BRIEF DESCRIPTION OF DRAWINGS

[0044] Figure 1 A structure diagram of a power supply service real-time fault handling system. DETAILED DESCRIPTION

[0045] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. The embodiments described in the present application are only a part of the embodiments of the present application, but not all the embodiments. Based on the spirit of the present application, other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0046] As shown in Figure 1 Embodiment 1 of the present application provides a power supply service real-time fault handling system, which comprises a fault signal integration module, a fault positioning analysis module and a fault event publishing module.

[0047] In a preferred but non-limiting embodiment of the present application, the fault signal integration module is configured to acquire power failure alarm signals of each alarm terminal in real time, and to screen and integrate each acquired power failure alarm signal based on a plurality of time length thresholds to obtain a power failure alarm combination signal.

[0048] Further preferably, the fault signal acquisition module comprises a plurality of time length threshold signal acquisition units, an error signal elimination unit, an interference signal elimination unit and a signal integration unit.

[0049] The signal acquisition unit is configured to acquire power failure alarm signals of each alarm terminal in real time, to analyze each acquired power failure alarm signal, and to set a power restoration time of each alarm terminal according to an analysis result of the power failure alarm signal.

[0050] The error signal elimination unit is configured to determine whether the power failure alarm signal is an error signal according to the analysis result of the power failure alarm signal, and to eliminate the power failure alarm signal determined as the error signal.

[0051] The interference signal elimination unit is configured to determine whether the power failure alarm signal is an interference signal according to the analysis result of the power failure alarm signal and the power restoration time, and to eliminate the power failure alarm signal determined as the interference signal.

[0052] The signal integration unit is configured to integrate the power failure alarm signal after eliminating the error signal and the interference signal as the power failure alarm combination signal.

[0053] The error signal elimination unit and the interference signal elimination unit can eliminate the error signal and the interference signal in the power failure alarm signal respectively, so as to ensure the reliability of the power failure alarm combination signal after integration.

[0054] The signal acquisition unit, when analyzing each power failure alarm signal, if the power failure at the location of the alarm terminal corresponding to the power failure alarm signal has not been restored, only the power failure time and the power failure duration are parsed from the power failure alarm signal, and if the power failure at the location of the alarm terminal corresponding to the power failure alarm signal has been restored, the power restoration signal, the three-phase power parameters and the parameter acquisition time of the three-phase power parameters are further parsed from the power failure alarm signal.

[0055] When the power restoration time of each alarm terminal is set correspondingly, if the power restoration signal and the three-phase power parameters are parsed from the power failure alarm signal, it indicates that the power failure has been restored, and then it is further judged whether the difference between the parameter acquisition time and the power failure time is less than a preset first time threshold, the setting range of the first time threshold is 8-16 seconds, and preferably 12 seconds.

[0056] If the difference is less than the first time threshold, the power restoration time of the alarm terminal is set as the parameter acquisition time minus a preset power restoration duration threshold, the setting range of the power restoration duration threshold is 2-5 seconds, and preferably 3 seconds.

[0057] If the difference is greater than or equal to the first time threshold, the power restoration time of the alarm terminal is set as the current time.

[0058] If the power restoration signal and the three-phase power parameters are not parsed from the power failure alarm signal and the power failure duration is greater than a preset second time threshold, the setting range of the second time threshold is 18-36 seconds, and preferably 26 seconds, the power restoration time of the alarm terminal is set as the sum of the power failure time and the second time threshold, and if the power restoration signal and the three-phase power parameters are not parsed from the power failure alarm signal and the power failure duration is less than or equal to the preset second time threshold, the power restoration time is not set temporarily, and is set when it is greater than the second time threshold.

[0059] The power restoration time of the alarm terminal can be set correspondingly according to the parameter analysis result of the power failure alarm signal by the signal acquisition unit, thereby providing parameter support for subsequent interference signal elimination.

