Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] Example

[0021] like Figure 1As shown, this embodiment provides a fault signal automatic call system based on a centralized monitoring system, including a fault signal acquisition module, a fault signal analysis module, a multi-party call module, a centralized control system emergency response module, and an information feedback module. The fault signal acquisition module is used to collect fault signals in the alarm window of the centralized control system, and set a signal acquisition time interval to identify and eliminate the erroneous fault signals that automatically return in a short time, so as to realize real-time acquisition of signals; the fault signal analysis module is used to perform real-time analysis and judgment on the fault information collected in the alarm window, quickly match the fault signal with the local fault signal library, and analyze the fault information in real time; the multi-party call module is used to automatically dial calls through the intranet phone of the centralized control station team, and send SMS notifications to trip signals at the same time, so as to realize simultaneous information communication to multiple departments; the centralized control system emergency response module is used to monitor the operation of the substation in real time, realize rapid response to substation faults and take corresponding measures; the information feedback module is used to automatically dial calls after the fault signals collected in the alarm window of the centralized control system return to normal, so as to realize simultaneous information communication to multiple departments.

[0022] As a further solution of the present invention, the fault signal acquisition module includes a fault signal acquisition module, a fault signal processing module and a fault signal storage module.

[0023] As a further solution of the present invention, the fault signal acquisition is used to collect data on the fault signals in the alarm window of the centralized control system, and the collected signals include tripping signals, current over-limit signals, grounding signals, communication interruption of the measurement and control device and other fault signals; the fault signal processing module is used to process the fault signals in the alarm window of the centralized control system. There will be many fault signals that are sent by mistake in the alarm window. A time delay is set for the collected signals, and the signals are collected and compared again after 5 minutes, and the signals that have been restored are identified and eliminated. In particular: 1. Tripping and grounding faults are basically not sent by mistake, and the signals are important, so there is no need to set a delay. 2. The current over-limit often suddenly exceeds the upper limit, and then restores in a very short time, and there is no need to set a delay. Once the limit is exceeded, the dispatching and allocation personnel must be reminded; the fault signal storage module is used to store the processed fault signals, filter the information of different channels, add data tags to the corresponding information, and wait for the next step of processing.

[0024] As a further solution of the present invention, the fault signal analysis module includes a signal screening module and a fault matching module; the signal screening module is used to quickly identify and screen the fault signal data, extract important signals and generate event-based alarms by comparing the local fault storage library, and analyze accurate fault information; Figure 2 As shown, the fault matching module is used to notify different departments of different signals, as follows:

[0025] If the signal contains one or more keywords of main transformer, 35kV, 110kV, 220kV, precision cut safety device, and full station exit, the dispatching department and the operation and maintenance department will be notified;

[0026] If the signal contains the 10kV keyword, the dispatching department and the operation and maintenance department will be notified;

[0027] The signal contains the keyword of abnormal protection channel, and notifies the dispatching department, maintenance department, information and communication department, and operation and maintenance department;

[0028] If the signal contains one or more keywords selected from the group consisting of abnormal communication of the measurement and control / measurement and protection device, communication failure of the measurement and control / measurement and protection device, communication interruption of the measurement and control / measurement and protection device, protection exit, total accident, and energy storage motor failure, the maintenance department and the operation and maintenance department are notified;

[0029] If the signal is other signals, the operation and maintenance department is notified.

[0030] As a further solution of the present invention, the multi-party call module includes a telephone call module, a text message sending module, and a service delay automatic re-call module; the telephone call module is used to automatically trigger the multi-party call button to automatically call after the fault signal analysis module analyzes the event alarm, realizes automatic intercom and sends out event alarm information; the text message sending module is used to send some important alarm information such as tripping, main transformer heavy gas signal action and other signals to the mobile phones of the persons in charge of the relevant departments through the text message platform, so as to notify a wider range;

[0031] like Figure 3 As shown, if a tripping or grounding fault occurs, since a large number of accompanying signals are generated, the alarm information cannot be directly sent to the person in charge of the relevant department, and the signal needs to be sorted and sent.

[0032] If a trip occurs:

[0033] 1) Check whether the “reclosing switch exit” appears in the alarm. If so, it proves that the reclosing switch has been activated.

[0034] 2) Read the switch position to verify whether the switch is successfully closed;

[0035] 3) If there is "reclosing exit" information, the final switch is in the closed position, and the reclosing may be successful, or the reclosing may fail and the FA self-healing may be successful;

[0036] 4) If there is no "reclosing exit" information, and the dispatcher / dispatcher has not closed the switch, but the switch is closed, it proves that FA self-healing is successful.

[0037] The corresponding SMS template after the sound trip is as follows:

[0038] Voice + SMS template 1: Monitoring personnel ×, × time × minute, × station × line tripped, the reclosing switch was actuated, but reclosing failed.

[0039] Voice + SMS template 2: Monitoring personnel ×, × time × minute, × station × line tripped, reclosing action was taken, and reclosing was successful.

[0040] Voice + SMS template 3: Monitoring personnel ×, × time × minute, × station × line tripped, the switch is in the open state.

[0041] Voice + SMS template 4: Monitoring personnel ×, × time × minute, × station × line tripped, FA self-healed successfully.

[0042] If a ground fault occurs:

[0043] The grounding of 35kV and 10kV busbars will be accompanied by a large number of abnormal signals from the measurement and protection devices of the same busbar line due to the grounding.

[0044] Template for telephone notification of ground fault:

[0045] At ×, × time and × minute, the monitoring personnel found that the × busbar at × station was grounded, and the small current line selection device selected the × line (if there is a line selection device).

[0046] The service delay automatic re-call module is used to make a multi-party automatic call. If some departments among the departments do not receive the fault alarm call, the call will be made again in time until the call is connected.

[0047] As a further solution of the present invention, the emergency response module of the centralized control system includes an auxiliary control response module and a path planning module; the auxiliary control response module is used to take corresponding emergency measures for auxiliary control facilities such as lighting and air conditioning of the substation according to the event alarm information; the path planning module is used to add a fault handling vehicle path planning module when multiple substations fail at the same time, and plan the shortest route through GPS positioning of each substation to efficiently handle the fault.

[0048] As a further solution of the present invention, the information feedback module is used to automatically dial a number after the fault information collected by the alarm window of the centralized control system is restored, so as to realize the information transmission to multiple departments at the same time.
