Description
Technical field
The utility model relates generally to Electric Energy Metering Technology field, refers in particular to a kind of electric energy meter system based on bimodulus communication.
Background technique
Power supply reliability can reflect network system continued power ability, and the important finger of examination power supply system power supply quality
Mark has reacted power industry to the satisfaction degree of national economy electrical energy demands, has had become and measure a national economy prosperity journey
One of standard of degree；Power supply reliability can be measured with a series of following indexs: when power supply reliability, user averagely have a power failure
Between, average frequency of power cut of user, user's mean failure rate frequency of power cut；General urban area reaches China's power supply reliability at present
3 9(i.e. 99.9%) more than, user's annual power off time 10.5 hours, meanwhile, grid company to power supply reliability index propose
It requires:
(1) urban electricity supply reliability is not less than 99.89%, and rural power service reliability is not less than 99%；
(2) it reduces because what power supply unit scheduled overhaul and power system accident had a power failure to the frequency of power cut of client and every time holds
The continuous time.When power supply unit scheduled overhaul, to the frequency of power cut for the client that 35 kilovolts and above are powered, do not answer every year
More than 1 time；To the client of 10 kilovoltage grades power supply, it is not to be exceeded every year 3 times；
(3) when power supply facilities needs to have a power failure because of scheduled overhaul, Ying Tiqian 7 days is by power supply interrupted district, route, power off time and extensive
The time powered again is announced, and notifies Very Important Person.Power supply facilities is because ad hoc inspection and repair needs to have a power failure, and Ying Tiqian 24 hours
Notice responsible consumer is announced；
(4) it to power failure in emergency circumstances or rations the power supply, when customer inquiries, explanation work should be carried out to client, and extensive as early as possible
Multiple normal power supply.
Currently, national grid sales department has issued, " Guo Wang sales department is about development acquisition terminal and electric energy meter power-off event
The notice of data preparation work ", grid company has been realized in above-mentioned requirements, but has also paid very big financial resources and object thus
Power.In order to fundamentally solve the problems, such as this, therefore it is required that smart machine technically finds the power-off event of user as early as possible, especially
It is the power-off event of ordinarily resident user into current demand.
The terminal to put into operation completes upgrade job by " acquisition terminal and electric energy meter power-off event data preparation rule ", simultaneously
Site intelligent electric energy meter also all supports acquisition, storage, analytic function of the terminal to electric energy meter logout, electricity consumption to acquire information system
System can be achieved to the stopping of intelligent electric energy meter, power on logout acquisition.But it can not accomplish in intelligent electric energy meter power-off event active
Report will greatly promote the timeliness of residential electricity consumption maintenance, and promote electricity consumption if realizing the real-time active reporting technology of low-voltage customer power failure
User satisfaction.
If you need to realize to the transformation and upgrade (changing table) in terms of original intelligent electric meter progress software and hardware, therefore the function needs
The problem of can not be achieved intelligent electric meter power-off event active reporting function by existing intelligent electric meter.How intelligence be not transformed
Under the premise of electric energy meter, a kind of novel real-time active reporting technical solution of electric energy meter power-off event is studied, the task of top priority is become.
Therefore, how modern science and technology such as computer technology, wireless long haul communication technology to be combined with solve traditional electrical energy measurement and
The defect of existing automatic electric energy meter reading technique, is the inexorable trend of the development of current intelligent electric energy meter, and realization makes user
With accurate, the real-time detection of electric energy and power-off event active reporting.
Its safety at power cut analyze below with reference to several scenes and determines main cause:
(1) low-voltage customer power failure scene analysis
Resident's power failure has a power failure before being divided into table and has a power failure after table, has a power failure after table and is not responsible for by Utilities Electric Co., therefore is having a power failure
Before information reporting, need to power-off condition distinguishes differentiation and selectively reports in turn before table, after table.8 kinds to have a power failure before table
Failure cause can induction and conclusion be 4 kinds of power failure scenes: full court area have a power failure, certain mutually has a power failure, certain building (unit) have a power failure and certain list
(number) family has a power failure.At present only occur full court area power outage when, terminal can in time, active reporting to main website, other situations
It can not in time, accurately report.
(2) low-voltage customer power-off event report flow
Under normal power-off condition, the meter function as provisioned in platform area is different, low-voltage customer power-off event report flow
Following two situation can be divided into:
The first situation: when power-off event occurs, ammeter can report outage information to concentrator in time, and concentrator receives electricity
Main website can be reported to after table outage information, main website is in conjunction with system file database and GIS information, promptly and accurately positioning failure class
Type and abort situation, notification technique attendant go to debugging.
Second situation: occur power-off event when, concentrator automatically detect platform area have a power failure and phase line outage information after and
When be reported to main website, main website is in conjunction with system file database and GIS information, promptly and accurately positioning failure type and fault bit
It sets, notification technique attendant goes to debugging.
Power-off event is unable to after the one of the major reasons of active reporting are line outage at present, and the battery in ammeter is only capable of
Electric energy meter is supported to generate power-off event and be but unable to maintain that reporting for power supply event.A large amount of power-off events do not report several in time
Reason:
(1) outage information studies and judges mechanism and reports rule design unreasonable, and brownout information is caused not to be recorded or do not have
Have and is reported in time；
(2) in outage information transmission process, lack the labeling process to power off time, power-off event is caused not sentence accurately
Disconnected power off time, and then cause customer interrupted that cannot be handled in time；
(3) after having a power failure, ammeter backup circuit, powering, it is too short to hold time, and can not be transmitted in time outage information
Concentrator, main website.