[0060] When the interference signal elimination unit judges whether the power failure alarm signal is an interference signal, the theoretical power failure duration is calculated by subtracting the power failure time from the power restoration time, if the theoretical power failure duration is less than a preset sixth time threshold, the setting range of the sixth time threshold is 2-8 seconds, and preferably 5 seconds, the power failure alarm signal corresponding to the alarm terminal is determined as an interference signal, otherwise as a non-interference signal.

[0061] The interference signal elimination unit can determine whether the power failure alarm signal is an interference signal according to the calculated theoretical power failure duration, thereby eliminating the interference signal in the power failure alarm signal and enhancing the reliability of the power failure alarm signal.

[0062] In the error signal elimination unit, according to the corresponding relationship between each power failure alarm signal and the alarm terminal, the number of power failure alarm signals sent by each alarm terminal is counted;

[0063] If the number of power failure alarm signals sent by a certain alarm terminal within a preset third time threshold is greater than an alarm preset number, the setting range of the third time threshold is 5-20 seconds, preferably 15 seconds, and the setting range of the alarm preset number is 5-10, preferably 8, then each power failure alarm signal corresponding to the alarm terminal is determined as an error signal;

[0064] If there is normal voltage data and current data of a certain alarm terminal within a preset fourth time threshold, the setting range of the fourth time threshold is 15-25 seconds, preferably 20 seconds, then each power failure alarm signal corresponding to the alarm terminal is determined as an error signal;

[0065] If the difference between the receiving time and the power failure time of a certain power failure alarm signal of a certain alarm terminal is greater than a fifth time threshold, the receiving time refers to the time when the system receives the power failure alarm signal, and the setting range of the fifth time threshold is 55-80 seconds, preferably 65 seconds, then the power failure alarm signal of the alarm terminal is determined as an error signal;

[0066] In addition to the above cases, it is determined as a non-error signal.

[0067] The error signal elimination unit can filter and eliminate the error signals in the power failure alarm signals, further enhancing the reliability of the power failure alarm signals.

[0068] The fault event generation module is configured to analyze the topological relationship of each alarm terminal according to the power failure alarm combination signal, analyze the number ratio of alarm terminals and branch terminals corresponding to the connection of the upper branch switch according to the topological relationship, combine the secondary proportion threshold to obtain a suspected fault device, and generate a suspected fault power failure alarm event.

[0069] Further preferably, the fault event generation module comprises a topological relationship analysis unit and an alarm event generation unit.

[0070] The topological relationship analysis unit is configured to analyze each alarm terminal in the power failure alarm combination signal (i.e., analyze which alarm terminal each signal in the combination signal corresponds to), and obtain the topological relationship of each alarm terminal according to the connection relationship of each alarm terminal in the power grid.

[0071] The alarm event generation unit is used to determine the superior branch switch of each alarm terminal based on the topological relationship and the branch terminals connected to each superior branch switch. The alarm terminal belongs to the branch terminal (i.e., the terminal connected to the branch corresponding to the superior branch switch is called the branch terminal, wherein the alarm terminal is the branch terminal of the alarm), and then the number of alarm terminals connected to the superior branch switch and the number ratio of branch terminals are determined in combination with the secondary proportion threshold to determine whether the superior branch switch is a suspected fault device. The suspected fault power outage alarm event is generated according to the judgment result of the suspected fault device, and the suspected fault power outage alarm event includes the related information of the suspected fault device and its superior branch switch, power outage information, and power restoration related information.

[0072] Further preferably, when the alarm event generation unit determines whether the superior branch switch is a suspected fault device, a first proportion threshold and a second proportion threshold are first set, and the first proportion threshold is less than the second proportion threshold, for example, the first proportion threshold is set to 85%, and the second proportion threshold is set to 95%. Then, the number of alarm terminals connected to the current superior branch switch and the number of branch terminals are counted, and then it is determined whether each alarm terminal connected to the current superior branch switch is also connected to other superior branch switches.

