In addition, the server 104 may also send the target alarm signal and the alarm identifier of the target alarm signal to the failure fast power restoration emergency repair command terminal 106 or the customer service system terminal 108 for display. The command terminal 106 or the customer service system terminal 108 for rapid electrical restoration repair of a fault may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 102 and the server 104 may be implemented by independent servers or a server cluster formed by a plurality of servers.
In practical application, based on an operation bus of an OSB (power grid operation management system), two parts of contents of an original alarm signal (namely Acquisition of the original alarm signal) And a reference alarm signal (namely generation of the reference alarm signal) are obtained And can be centrally deployed on the same server, or can be deployed on different nodes according to a classification application module, for example, steady-state operation monitoring alarm information And a steady-state operation monitoring reference signal are deployed And acquired on a SCADA (Supervisory Control And Data Acquisition) node, And the transient operation monitoring alarm information And the transient operation monitoring reference signal are generated And deployed on a messenger node. The contents of the target alarm signal (i.e. the processing of the reference alarm signal) screened from the reference alarm signal and the intelligent inference of the target alarm signal are intensively deployed in the same server, so as to improve the inference analysis efficiency. And finally, displaying the target alarm signal and the identifier of the target alarm signal, wherein the target alarm signal, the reference alarm signal processing and the target alarm signal intelligent reasoning deployment can be arranged in the same server, and can also be independently arranged in other nodes, and the system function deployment should meet the N-1 redundancy requirement. The functions of acquisition of an original alarm signal, generation of a reference alarm signal, intelligent inference of a target alarm signal and the like are deployed in a safety production I area (namely a real-time control area), the marks of the target alarm signal and the target alarm signal are displayed, and a related analysis function can be deployed in a safety I area or a safety III area according to needs.
In one embodiment, as shown in fig. 2, a method for processing operation failure of a power distribution network is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and includes the following steps:
step S202, original alarm signals of each operating device are obtained from the power distribution network monitoring system, and the original alarm signals are classified to obtain reference alarm signals.
The original alarm signal in this embodiment mainly refers to a remote sensing signal (such as switch deflection information) and a remote sensing signal (such as an alarm signal that parameters such as voltage and current of a power grid device acquired at regular time are abnormal), and the original alarm signal carries alarm time and alarm device information.
In a specific implementation, a power distribution network monitoring system (or an application module) collects a fault state signal of power distribution network operating equipment from monitoring equipment (such as a sensor) arranged at the power distribution network operating equipment (such as a circuit) to serve as an original alarm signal. The server 104 acquires original alarm signals of the power distribution network operation equipment from one or more power distribution network monitoring systems, and classifies and combines the original alarm signals according to predefined reference alarm signal types and matching generation rules of each reference signal type and the corresponding original alarm signals to obtain various reference alarm signals of intelligent alarm. The reference alarm signal type and the matching generation rule of the corresponding original alarm signal are shown in the following table 1, wherein the 1 st column in the table represents the reference alarm signal type and further subdivides the reference alarm signal under each reference alarm signal type, the second column represents the reference alarm signal type, the third column represents the corresponding alarm device type, and the fourth column represents the corresponding original alarm signal. For example, if the original alarm signal obtained by the server 104 is one of an abnormal fault recorder, an alarm of the fault recorder, a lock of the fault recorder, or a power failure of the fault recorder, the original alarm signal is classified into an abnormal fault recorder class in which the type of the reference alarm signal is the equipment monitoring class, and the equipment type corresponding to the original alarm signal is the fault recorder.
TABLE 1
More specifically, for example, in the functional architecture diagram for implementing the method for processing the operation fault of the power distribution network shown in fig. 3, the raw alarm signals are collected from the application modules (the device monitoring module, the energy-saving and environment-friendly monitoring module, the environment monitoring module, the transient monitoring module, the dynamic monitoring module, and the steady monitoring module) through the OSB operation service bus, and the raw signals such as the device monitoring raw signal, the energy-saving and environment-friendly raw signal, the online pre-warning raw signal, the environment monitoring raw signal, the transient monitoring raw signal, the dynamic monitoring raw signal, and the steady monitoring raw signal are obtained as the raw alarm signals. After the original alarm signal is obtained, the original alarm signal is classified and combined according to the reference signal classification and generation rules to obtain a reference signal (namely, a reference alarm signal).
Step S204, screening out a target alarm signal from the reference alarm signal; the target alarm signal is a reference alarm signal meeting a preset condition.
In a specific implementation, after the server 104 obtains the reference alarm signal, the reference alarm signal is further analyzed and processed, the reference alarm signal is filtered by using a preset filtering condition, and an invalid reference alarm signal is filtered out, so that a target alarm signal is obtained, and the target alarm signal is used as an input signal for reasoning and is stored in a database. The processing of the reference alarm signal includes, but is not limited to: the method comprises the steps of carrying out alarm blocking on an associated signal generated when equipment normally operates, and marking and filtering a reference alarm signal generated in a non-operation state such as equipment maintenance, debugging or cold standby state.
Step S206, acquiring the alarm mark of the target alarm signal.
The warning identifier may be divided according to different requirements, for example, the warning identifier may include an instantaneous fault identifier and a permanent fault identifier, and may also include a switch displacement information identifier in a substation and a switch displacement information identifier in a non-substation.
In a specific implementation, after obtaining the target alarm signal, the server 104 performs fault diagnosis on the target alarm signal, and determines an alarm identifier of the target alarm signal according to a fault diagnosis result. For example, if the fault can be automatically repaired after the occurrence of the fault (i.e. the time when the switch coincidence succeeds can be obtained), the alarm identifier of the target alarm signal is determined as an instantaneous fault, whereas if the fault cannot be automatically repaired after the occurrence of the fault (i.e. the time when the switch coincidence cannot be obtained), the alarm identifier of the target alarm signal is determined as a permanent fault.
