Description

Technical Field

[0001] The invention relates to the technical field of electric energy metering and collection, and in particular to a method for checking inter-user connections of new users based on the function of an HPLC electric energy meter module. Background Art

[0002] The one-to-one correspondence between the user's electricity meter file in the marketing system and the actual billing electricity meter on site is an important basis for realizing accurate charging of customers' electricity consumption. Once the inter-household is inter-household, it will lead to errors in the customer's electricity charging, seriously affecting the fairness of quantity and fee. However, the inter-household problem caused by the construction specifications of meter installation and meter replacement is common, especially for new users. It is impossible to monitor and judge online based on historical data, and can only be verified through inter-household investigation before the user moves in. At present, there are two common methods for checking inter-household for new users:

[0003] (1) The traditional method of disconnecting and closing the switch under the meter is used to conduct household inspection. One person performs the switch operation in front of the meter box, and another person enters the household to verify whether the household has lost power. This requires two people to perform the operation at the same time, which is inefficient.

[0004] (2) A new user-to-user cross-connection troubleshooting algorithm based on developed equipment; that is, a signal sending and receiving method based on developed hardware equipment to implement new user-to-user cross-connection troubleshooting, which requires equipment cost investment.

[0005] Therefore, it is necessary to study a new method for checking the connection between new users on site to solve the problems existing in the prior art. Summary of the invention

[0006] The purpose of the present invention is to provide a method for checking new user inter-user contact based on the function of an HPLC electric energy meter module, which has high checking efficiency and low implementation cost.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is: a method for checking the inter-user connection of new users based on the function of the HPLC electric energy meter module, including a single-person verification mode and a multi-person parallel verification mode, specifically comprising the following steps:

[0008] Step S1: The master station obtains the list of new areas on the previous day at regular intervals every day. After completing the clock calibration, it sends the collection task of the current exceeding the upper limit event to the collection terminal of the new area. After the sending is successful, the file is pushed to the mobile terminal;

[0009] Step S2: The staff visits households according to the new area files pushed by the master station, connects the portable load on site, records the load switching time in the single-person verification mode, and records the load switching time and load current in the multi-person parallel verification mode, and submits them to the master station for analysis;

[0010] Step S3: According to the load switching time recorded by the mobile terminal, determine whether there is inter-household contact and locate the suspected inter-household contact user.

[0011] Furthermore, in step S3, when a single person conducts a cross-household inspection, if the load switching time reported in the electric energy meter event record and the on-site cross-household record inspection time meet the following requirements, there is no cross-household on-site:

[0012]

[0013] Where, T1 and T2 are the load connection and output time reported by the electric energy meter event, t1 and t2 are the load connection and output time recorded on site, and δ is the time error factor;

[0014] If the reported event record and the on-site record time cannot satisfy the relationship of formula (1), the suspected wrong connection user is selected in the on-site single-person verification mode according to the following relationship:

[0015]

[0016] Where, T1 k , is the load connection and output time reported by the meter k event, t1 and t2 are the load connection and output time recorded on site, T1 k , t1 and t2 are known quantities, and k is an unknown quantity.

[0017] Furthermore, in step S3, when multiple people conduct inter-household verification in parallel, if the load switching time reported in the electric energy meter event record and the on-site inter-household record verification time, and the electric energy meter event reported current and the on-site recorded load current meet the following requirements, there is no inter-household on-site;

[0018]

[0019] Where, I is the load current reported by the energy meter event, i is the load current recorded on site, and ε is the current error factor;

[0020] Since the portable load connected on site may not have current indication, the current recording data is estimated from the rated power:

[0021]

[0022] In the formula, P is the rated power of the connected load equipment, and U is the rated voltage;

[0023] In the multi-person parallel verification mode, suspected wrongly connected users are selected based on the following relationships:

[0024]

[0025] In the formula, I kis the load size reported by the meter k event, i is the load current size recorded on site, T1 k , , t1, t2, i are known quantities, and k is an unknown quantity.

[0026] Compared with the prior art, the present invention has the following beneficial effects: In view of the low efficiency and high investment cost of the existing inter-household investigation methods, the present invention provides a method for investigating inter-household connections of new users based on the function of the HPLC electric energy meter module. The method is based on the event reporting function of the module of the existing HPLC electric energy meter, combined with the characteristics of no users moving in and no electricity consumption in the newly installed area, and realizes the investigation of inter-household connections of new users by comparing the on-site household load switching with the event records reported by the electric energy meter. The method does not require the investment of hardware equipment, only one person is needed to complete the investigation, and it supports multiple people to check in parallel. It has the advantages of high investigation efficiency and low implementation cost, etc., which solves the current problem of low efficiency in investigating inter-household connections of new users, and has strong engineering practicality and broad application prospects.

[0034] Step S3: The master station determines and feeds back the result. According to the load switching time recorded by the mobile terminal, it determines whether there is cross-household connection and locates the suspected cross-household user. The specific implementation method is:

[0035] When a single person conducts a cross-household inspection, taking into account the error of manual operation, when the load switching time reported by the electric energy meter event record and the time of the on-site cross-household record inspection meet the following requirements, there is no cross-household on-site:

[0037] Where T1 and T2 are the load connection and output time reported by the electric energy meter event, t1 and t2 are the load connection and output time recorded on site, and δ is the time error factor.

[0038] If the reported event record and the on-site record time cannot satisfy the relationship of formula (1), the suspected wrong connection user is selected in the on-site single-person verification mode according to the following relationship:

[0039]

[0040] Where, T1 k , is the load connection and output time reported by the meter k event, t1 and t2 are the load connection and output time recorded on site, T1 k , t1 and t2 are known quantities, and k is an unknown quantity.

[0042]

[0043] Where I is the load current reported by the energy meter event, i is the load current recorded on site, and ε is the current error factor.

[0044] Since the portable load connected on site may not have current indication, the current recording data can be estimated from the rated power:

[0045]

[0046] In the formula, P is the rated power of the connected load equipment, U is the rated voltage, and ordinary low-voltage users take 220V.

[0047] In the multi-person parallel verification mode, suspected wrongly connected users are selected based on the following relationships:
