Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Conversely, the present invention covers any replacement done in spirit and scope of the invention being defined by the claims, repaiies
Change, equivalent method and scheme.Further, in order that the public has a better understanding to the present invention, below to of the invention thin
It is detailed to describe some specific detail sections in section description.Part without these details for a person skilled in the art
Description can also completely understand the present invention.
A kind of acquisition abnormity urgency level computational methods based on monthly power consumption, comprise the following steps：
The first step, primarily determines that the factor of influence of acquisition abnormity urgency
The factor of influence of acquisition abnormity urgency is determined by electric power operational system expert discussion, the factor of influence includes the moon
Equal power consumption.
Second step, the data of collecting circuit runtime
The data include collection in worksite data and trouble ticket dispatch data, are related to one section of the various users in multiple regions
Power consumption in time, and then power consumption to high-volume user carries out fluction analysis.
3rd step, sets up standard electricity consumer
For accurate evaluation factor of influence, it is necessary to set standard electricity consumer.Standard electricity consumer is to extract most of user
The monthly average power consumption of all types of user is counted on the basis of actual electricity consumption situation, is then put down according to the electricity consumer of the most types of user
Used as standard electricity consumer power consumption, finally all conversion is standard electricity consumer to equal electricity for influence of all factors of influence to urgency.
The abnormal urgency level of current system judges that relying primarily on the experience of people and subjectivity estimates to carry out distribute leaflets treatment, this
There is very big not scientific and randomness in the method for kind.In order that the judgement for obtaining abnormal urgency can be more scientific and can be measured,
Present invention introduces standard electricity consumer concept, finally all conversion is standard electricity consumer to the influence by all factors of influence to urgency.
And during actual O＆M, on the one hand abnormal urgency factor of influence is more and belongs to different type, on the other hand complete
There is the Different Effects factor each place in the range of state, and various factors there is also difference to final urgency influence size, it is difficult to be
System grasps all factors of influence comprehensively at the very start, there is addition, the possibility deleted and change.Therefore, using standard electricity consumer
Concept, finally all conversion is standard electricity consumer to the influence by all factors of influence to urgency.Standard electricity consumer is to extract greatly
The monthly average power consumption of all types of user is counted on the basis of the actual electricity consumption situation of certain customers, then according to the most types of user
Electricity consumer average electricity as standard electricity consumer power consumption.
4th step, the analyzing influence factor simultaneously sets up model
As shown in figure 1, on the one hand due in the whole country each region acquisition system specific requirement is had differences, in addition one
Aspect acquisition abnormity urgency factor of influence is a lot, thus each region need according to its actual conditions judge each influence because
Whether son should count urgency calculating.Urgency factor of influence judgment models are exactly to have service data by system, according to
Each factor influence carries out data analysis, when result shows that factor of influence has obvious paradigmatic relation or continuous with final result
Shi Ze shows that the factor is counted into urgency calculates, and then showing when result is discrete discontinuous should not be by the factor meter
Enter urgency calculating.
Set up the computation model of monthly power consumption, monthly power consumption to the impact analysis method of acquisition abnormity urgency level,
Observation is when user's electricity is lacked, if platform area line loss can be caused to fluctuate, if causing fluctuation, needs to make monthly power consumption
To influence the factor of influence of urgency, if do not fluctuated, need not.
Analyze influence degree of the monthly power consumption to acquisition abnormity urgency level, directly with user the moon power consumption as defeated
Enter, the influence fluctuation of the factor can be caused excessive, it is therefore desirable to user month power consumption is divided by certain interval.By platform area
Classified according to capacity, and counted that a certain annual platform area is public to become power consumption and respective volume is public becomes lower resident, non-resident
(single-phase, three-phase) charge condition.
Specific statistical analysis process is as described below, and the Ge Tai areas of a certain region 242402 are classified according to capacity,
And count the public change power consumption in a certain annual platform area and the public change of respective volume lower resident, non-resident (single-phase, three-phase) charge condition.
As Figure 2-3, with 250 kilovolt-amperes and following resident's electricity is 100 kilowatt hours or so, 315 kilovolt-amperes and
More than single-phase user be its 2 times or so, 250 kilovolt-amperes and following non-resident three-phase meter be its 3 times or so, 315 kilovolt-amperes and with
Upper non-resident three-phase meter is its 10 times or so.
