Description

Method and system for processing equipment data and repair work order data of distribution network fault

Technical Field

The invention belongs to the technical field of power dispatching, and particularly relates to a system module for providing distribution network fault information suitable for unified dispatching and unified release to other modules of a power supply service command platform in the power supply service command platform.

Background

The distribution network, namely the distribution network, is a power network which receives electric energy from a step-down distribution substation and distributes the electric energy to various users on site or step by step according to voltage through distribution facilities, and mainly comprises distribution equipment for primary measurement and auxiliary equipment on a secondary side, wherein the distribution equipment mainly comprises switch equipment, a distribution line and a distribution transformer.

Different information management systems are generally deployed for the management of the power distribution network in the power enterprise according to different demand angles, and the information management systems mainly include the following systems.

The intelligent power grid dispatching control system is an automatic system for intelligent power grid dispatching production business, provides technical support for the businesses such as power grid operation monitoring, operation control, safety analysis, planning, auxiliary decision making, dispatching management and the like, and can provide real-time information and historical information of a substation outgoing switch through a database.

A distribution automation system, DAS, is an automated system that enables an electric utility to monitor, coordinate, and operate distribution equipment remotely in real time, providing real time information and historical information of line branch switches via its database.

The equipment operation and maintenance lean management system is also called an asset operation and maintenance lean management system, namely PMS, and is a set of service basic software platform which is developed based on model driving and component concept and faces to the power industry, wherein a database of the PMS comprises a full-grid equipment ledger, and equipment numbers and equipment names in the equipment ledger can be called through an interface.

The power consumption information acquisition system is a system for acquiring, processing and monitoring power consumption information of power consumers in real time, and realizes the functions of automatic acquisition of the power consumption information, abnormal metering monitoring, power quality monitoring, power consumption analysis and management, related information release, distributed energy monitoring, information interaction of intelligent power consumption equipment and the like. The electricity utilization information acquisition system can provide historical information of the electric energy meter and a calling and testing interface, and other systems can directly read the real-time information of the designated electric energy meter through the interface.

The GIS is mainly used for carrying out centralized management on information such as power transmission and distribution network equipment, facility space distribution data, production operation data, power grid operation state and the like of a power transmission and distribution backbone network and a backbone network by utilizing a geographic information technology, analyzing the network relation of a power grid, and integrating an existing information management system to form a comprehensive power grid management information system taking geographic information as support. The transmission and distribution grid geographic information system may provide a digital map containing the installation location of the electrical equipment.

The power supply service command platform is a power user service system deployed for a power supply service command center, realizes the integrated operation of commanding, coordinating, monitoring, analyzing and other services in the working process of power supply service, and has at least the following two technical requirements: a. centralizing data of each internal information management system to realize unified scheduling; b. and credible information disclosure is provided for external power consumers, and uniform distribution is realized. At present, the fault maintenance response process of the power distribution network in a power supply service command platform is as follows: 1. the call center inputs a fault repair work order into the equipment operation and maintenance lean management system after receiving a repair call of a user, wherein the fault repair work order comprises unconfirmed fault address information and is in an unprocessed state; 2. the power supply service command center calls an unprocessed fault repair work order in the equipment operation and maintenance lean management system, and dispatches the unprocessed fault repair work order to a first repair team group in charge of a repair area where an unconfirmed fault address in the work order is located; 3. the first emergency repair team group backtracks the power supply link of the power distribution network to find a fault point according to an unconfirmed fault address, if the fault point belongs to the jurisdiction of the first emergency repair team group, the maintenance time is evaluated and reported to a power supply service command center, if the fault point does not belong to the jurisdiction of the first emergency repair team group, the fault point is reported to the power supply service command center, the power supply service command center assigns a second emergency repair team group to continue to confirm the fault point, the step is repeated until the first emergency repair team group confirms that the fault point belongs to the jurisdiction of the first emergency repair team group, and the first emergency repair team group reports the evaluation maintenance time to the power supply service command center; 4. and after receiving the evaluation and maintenance time, the power supply service command center changes the fault repair work order into a maintenance state, evaluates the power failure range and sends a power failure notice to the power consumers registered in the power failure range by the mobile phone.

The distribution network fault information acquisition process of the current power supply service command platform at least has the following problems: 1. the power user number contained in the fault report and repair work order can only confirm the power supply station area to which the user belongs, but the power supply station area is different from the repair area, so that the power supply station area cannot be directly used for backtracking of a power supply link, and the power supply station area still needs to be manually moved to backtrack and be checked; 2. if the fault report repair work order does not contain the power user number, the fault report repair work order only contains fuzzy unconfirmed fault address information, is difficult to be used for manual sorting to determine the administration of a maintenance area, and even cannot be used for automatic sorting; 3. the information acquisition of the power supply service command center is lagged, the internal information management system cannot be directly opened to external power users, the real-time information interaction with power users cannot be technically realized, the whole power supply first-aid repair process is opaque, adverse effects are easily caused, and the technical requirement of the communication performance of the power supply service command platform is not met; 4. the running state of the distribution transformer substation, the states of the distribution transformer and the user ammeter, the states of the distribution line switch and the states of the fault repair work order belong to different information management systems, and each information management system has certain incompleteness, cannot directly provide reliable scheduling suggestions for a power supply service command center, needs manual processing, and has large workload; 5. distribution network automation equipment cannot fully cover and call and test incomplete transmission equipment of a system, and if the existing distribution network branch switches do not fully realize automation, informatization real-time query cannot be realized.

