state of the segment.
Table 1: and a rationality table for causing a zone state transition before and after a switching operation during a fault handling process.
More specifically, if a section is changed from "normal" to any other state, it indicates that the normal charged area is lost due to the fault handling operation, which is a typical case of the expansion of the fault range; so this transition is judged as "x"; the section where the fault is located cannot recover power supply before the fault is eliminated, and the section cannot be converted into a normal state and a to-be-recovered state, so that if the conversion occurs, the section is also an error transition and is judged to be X; a section whose status is "to be restored" can be converted into any section because it has been powered off for a failure reason; if a sector changes from "power off" to any other state, it is also judged as "x". The reason is that the section with the state of power failure before the fault is isolated from the distribution network for maintenance or other reasons by a dispatcher, so that the section is in an island state, and because the fault processing causes the section to be connected with other sections, the sections can be electrified again, and personal safety or equipment safety problems can be caused.
The fault processing operation result can be finally embodied by using a fault processing process coefficient K, and if any section has no error state transition in the primary fault processing process, the value of K is 1; otherwise, the value is-1.
S3: calculating the fault processing load recovery rate of the power distribution network in unit time by using a hierarchical analysis strategy;
wherein the defined unit time includes a certain unit time within 3 minutes or 3 minutes.
It should be noted that, the formula for calculating the fault handling load recovery rate of the power distribution network per unit time includes,
fsh＝Psh/Pnm*100％
wherein, PshRepresenting the power supply load per unit time, P, of the power supply being restored during the automatic processing of the feedernmRepresenting the power supply load per unit time before the failure of the distribution network.
Specifically, since the size and speed of the final restoration section of the fault handling system are closely related, the index not only accommodates the fault handling speed and the power supply fault handling rate, but also includes an economical-related index such as the section load amount in the distribution line; meanwhile, the reliability of the primary power distribution network is reflected to a certain degree.
Obviously, the failure processing load recovery rate FshThe larger the time is, the lower the comparability of the index is; considering that the operation time of most failure processing modes is within 3 minutes, a failure processing load recovery rate of 3 minutes can be taken.
S4: and comprehensively evaluating the automation processing effect of the feeder according to the rationality judgment result and the fault processing load recovery rate, and finishing the automation evaluation of the distributed feeder.
It should be noted that the reliability evaluation indexes of the feeder automation process include,
Fsh＝K×fsh
wherein K represents a fault handling process coefficient reflecting the rationality of the fault handling process, Fsh< 0 indicates that there is an irrationality in the feeder automation process, Fsh>0 denotes reasonable automatic processing of the feeder, FshThe larger the reliability of the feeder automation process.
Furthermore, the value standard of the fault handling process coefficient K includes,
and when all sections meet the rationality in the automatic feeder processing process, the value of K is 1, otherwise, the value of K is-1.
Specifically, the above formula gives a quantitative index of reliability of single fault handling in combination with a fault handling process coefficient K reflecting the rationality of the fault handling process.
Furthermore, the reliability evaluation index of the feeder automation process further includes,
Fsh＝K×(fsh+0.1)-|K|×0.1
in the above formula, (0.1) is the significance of the technical processing that when the load recovery rate of the shielding failure processing is 0, the error in the failure processing process is covered, the accuracy of the evaluation result is improved, and FshLess than 0 indicates that the fault handling operation process is unreasonable; fshThe greater the value is, the better the reliability of feeder automation processing is.
In order to verify the technical effects adopted in the method, the embodiment adopts the traditional technical scheme to perform comparison test with the method of the invention, and compares the calculation results by means of scientific demonstration to verify the real effect of the method.
The traditional technical scheme is as follows: two methods are generally adopted for evaluating the action result of FA: (1) checking whether the final result is consistent with the set result; (2) it is checked whether the course of action is consistent with the set course. These methods can reflect the reliability of various feeder automation systems to some extent, but have the following disadvantages: the operation of fault processing has strict time sequence, for example, before the fault area is not isolated, the recovery operation of the non-fault area can not be carried out, otherwise, the fault range is expanded, and the power supply safety of a normal line is caused, so that even if the action result state is correct, the safety in the action process can not be ensured; only qualitative judgment can be carried out, and indexes such as recovery proportion, recovery speed and the like of a non-fault area cannot be judged by a feeder line automation system; when the input conditions are not met or the information is not met, the final result is often different from the set result, but the help provided by different processing schemes for the final client is different, which cannot be reflected; a fault processing result related to not only the size of the restoration of the power supply area but also the speed of the restoration; during fault handling, possible misbehavior can lead to live service sections or to an enlarged fault range.
According to the invention, the FA processing effect is evaluated from two angles of an FA action process and an FA action result, and through the evaluation methods, whether different feeder automation methods have the capability of correctly processing the fault under the condition of an active power distribution network can be verified, and a method for judging the fault processing recovery effect under the condition of the active power distribution network by different feeder automation methods is established.
As shown in fig. 2 to 3, if a fault occurs at the outlet breaker S1 and the power supply, S1 disconnects all the downstream switches K1 and K2 from power loss to become a region to be restored, and after evaluation by the method provided by the present disclosure, only one of the adjacent interconnection switches K9, K10 and K12 is closed; selecting K9 as a closed switch, supplying power to the S1 feeder line power supply downstream area by the S2 feeder line, and evaluating to obtain that the power supply capacity of the S2 feeder line can not meet the requirement of the load at the moment, then K9 firstly judges whether the load between the downstream switch K2 and the downstream switch can be smaller than the residual power supply capacity of the switch, and continues to be continued by a downstream switch K1 and a K9 switch is closed to be a section switch, the K2 is regarded as a new tie switch, and the like, at the moment, K9 is disconnected to be a new tie switch, and the residual tie switches K10 and K12 continue to perform fault recovery calculation according to the algorithm of the text, so that a new fault recovery scheme is obtained, and is shown in the following table.
Table 1: a new failure recovery scheme.
