Description
Technical Field
The invention relates to the field of power system fault diagnosis, in particular to a method for diagnosing power failure of a low-voltage user by utilizing telecommunication terminal equipment.
Background
At present, the diagnosis and alarm technology aiming at the power failure fault of a main network and a power distribution network is quite mature, and the effective diagnosis technology aiming at the power failure of a single or a plurality of low-voltage users under a low-voltage power distribution network is not available. When the power supply bureau knows which low-voltage power distribution user area has power failure and then arranges a maintenance plan mainly through a mode that a user reports failure to a power supply customer service, compared with real-time alarm, the mode greatly prolongs the power restoration time, seriously influences the user power consumption experience of a client, and reduces the power consumption satisfaction of the client, so a set of system for performing online diagnosis on the power failure of the low-voltage user and issuing the power failure alarm in real time is needed to solve the problems. The invention realizes the on-line monitoring and diagnosis of the power failure of the low-voltage users by utilizing the telecommunication terminal equipment, defines the power failure range of the low-voltage users by fuzzy matching, confirms the low-voltage users who actually have power failure in the range after verification and issues the power failure fault warning of the low-voltage users.
Because the number of low-voltage users is very large, and the installation and maintenance cost of online monitoring equipment is considered, the power failure fault can not be diagnosed by installing a special fault online monitoring device at each node like a main network and a distribution network, so that the current determination of power failure of the low-voltage users is mainly to inform customer service by the user through telephone, network media and other ways, and the customer service is confirmed and verified and then sends a maintenance work order for processing. The mode has low efficiency and long electricity recovery time, influences the electricity utilization experience of users and needs to be improved urgently. The invention aims at the problem to realize the monitoring and diagnosis of the power failure of the low-voltage user by using the existing telecommunication end equipment (such as a telephone, a data terminal, a microcomputer, a fax machine, a television and the like) of the user end.

In order to achieve the technical effects, the technical scheme of the invention is as follows:
a method for diagnosing low-voltage user power failure by utilizing telecommunication terminal equipment comprises the following steps:
step S1: acquiring internet fault data of a telecommunication broadband user in real time through a telecommunication ANISS system and a network management system; acquiring equipment cascade information, an equipment installation address and a user installation address through a resource system;
step S2: data from an ANISS system and a resource system are subjected to field combing and cleaning conversion (ETL processing), and then the data are integrated together to form data information containing the internal number of the alarm equipment, the name of the equipment, the user corresponding to the equipment, the latitude and longitude of the user of the equipment, the formatted address of the user of the equipment (province/city/town/street/district/street and seat number), the alarm type of the equipment, the alarm state (action/return) of the equipment and the alarm time of the equipment;
step S3: analyzing data by using a data model at a warehouse layer, filtering according to equipment alarm types, filtering out equipment alarm records caused by low-voltage power failure, removing information fields, blanking sensitive fields such as specific user names and equipment names, and forming an alarm output format as follows: the internal number of the alarm device, the latitude and longitude of the user corresponding to the device, the format address (province/city/town/street/cell/street and seat number) of the user corresponding to the device, the alarm state (action/reset) and the alarm generation time, and the process goes to step S4; if the equipment alarm category is not caused by the power supply fault, the power failure alarm information is not output to the power supply bureau, the process is ended, and the next cycle is skipped;
step S4: the telecommunication side alarm information and the power supply station distribution automation system information are combined for judgment: when the power supply bureau is used for low-voltage power failure analysis, a longitude and latitude fault point of fault equipment provided by telecommunication equipment is taken as a center, a suspected low-voltage user power failure is judged at a low-voltage user fire point position within a certain radius range, whether equipment power failure exists on an upstream power supply path is searched from the user fire point, if known medium-voltage switch power failure and medium-voltage distribution transformer power failure exist, the information is discarded, and the next cycle is skipped; if the power failure of the corresponding medium-voltage switch and the power failure of the medium-voltage distribution transformer are not matched, jumping to the step S5;
step S5: the formatted address of a low-voltage user fire point is matched with a formatted address (province/city/town/street/cell/street and seat number) of a fault device corresponding to a user provided by telecommunication equipment in a fuzzy manner, if the address of a relevant fire point can be matched, whether equipment power failure exists on a power supply path at the upstream is searched from the fire point of the user, if known medium-voltage switch power failure and medium-voltage distribution transformer power failure exist, the information is discarded, and the next cycle is skipped; if the power failure of the corresponding medium-voltage switch and the power failure of the medium-voltage distribution transformer are not matched, the step S6 is skipped;
step S6: and 4, generating an unknown low-voltage user power failure warning by using the fact that the related low-voltage fire drop points with known medium-voltage power failure cannot be matched in the steps 4 and 5, simultaneously outputting information such as failure occurrence time, failure point positions and the number of affected users, automatically generating a maintenance work order, and informing a power supply service worker to verify and confirm whether the user has power failure actually.
Compared with the prior art, the technical scheme of the invention has the beneficial effects that:
the method utilizes an ANISS system to monitor the Internet surfing state of a Foshan city power telecommunication broadband user, when a power supply bureau receives real-time alarm information from the ANISS system, if the fact that a batch user offline fault is caused by power failure is judged, power failure alarm information is output to the power supply bureau in real time, then the power supply bureau combines the telecommunication side alarm information with the power distribution automation system alarm information to judge whether the power failure occurs to a low-voltage user, and if the power distribution automation system does not receive the power failure alarm information at the moment, the power failure fault possibly occurs to the low-voltage user is judged. Because the position sent by the telecommunication terminal equipment has a certain deviation from the actual geographic position of the user, fuzzy matching is carried out on the position fed back by the telecommunication terminal equipment: the method comprises the steps of setting a fault point as a center, judging a low-voltage user in a certain radius range as suspected low-voltage user power failure, filtering out power failure events such as scheduled maintenance power failure and medium-voltage fault power failure which can be sensed by a system, automatically issuing a low-voltage user power failure fault warning, automatically generating a maintenance work order, and informing a worker to verify and confirm whether a user actually has power failure so as to improve the sensing capability of the office on the low-voltage fault.