Chinese patent CN104965150B discloses a power distribution network fault location method based on incomplete operation and distribution information fusion, which locates faults by backtracking the power supply link and analyzing the weight of the alarm device in the power supply link. The method is based on the premise that the alarm equipment can be directly positioned on a specific line of a power supply station area, but in the practical situation, most power distribution network fault repair work orders only carry approximate address information, are almost irrelevant to the address of the fault power distribution equipment, and generally cannot determine the line and the specific number of the fault power distribution equipment through the fault work orders, so that the system is difficult to be practically applied to a power supply service command platform.

However, the first real-time device data or the second real-time device data often have a situation that the data cannot be received, and when only one of the three information management systems can be used, the distribution network fault information cannot be judged through the methods from S1 to S6, so that the power supply service command center completely loses command right. In order to solve the problems, the invention further utilizes the characteristics of the system and the collected historical equipment data to study and judge. Such as: when the power utilization acquisition system can normally acquire data, and the smart grid dispatching control system and the distribution automation system cannot acquire data when meeting the conditions of equipment maintenance and the like, the 100001, 100101, 100201 and 100301 transformers are covered at the upstream and the downstream of the branch switch, so to speak, as long as there is a transformer in the switch, the current and the voltage of the transformer at the upstream of the branch switch are not 0, and the current and the voltage of the transformer at the downstream are 0, so that the branch switch can be judged to have a fault. Besides, there are two extreme cases Q1, Q2, and the solution is as follows:

q1, when the data in the distribution automation system and the power utilization information acquisition system can not be obtained, the data of the line is recorded according to the time by judging through the previously stored data, such as the Guangan offline of the Guangan station 611 for example.

When the data in the power distribution automation system and the power utilization information acquisition system cannot be acquired. Firstly, judging time, if the time is 0 minutes at 3 months, 1 day and 0 month in 2019, calculating the average voltage of the outgoing line switch of the substation 10.7 and the average current of the outgoing line switch of the substation 80.9 at the time according to the data average values of 2016, 2017 and 2018 years, and if the average voltage of the outgoing line switch of the substation is 10.5, 10.6, 10.5 and the average current of the outgoing line switch of 1001, 1002 and 1003 is 71.2, 40.9 and 21.1 at the time, determining that the current value of the outgoing line switch is 88.0 percent of the current value of the outgoing line switch, the current value of the outgoing line switch of 1001 is 50.6 percent of the current value of the outgoing line switch, and the current value of the outgoing line switch of 1003 is 26.1 percent of the current value of the outgoing line switch under the normal condition at 0 minute at 3 months, 1 day and 0 month. That is, at this point in time, if the substation outlet switch current value decreases by 26.1%, it is determined that the 1003 switch has a fault, if it decreases by 50.6%, it is determined that 1002, and if it decreases by 88.0%, it is determined 1001 that the switch has a fault. And the judgment basis is that the upper part and the lower part float by 5 percent.

Q2, when the data in the smart grid dispatching control system and the power utilization acquisition system can not be obtained, judging through the previously stored data, for example, the Guangan station 611 carries out the Guangan offline, and the data of the line are recorded according to time.

When the data in the intelligent power grid dispatching control system and the power utilization information acquisition system cannot be acquired. First, the on-off state and the on-off state of the 1001, 1002, and 1003 switches are determined, but if both the voltage and the current are 0, it can be determined that the fault point is the substation outlet switch. Next, when the time is 0 minutes at 0 point of 3/1/2019, based on the average data values of three years of 2016, 2017 and 2018, the average voltages of the switches 1001, 1002 and 1003 are 10.5, 10.6 and 10.5, the average currents of the switches are 71.2, 40.9 and 21.1, the average voltages of the transformers 100101, 100201 and 100301 are 10.5, 10.6 and 10.5, and the average currents of the transformers 2.2, 3.2 and 2.1, it is determined that the transformer current value 100101 is 3.1% of the switch current value 1001, the transformer current value 100201 is 7.8% of the switch current value 1002, and the transformer current value 100103 is 10.0% of the switch current value 1003 under the normal condition of the line at 0 point of 1/3/1/day. That is, at this time point, if the branch switch current value is 3.1% below the 1001 switch, it is determined that the transformer below the 1001 switch is faulty, if the 1001 switch is 7.8% below, it is determined 1002 that the transformer below the 1003 switch is faulty, and if the 1003 switch is 10.0% below, it is determined 1003 that the transformer below the 1003 switch is faulty. And the judgment basis is that the upper part and the lower part float by 1 percent.