[0073] If no other superior branch switch is connected, the ratio of the number of alarm terminals connected to the current superior branch switch to the number of branch terminals is calculated as a first ratio. If the first ratio is greater than or equal to the first proportion threshold, the current superior branch switch is determined to be a suspected fault device. If the first ratio is less than the first proportion threshold, the current superior branch switch is determined to be a non-suspected fault device.

[0074] If other superior branch switches are also connected, the ratio of the number of alarm terminals connected to the current superior branch switch to the number of branch terminals is calculated as a second ratio. If the second ratio is greater than or equal to the second proportion threshold, the current superior branch switch is determined to be a suspected fault device. If the second ratio is less than the second proportion threshold, the current superior branch switch is determined to be a non-suspected fault device.

[0075] By analyzing the number of superior branch switches, different proportion thresholds can be selected according to the actual topological conditions. If there are multiple superior branch switches, the power outage information collected by the alarm terminal may come from one or more superior branch switches, which may cause misjudgment of the suspected fault device. Therefore, a higher proportion threshold is needed to distinguish, so that the judgment is more adaptive and the accuracy of the suspected fault device judgment is enhanced.

[0076] The fault event publishing module is used to determine whether the suspected fault power outage alarm event is a new power outage alarm event, and to send the new power outage alarm event to the target address according to the corresponding communication information when it is determined to be a new power outage alarm event.

[0077] Further preferably, the fault event publishing module comprises an event set comparison unit and an alarm event publishing unit;

[0078] The event set comparison unit is configured to compare the suspected fault power failure alarm event with each known power failure alarm event in a power failure alarm event set (a set of known power failure alarm events), and if there is a known power failure alarm event consistent with the suspected fault power failure alarm event (consistent in suspected fault equipment and its superior branch switch related information, power failure information and power restoration related information), the suspected fault power failure alarm event is determined as an existing power failure alarm event, otherwise the suspected fault power failure alarm event is determined as a new power failure alarm event.

[0079] The alarm event publishing unit is configured to determine the communication information corresponding to the new power failure alarm event according to the new power failure alarm event and the communication matching database, and send the new power failure alarm event to the target address corresponding to the communication information.

[0080] The event set comparison unit can determine whether the suspected fault power failure alarm event is a known power failure alarm event, thereby avoiding repeated alarm event publishing.

[0081] The alarm event publishing unit, when determining the communication information corresponding to the new power failure alarm event, first obtains each superior branch switch of the suspected fault equipment according to the new power failure alarm event, and then finds the corresponding communication information in the communication matching database by using the query number of each superior branch switch, wherein the communication information comprises a communication mode and a target address, the communication mode comprises telephone voice, short message or electronic mail, and the new power failure alarm event is sent to the corresponding target address by using the communication mode in the communication information, wherein the new power failure alarm event comprises superior branch switch related information (name, number, location information, etc.), power failure information (power failure time, theoretical power failure duration), power restoration related information (power restoration time, power restoration signal and three-phase power parameter) of each suspected fault equipment.

[0082] The alarm event publishing unit can quickly send the new power failure alarm event to the corresponding target address, which facilitates the staff to quickly carry out maintenance work and improves the fault disposal efficiency.

[0083] The system utilizes the fault signal integration module to screen and integrate each power failure alarm signal obtained into a power failure alarm combined signal, thereby effectively improving the processing efficiency of the power failure alarm signal without manual integration analysis; the fault event generation module can accurately analyze the suspected fault equipment and generate a suspected fault power failure alarm event, thereby realizing fault power failure range positioning; and the fault event publishing module can send the new power failure alarm event to the target address according to the corresponding communication information, thereby realizing quick and automatic publishing of the power failure alarm event and improving the fault repair efficiency.

[0084] Embodiment 2 of the present application provides a power supply service real-time fault handling method based on the above system, comprising the following steps:

[0085] Real-time acquisition of power failure alarm signals of each alarm terminal, and screening and integration of each power failure alarm signal obtained based on multiple time length thresholds to obtain a power failure alarm combined signal;
