Detailed Implementation

[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0051] Please see Figure 1 , Figure 1 This is a flowchart illustrating the steps of a power grid alarm monitoring method according to an embodiment of the present invention. The method is applied to an alarm information system, which includes an accident detection module and an automatic cruise module. Specifically, it may include the following steps:

[0052] Step S101: Collect real-time alarm signals generated by the alarm source;

[0053] Step S102: The automatic cruise module filters the real-time alarm signals according to the first preset filtering rules to obtain the filtered alarm signals.

[0054] Step S103: The automatic cruise module filters the filtered alarm signals according to the second preset filtering rules to obtain multiple alarm signals to be sent and written to an E format file.

[0055] Step S104: The automatic cruise module parses the alarm signal to be sent and synchronizes the alarm signal to be sent to the user terminal of the power supply and substation personnel through the internal and external network connection channel, and generates the voice text corresponding to the alarm signal to be sent; the voice text information is used to send to the client of the on-duty maintenance personnel in voice form;

[0056] Step S105: When the accident detection module detects a power grid accident, it generates a command to disable the specified cruise function.

[0057] In step S106, the automatic cruise module executes the cruise shutdown operation according to the specified cruise function shutdown command and generates the corresponding cruise shutdown operation voice text.

[0058] This invention, in its embodiments, collects real-time alarm signals generated by alarm sources. The automatic patrol module filters these signals according to a first pre-set filtering rule, obtaining filtered alarm signals. The automatic patrol module then filters these filtered alarm signals according to a second pre-set filtering rule, obtaining multiple alarm signals to be sent and written to an E-format file. The automatic patrol module parses these alarm signals and synchronizes them to the user terminal of the power supply and substation personnel via an internal / external network connection channel, generating corresponding voice text for each alarm signal. This voice text information is sent to the client of the on-duty maintenance personnel in voice format. When the fault detection module detects a power grid fault, it generates a specified patrol function shutdown command. The automatic patrol module executes the patrol shutdown operation according to the specified patrol function shutdown command and generates corresponding patrol shutdown operation voice text. This fundamentally prevents missed alarms and the security risks of missed alarm notifications, achieving inherent security for monitoring services.

[0059] Please see Figure 2 , Figure 2 This is a flowchart illustrating the steps of a power grid alarm monitoring method according to an embodiment of the present invention, applied to, for example... Figure 3 The power grid alarm monitoring system of the present invention shown herein includes a first GPS timing system 2 and a second GPS timing system 8, which are used to synchronize and calibrate the time of a zone dispatch automation system 5 and a monitoring automation module 7. The method may specifically include the following steps:

[0060] Step S201: Collect real-time alarm signals generated by alarm sources; the real-time alarm signals include: the area of ​​responsibility, alarm type, priority, voltage level, alarm time, signal status, and the substation to which the alarm originates;

[0061] In this embodiment of the invention, the real-time alarm signals generated by the alarm source are collected by the SCADA front-end acquisition module 1 and sent to the signal filtering module 2.

[0062] Step S202: According to the first preset filtering rule, the real-time alarm signal is filtered to obtain the filtered alarm signal;

[0063] In an optional embodiment, the real-time alarm signals are filtered according to a first pre-set filtering rule to obtain filtered alarm signals, including:

[0064] The system sequentially determines whether the responsibility area of ​​the real-time alarm signal is within the specified responsibility area, whether the alarm type belongs to the specified alarm type range, whether the priority belongs to the specified priority range, and whether the voltage level belongs to the specified voltage level range.

[0065] If so, then the real-time alarm signal is determined to meet the first preset filtering rule;

[0066] If not, then the real-time alarm signal will be removed.

[0067] In this embodiment of the invention, after receiving an alarm signal, the signal filtering module 2 filters out alarm signals within the specified responsibility area, the specified alarm type, the specified priority, and the specified voltage level according to the rules set in the program, namely the first pre-set filtering rules. If the filtering rules are met, the signal filtering module will transmit the alarm signal to the first-zone dispatch automation system 5.

[0068] Step S203: According to the second preset filtering rules, the filtered alarm signals are filtered to obtain multiple alarm signals to be sent and written to an E format file;

[0069] In an optional embodiment, the filtered alarm signals are filtered according to a second pre-set filtering rule to obtain multiple alarm signals to be sent and written to an E-format file, including:

[0070] The alarm time of the filtered alarm signal is determined sequentially to be greater than the preset alarm duration, whether the signal status belongs to the specified status type range, and whether the plant to which it belongs is a user station.

[0071] If so, then it is determined that the filtered alarm signal meets the second preset filtering rule, and the filtered alarm signal is defined as an alarm signal to be sent.

[0072] If not, then the filtered alarm signals will be removed.

[0073] In this embodiment of the invention, the zone dispatch automation system 5 stores the filtered alarm signals in an alarm signal list and sends the alarm signal list to the first automatic cruise module 4 at fixed time intervals (20 seconds). Then, the first automatic cruise module 4 writes the alarm signal list into an E-format file and transmits it to the second automatic cruise module 6 through forward isolation. The second automatic cruise module 6 then parses the E-format alarm signal list and filters the alarm signals in the filtered alarm signal list according to the sending judgment rule, that is, the second pre-set filtering rule, to obtain multiple alarm signals to be sent and written into the E-format file.