If using only electricity as emergency value unit, the numeric ratio for finally calculating is larger, it is necessary to converted,
Determine that the user is in the specific distributed area of statistics according to the actual moon power consumption of user, finally determine that the user is N number of
Standard electricity consumer.
From Fig. 4-5, when single-phase user's electricity is lacked, the line loss fluctuation of platform area will be caused in 0.6%-0.7%,
When one it is non-occupy three-phase user electricity and lack when, the fluctuation of platform area line loss will be caused 3.5% or so.Therefore, monthly power consumption energy
Enough factors of influence as influence urgency.
With resident and non-resident single-phase meter user month power consumption (200,000 are less than or equal to as standard family electricity separation
Watt-hour) it is 1 family standard family, (more than 200 kilowatt hours and less than or equal to 1000 kilowatt hours) are 2 family standard families, (are more than 1000 kilowatts
When) it is 3 family standard families.
The equivalent standard amount r (x of the actual moon power consumption of useri)：
g(xi) it is the power consumption for specifying user's current moon, XiIt is i-th user of electric energy meter
Factor of influence also includes：Abnormal lasting, distance are checked meter number of days, electric energy meter value of utility, intermittent defect.
Set up the computation model of aberrant continuation number of days
Each household is analyzed per daily power consumption standard deviation degree, whether the daily power consumption fluctuation for analyzing user is gentle, such as
The gentle electricity that can be then lost aberrant continuation number of days of daily power consumption fluctuation of the most of user of fruit is calculated as urgency level
The factor, the electricity that can not be lost aberrant continuation number of days if the daily power consumption fluctuation of most of user is larger is used as urgent
Degree calculates the factor.
Certain January 10000 family resident and non-resident daily power consumption data are collected, are calculated per daily power consumption standard deviation,
And arrange from small to large, show that curve map is as shown in Figure 6.Determine that number of users of its electric standard deviation less than 17 accounts for sum
92%, it is the flex point of standard deviation curves figure.
Likewise, it is non-resident to select 10000 families immediately in a certain region, calculate per daily power consumption standard deviation, and from small
To longer spread, show that curve map is as shown in Figure 7.Determine that number of users of its electric standard deviation less than 17 accounts for sum
88.75%, it is the flex point of standard deviation curves figure.
From Fig. 6 and Fig. 7, assert that 90% or so the average daily electricity fluctuation of user is small, therefore, aberrant continuation number of days can
As the factor of influence of influence urgency.
The odd-numbered day loss monitoring electricity that the present invention is caused using the per day electricity within month as failure number of days.It is abnormal
The electricity that continuous dayses are lost=aberrant continuation number of days is multiplied by the average daily power consumption of the specified user current moon, specifies user to work as
The power consumption of the preceding moon needs to refer to user's upper one year with month power consumption, a upper month power consumption and first three daily power consumption.
Computing formula is as follows：
More accurately to estimate the moon power consumption of specified user, increase the lunar calendar Gregorian calendar, temperature humidity over the years influence, this use
Family year increases by the factor to affect of power consumption etc. on a year-on-year basis.
The emergency value formula of Abnormal lasting is as follows：
Distance is set up to check meter the computation model of day number of days
The meter reading data of example of checking meter day is mostly important in the middle of one month, and shortage of data will cause manual metering within this day, make
Cost is obtained to improve.Nearer apart from next day of checking meter, abnormality processing urgency is higher.Accordingly, it would be desirable to check meter day number of days of distance is made
To influence the factor of influence of urgency.
Statistics continues the relation of the N days electric energy meter number distribution situations without meter reading data, analysis failure ammeter and continuous dayses,
It is determined to process the number of days M of most failure ammeters.Data are counted using section statistical, counts a certain section
Still unrecovered abnormal electric energy meter in time, record continues the N days electric energy meter number distribution situations without meter reading data.
It can be seen that the failure ammeter user for continuing 2 days to 8 days accounts for the 59.06% of total failare number of users from Fig. 8-9, will
Nearly 60%, continue 9 days to the 21 days users without recording electric energy meter data and account for the 30.72% of total failare number of users, nearly 30%, continue
22 days and above accounting 10.22%, nearly 10%.
Find out from analyze data, nearly 60% acquisition abnormity can all be processed within 8 day time, so selection 8 is heaven-made
It is threshold value, the factor influence that threshold values is exceeded apart from number of days is 0, apart from number of days, smaller treatment emergency value is bigger in threshold values.