Step S208, generating a corresponding fault processing list according to the alarm identifier of the target alarm signal; and the fault processing unit is used for informing maintenance personnel to maintain the alarm equipment.
In a specific implementation, after the alarm identifier of the target alarm signal is obtained, the server 104 may be triggered to call a fault handling list generation instruction corresponding to the alarm identifier of the target alarm signal, and generate a fault handling list corresponding to the alarm identifier of the target alarm signal, so that the equipment maintenance staff may perform fault emergency repair or patrol on the alarm equipment according to the fault handling list.
In the method for processing the operation fault of the power distribution network, the original alarm signal is obtained from the power distribution network monitoring system, the original alarm signal is classified to obtain the reference alarm signal, the target alarm signal is screened from the reference alarm signal to obtain the alarm mark of the target alarm signal, and finally, the corresponding fault processing instruction is generated according to the alarm mark of the target alarm signal to inform the processing personnel to maintain the alarm equipment, the method starts from the generation of the alarm signal of the power distribution network operation equipment, processes the original alarm signal step by obtaining the original alarm signal, and finally, after the alarm mark is determined, the processing personnel is informed to process the alarm equipment by the generation of the fault processing instruction, thereby realizing the uniform scheduling from the occurrence of the fault of the power distribution network operation equipment to the notification of the processing personnel, the association relation between the two is established, faults can be found in time, and processing personnel are informed to maintain in time, so that the processing efficiency of the operation faults of the power distribution network is improved, and the power supply reliability is improved.
In an embodiment, the step S204 specifically includes: acquiring signal parameters of a reference alarm signal; filtering the reference alarm signal by adopting a preset parameter filtering condition to obtain a reference alarm signal of which the signal parameter meets the parameter filtering condition as a target alarm signal;
and/or acquiring a signal label of the reference alarm signal; filtering the reference alarm signal by adopting a preset label filtering condition to obtain a reference alarm signal of which the signal label meets the label filtering condition as a target alarm signal; the signal label with the label filtering condition of the reference alarm signal is in a non-running state;
and/or, filtering the reference alarm signal by adopting a preset alarm blocking condition to obtain a reference alarm signal which does not meet the alarm blocking condition and is used as a target alarm signal; the alarm lockout condition is that the reference alarm signal is a companion signal generated when the device is operating normally.
The signal parameters may include parameters such as time, area, station, voltage level, interval, device, alarm type, alarm level, and alarm object.
The signal tags can be divided into non-operating state tags and operating state tags, and the non-operating state tags can comprise overhaul, debugging and cold standby.
In a specific implementation, when the server 104 performs filtering processing on the reference alarm signal, the preset parameter filtering condition may be used to filter the reference alarm signal that does not meet the requirement of the signal parameter, and the reference alarm signal whose signal parameter meets the parameter filtering condition is obtained as the target alarm signal. The parameter filtering condition may be a filtering condition obtained by combining any number of parameters in the signal parameters, for example, the parameter filtering condition may be a set alarm object in a set time range and a set region. And/or identifying the equipment/interval/station hung with the overhaul board, the debugging board and the cold standby board, making reference alarm signals generated by the equipment/interval/station as corresponding labels, and after determining the signal label of the reference alarm signals, filtering the reference alarm signals of the signal labels which are non-running state labels (namely, the reference alarm signals meet the label filtering condition) such as overhaul, debugging, cold standby and the like to obtain the reference alarm signals which do not meet the label filtering condition as target alarm signals. And/or, filtering the reference alarm signal by adopting a preset alarm condition, acquiring a time blocking range, carrying out alarm blocking on the reference alarm signal which is in the time blocking range and belongs to an associated signal (namely, the reference alarm signal meets the alarm blocking condition) generated when the equipment is normally operated, and acquiring the reference alarm signal which does not meet the alarm blocking condition as a target alarm signal.
In this embodiment, the reference alarm signal is filtered through the preset parameter filtering condition, the preset tag filtering condition, the preset alarm blocking condition, and the like, and the target alarm signal is obtained by screening from the reference alarm signal, so that the problems that the workload of the server is increased and the time is consumed due to the existence of an invalid reference alarm signal when the reference alarm signal is further processed can be solved.
In an embodiment, the step S206 specifically includes: carrying out fault diagnosis processing on the target alarm signal to obtain the alarm behavior of the target alarm signal; and inquiring the corresponding relation between the preset alarm behavior and the alarm identifier according to the alarm behavior of the target alarm signal to obtain the alarm identifier of the target alarm signal.
The alarm behavior represents specific actions of alarm, as shown in table 2 below, which is an example of the alarm behavior, a first column in the table represents a device name of a power distribution network operating device, and a second column represents some alarm behaviors corresponding to each alarm device, for example, for a line of a power distribution network, the alarm behavior may be an accident trip, a reclosing success, an accident trip, an reclosing failure, an accident trip, a reclosing failure, and the like.
In a specific implementation, after the server 104 obtains the target alarm signal, it may perform intelligent fault diagnosis on the target alarm signal to obtain a fault diagnosis result, which is used as an alarm behavior of the target alarm signal, and determine an alarm identifier of the target alarm signal according to the alarm behavior of the target alarm signal and a preset corresponding relationship between the alarm behavior and the alarm identifier. For example, in table 2, if the fault diagnosis result of the line indicates that the line has failed to trip and successfully reclosed, which indicates that the line fault has been automatically repaired, the fault identifier corresponding to the alarm behavior may be determined to be an instantaneous fault according to the corresponding relationship between the preset alarm behavior "failed to trip and successfully reclosed" and the instantaneous fault identifier.