[0074] In specific implementation, the second pre-set filtering rules include: the alarm time of the filtered alarm signal is >5 minutes, the signal status is "action" or the signal status is "reset" and the number of action resets is greater than 3 (the three-zone automatic cruise module 2 will check the real-time alarm signal list L every 5 minutes. If there are 2 alarm signals with the same alarm point number in the alarm signal list L and the status is action and reset respectively, each group of 2 is counted as 1 action reset), and the plant station to which it belongs is a user station (that is, the current station is not a virtual plant station, such as the system station and the test station are both virtual plants stations).

[0075] If the filtered alarm signal meets the second preset filtering rule, the second automatic cruise module 6 will mark the filtered alarm signal as an alarm signal to be sent, store it in the list of alarm signals to be sent, and write the alarm signal to an E format file.

[0076] Once the list of alarm signals to be issued has been processed, the second automatic cruise module 6 will send the E-format file back to the first automatic cruise module 4 via reverse isolation.

[0077] Step S204: parse the alarm signal to be sent, and synchronize the alarm signal to be sent to the user terminal of the power supply and substation personnel through the internal and external network connection channel; and generate the voice text corresponding to the alarm signal to be sent; the voice text information is used to send to the client of the on-duty operation and maintenance personnel in voice form;

[0078] In this embodiment of the invention, after receiving the E-format file from the second automatic cruise module 6, the first automatic cruise module 4 parses the alarm signals in the E-format file one by one and sends them to the first-zone dispatch automation system 5. The first-zone dispatch automation system 5 immediately issues the specified alarm signal. After receiving the alarm signal issued by the first-zone dispatch automation system 5, the monitoring automation module 7 sends it to the third-zone closed-loop module 10. After receiving the alarm signal sent by the monitoring automation module 7, the third-zone closed-loop module 10 synchronizes the signal to the user terminal of the power supply and substation personnel through the internal and external network connection channel 12.

[0079] Step S205: Determine whether the time for which the voice text signal has an alarm window is greater than the preset alarm duration; if so, automatically send the voice text through the voice platform.

[0080] In this embodiment of the invention, after receiving an alarm signal from the first-zone dispatch automation system 5, the monitoring automation module 7 sends the alarm signal to the second automatic cruise module 6. The second automatic cruise module 6 calls the list of alarm signals to be sent and compares the alarm signals to be sent with the alarm signals in the list in turn. If the alarm signal has the same alarm time, alarm point number and priority, the signal is deleted from the list of alarm signals to be sent and a voice text is generated. Then, the mobile phone number of the shift leader is retrieved from the address book of the on-duty personnel and the mobile phone number and the generated voice text are sent to the monitoring automation module 7. After receiving the mobile phone number and voice text sent by the second automatic cruise module 6, if the alarm signal has an alarm window that has not been processed for more than 5 minutes, it is automatically sent through the voice platform 11. Specifically, the voice text is sent to the voice platform 11, and the voice platform 11 generates voice according to the voice text and dials the designated phone number to broadcast the voice message.

[0081] Step S206: When a power grid fault is detected, a command to disable the specified cruise function is generated;

[0082] Step S207: Execute the cruise control shutdown operation according to the specified cruise control shutdown command, and generate the corresponding cruise control shutdown operation voice text.

[0083] In this embodiment, if the accident monitoring module 7 detects a power grid accident, it immediately sends a command to the second automatic cruise module 6 to disable the designated cruise function. Upon receiving this command, the second automatic cruise module 6 immediately stops parsing the E-format file, then writes the command into the E-format file and sends the file to the first automatic cruise module 4 via reverse isolation. The first automatic cruise module 4 receives the E-format file, parses the command, and immediately feeds back to the first-zone dispatch automation system 5. Simultaneously, it generates a voice reminder text, in the format: "Due to a detected accident, the automatic cruise mode is disabled. Please turn it on after the accident is handled or one hour later." Then, it retrieves the shift leader's mobile phone number from the on-duty personnel's contact list and sends the mobile phone number and the generated voice text information to the monitoring automation module 7. Upon receiving the mobile phone number and voice text information from the second automatic cruise module, the monitoring automation module 7 sends the information to the voice platform 11. The voice platform 11 then generates voice from the text information and dials a designated number for voice broadcast.

[0084] This invention collects real-time alarm signals generated by alarm sources; filters these signals according to a first pre-set filtering rule to obtain filtered alarm signals; filters these signals again according to a second pre-set filtering rule to obtain multiple alarm signals to be sent, written to an E-format file; parses these alarm signals and synchronizes them to the user terminal of the power supply and substation personnel via an internal / external network connection channel; and generates voice text corresponding to the alarm signals to be sent. This voice text information is then sent to the client of the on-duty maintenance personnel in voice format. This fundamentally prevents missed alarms and the security risks of missed alarm notifications, achieving inherent security for monitoring services.