Distance day number of days abnormality processing urgency computation model of checking meter is as follows：
Set up the computation model of intermittent defect
Specific aim analysis is carried out by operational system data, when result shows that factor of influence has substantially pass with final result
Then show that the factor is counted into urgency calculates, and should then show when result is discrete discontinuous when system or continuous
The factor is counted urgency and calculated by this.
Producer according to concentrator type, region, concentrator carries out statistics failure electric energy meter quantity, electric energy meter number respectively
Amount.Calculate same concentrator type, the electrical energy meter fault rate of different geographical.Calculate same concentrator type, different manufacturers
Electrical energy meter fault rate.Analyze whether various electrical energy meter fault rates have discrete feature, if various electrical energy meter fault rates have
Discrete type, the factor of influence that the factor is exported not as emergency value, conversely, the influence that exports as emergency value of the factor because
Son.
Found in the seminar of optimization collection O＆M closed loop management system and basic unit's investigation process, presently, there are meter reading data
The intermittent phenomena for cutting in and out, i.e., failure is gathered for single meter but the phenomenon that can voluntarily recover without manpower intervention compared with
For obvious.Quantitative analysis is carried out to meter reading data situation：1 representative is checked meter successfully, and 0 representative is checked meter unsuccessfully, the group of its meter reading data
Be combined into 101 ..., 1001 ..., 10001 ....Phenomenon occurs repeatedly in such failed subs criber in one month be 101 ...,
1001 ..., 10001 ..., 100001 ... combined situation.
Certain January is collected, certain region 24907294 family low-voltage customer whole month meter reading data is analysis sample, i.e., one month
Inside at least occur three times and the above 101 ..., the user of 1001 ..., 10001 ..., 100001 ... combined situations are according to collection
Middle device type, region are counted.
As shown in figs. 10-11, calculating analysis is carried out to data：There is the meter collection event of intermittent defect in I type concentrators
Barrier rate average value is 5.49%, and the standard deviation value of the dispersion degree in sign group between individuality is 0.0107.
Likewise, the single meter under the II type concentrators of the intermittent defect occurred for certain January gathers fault rate
Counted by region,
As illustrated by figs. 12-13, data are carried out calculating analysis analysis：The meter that intermittent defect occur in II type concentrators is adopted
Collection fault rate average value is 2.73%, and the standard deviation value of the dispersion degree in sign group between individuality is 0.0071.
Understood according to Figure 10-13, it is necessary to reference station area lines branch quantity, extend when analyzing different types of concentrator
Region area, live power utilization environment and line style.I type concentrators occur intermittent defect meter gather fault rate apparently higher than
II type concentrators, main cause is many, wide, live power utilization environment complexity in extension region of low-voltage platform area lines branch etc., is caused low
Piezoelectricity powerline carrier communication is unstable, and II type concentrator downlink communications are mainly RS485 twisted-pair communications, therefore more steady
It is fixed, but for same type concentrator, intermittent defect occurrence rate is relatively stable.
There is the user's inventory under 3 times, 5 times, the 6 times and 7 times I type concentrators of intermittent defect continuing with one month to press
Electric energy meter producer is counted, it is found that failure focuses primarily upon Shenzhen Spacefight Techrise Electronics Co., Ltd, Shenzhen section land, Hangzhoupro
State Haixing County, the western power in Hangzhou, Zhejiang Maxwell, but this five installation numbers of electric energy meter producer are also very big, further calculate this five
Individual electric energy meter producer breaks down ratio, substantially 0.227% or so, as shown in figure 14.
Similarly, we have been also carried out statistics to terminal producer, it is found that failure focuses primarily upon Jiangsu light one, Hangzhou torch China Tech
Skill, Skyworth, Jiangsu Linyang Electronics Co., Ltd., Qingdao GaoKe Communications Technology Co., Ltd., equally, this five terminal producers
Installation number it is also very big, further calculate the ratio that breaks down of this five terminal producers, substantially 0.247% or so,
As shown in figure 15.
For the user's inventory under 4 times, 5 times, the 6 times and 7 times II type concentrators of intermittent defect of an appearance in month by electricity
Can table counted, find failure focus primarily upon electric energy meter producer for Hangzhou Haixing County, De Lixi, the positive Thailand in Zhejiang, the western power in Hangzhou,
Zhejiang Maxwell, but this five installation numbers of electric energy meter producer are also very big, further calculate this five electric energy meter producers and occur
Failure ratio, substantially 0.061% or so, as shown in figure 16.
