Description
技术领域technical field
本发明涉及电力系统技术领域,尤其涉及一种基于停电数据的台区识别方法及装置。The invention relates to the technical field of electric power systems, in particular to a method and device for station area identification based on power outage data.
背景技术Background technique
在电力系统中台区的线路交织复杂,用户电表呈不规则分布,经常会存在两个或多个台区变压器在一起或附近等的情况,目前对于电能表的台区归属通常是由人工进行记录,而仅靠人工记录智能电表的台区归属,很容易导致制作档案错误,如极易把台区1某些节点(如图中的圆圈所示的节点)制作成台区2的档案,使得台区1、台区2中电能表的户变关系发生异常,造成用电管理人员对用电的管理和计划无法得到准确、合理的实施。In the power system, the lines in the station area are intertwined and complex, and the user's electric meters are irregularly distributed. There are often situations where two or more station area transformers are together or nearby. At present, the station area ownership of the electric energy meter is usually done manually. record, and only relying on manual recording of the station area of the smart meter can easily lead to errors in making files. For example, it is very easy to make some nodes in station area 1 (the nodes shown in the circle in the figure) into the file of station area 2. This makes the household change relationship of the electric energy meters in station area 1 and station area 2 abnormal, and causes the management and planning of electricity consumption by the electricity management personnel to be unable to be accurately and reasonably implemented.
准确建立台区户变关系是确保台区线损计算准确的关键所在,采用台区识别方法,可以识别不同载波网络的工作台区,进而提高户变关系判断的准确性,有利于台区线损的管理。针对台区识别,现有技术中主要采用以下两种方式:Accurately establishing the relationship between households and substations is the key to ensure accurate calculation of line loss in the station area. Using the identification method of the station area, the working station area of different carrier networks can be identified, thereby improving the accuracy of judging the relationship between households and transformers, which is beneficial to the line loss of the station area. loss management. For station area identification, the following two methods are mainly used in the prior art:
第一种是采用先人工分线停电,再逐个线路检查的方式来实现,该类方式费时费力而且会给用户造成不方便。The first is to adopt the method of manual sub-line power failure first, and then check each line one by one, which is time-consuming and labor-intensive and will cause inconvenience to users.
第二种通过安装载波发生器实现台区自动识别,即由电力线每隔预设时间向台区内各个终端设备发送包含终端设备所属的台区编号和相序代号的载波信号,各个电力线载波终端设备根据接收到载波信号确定各个电力线载波终端设备的台区和相序。该类方式实现操作复杂,且必须增设载波发生器,会增加硬件成本,也只能适用于安装了电力线载波终端的台区中。The second is to realize the automatic identification of the station area by installing a carrier wave generator, that is, the power line sends a carrier signal containing the station area number and phase sequence code to which the terminal device belongs to each terminal device in the station area every preset time, and each power line carrier terminal device Determine the station area and phase sequence of each power line carrier terminal device according to the received carrier signal. This type of method is complicated to implement, and a carrier generator must be added, which will increase hardware costs, and can only be applied to stations where power line carrier terminals are installed.
上述台区识别方式不仅实现操作复杂、耗时长,不适用于适应性要求高的场合,且实现成本较高,需要额外增设载波发生器等硬件设备,因此亟需提供一种台区识别方法,以降低台区识别的实现复杂度以及实现成本,同时能够确保识别效率以及识别精度。The above station area identification method is not only complicated and time-consuming to implement, it is not suitable for occasions with high adaptability requirements, and the implementation cost is high, and additional hardware equipment such as carrier generators are required. Therefore, it is urgent to provide a station area identification method. In order to reduce the implementation complexity and implementation cost of station area identification, and at the same time ensure identification efficiency and identification accuracy.

If the power-on time deviation is within the preset range, it is determined that the household transformer relationship abnormal electric energy meter belongs to the corresponding associated station area.
本实施例中,步骤S3后还包括户变关系有效性过滤步骤,步骤包括:若户变关系异常比小于预设阈值,则判定户变校核结果有效,若户变关系异常比率大于预设阈值,则判定出现大量户变关系疑似异常,户变校核结果有疑义,需执行二次校核,重新执行步骤S1、S2以进行二次校核,户变关系异常比率具体可按下式计算得到:In this embodiment, after step S3, a step of filtering the validity of the household-change relationship is also included. The steps include: if the abnormal ratio of the household-change relationship is less than the preset threshold, then it is determined that the household-change check result is valid; if the abnormal ratio of the household-change relationship is greater than the preset Threshold, it is determined that a large number of household-change relationships are suspected to be abnormal, and the household-change check results are suspicious, and a second check is required, and steps S1 and S2 are re-executed for the second check. The specific ratio of household-change relationship abnormalities can be expressed as follows Calculated to get:
户变关系异常比率=户变关系异常数/台区户变校核涉及的用户数 (3)Abnormal rate of household change relationship = abnormal number of household change relationship / number of users involved in household change verification in station area (3)
本实施例通过以台区作为统计维度,对户变关系校核结果进行有效性过滤,在户变校核结果达到一定值时,表明存在大量户变关系疑似异常,再进一步执行二次校核以进一步验证。In this embodiment, by taking the station area as the statistical dimension, the effectiveness of the checking results of the household-change relationship is filtered. When the household-change checking result reaches a certain value, it indicates that there are a large number of suspected abnormalities in the household-change relationship, and then a second check is performed. for further verification.