Similarly, we have been also carried out statistics to terminal producer, find failure focus primarily upon eight reach, Jiangsu Lin Yang electronics shares
Part Co., Ltd, Hangzhou torch China Tech skill, Hangzhou torch China Tech, the skill of Jiangsu light one, equally, this five installation numbers of terminal producer
It is very big, further calculate this five terminal producers and break down ratio, substantially 0.055% or so, as shown in figure 17.
It is seen from the above data that intermittent defect is not presented aggregation effect (as by meter producer, terminal factory
Family, Distribution Area, concentrator type etc.), in the presence of certain discrete feature.
Continue type (101 ..., 1001 ..., 10001 ..., the 100001 ...) quantity and ratio to there is each failure
Example is counted.As depicted in figures 18-20, either I types concentrator or II type concentrators, occur 3 times within one month and the above between
The concentrator fault type of having a rest property failure is concentrated mainly in 101,1001 both types, the automatic intermittence recovered in three days
Failure accounts for more than the 90% of intermittent defect total quantity.
Intermittent defect is not presented aggregation effect (such as meter producer, terminal producer, terminal type, Area distribution
Deng), there is the automatic intermittent defect accounting more than 90% recovered in certain discrete feature, and three days, therefore collection O＆M
Troubleshooting time limit in closed loop management can not characterization failure treatment complexity, therefore the factor is defeated not as emergency value
The factor of influence for going out.
Set up under terminal and mount the computation model of electric energy meter value of utility
The number of faults and handling duration system of the whole acquisition abnormities influence produced on certain time period in current acquisition system
Meter analysis.
As shown in fig. 21-22, there is problem one：The electric energy meter number of one fault type influence is more, then processing priority
Higher, the sequence of troubleshooting benefit should be：Completely without data under I type concentrators>I types terminal is with main website without communication>II types are concentrated
Device is completely without data>II types terminal is with main website without communication>Ammeter is completely without data under collector>N days without recording electric energy meter data, according to place
Reason urgency level is successively decreased arrangement, and the process limited should be incremented by principle, but in I types concentrator and main website without communicating and N days no datas
Two classes occur in that the average treatment time limit declines obvious trend extremely, illustrate there is problem.
There is problem two：Ammeter distribution proportion is mounted under II type collectors under electric energy meter
As shown in figs. 23-24, it can be seen that the situation of II type collector 1 piece of electric energy meter of carry account for 94.91%.According to
Data result is investigated and analysed, due to grass-roots unit and do not know about the type calculating be mounting 2 pieces of electric energy meters and the above
II type collector exceptions, blindness thinks that the II types collector mounting electric energy meter overwhelming majority is 1 piece of electric energy meter, causes maintenance positive
Property is not high.Value of utility is exported in O＆M to be needed to consider carry failure electric energy meter number, and not exclusively mounts electric energy meter under terminal
Number, can not otherwise reach the maximization of O＆M effectiveness.
To sum up analysis is, it is necessary to using electric energy meter quantitative utility value as the factor of influence of influence urgency is mounted under terminal, be
System can judge its priority, overall utility value mould by analyzing each treatment lower value of utility summation of faulty ammeter of work order
Type is as follows：
Y (emergency value)=∑ f (xi) (i represents the 1st after collecting ... the electric energy meter of n)
xiIt is i-th user of electric energy meter, f (xi) represent i-th electric energy meter user urgency
Set up total acquisition abnormity urgency level computation model
By the acquisition abnormity urgency level influencing factors analysis to existing collection, come for single meter emergency value
Say mainly there is " distance check meter number of days ", " Abnormal lasting " and " monthly average power consumption ", " electric energy meter value of utility " four directions at present
Face rings, and " intermittent defect " does not occur direct relation, therefore the factor does not consider.The emergency value of abnormal work order is the work order
Comprising failure ammeter emergency value it is cumulative.Total acquisition abnormity urgency level computation model is：
Y (emergency value)=∑ f (xi) (i represents the 1st after collecting ... the electric energy meter of n)
f(xi)=j (xi)+s(xi), wherein：
Thus total emergency value of single table is obtained, the precedence for instructing abnormality processing enables to daily collection
Maintenance work is shot the arrow at the target, and reaches the effect got twice the result with half the effort.
5th step, according to computation model, determines the precedence of abnormality processing, and circuit runtime is safeguarded.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
