Detailed Description
The embodiment of the invention provides a method and a device for automatically checking a remote measuring signal, electronic equipment and a storage medium, which are used for solving the technical problems of high labor cost and low checking efficiency of the conventional method for automatically checking the remote measuring signal.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a method for automatically checking a telemetry signal according to an embodiment of the invention.
The invention provides an automatic remote measuring signal checking method which is applied to a dispatching master station of a regional power grid, wherein the dispatching master station is communicated with a transformer substation; the method specifically comprises the following steps:
the transformer substation is a place for converting voltage and current, receiving electric energy and distributing electric energy in an electric power system.
In practical application, when a telemetering signal at a certain interval in a regional power grid is checked, a telemetering point for acquiring a telemetering signal needs to be determined at first. In an actual scene, the substation can send a debugging list information acquisition request to the scheduling master station to acquire a corresponding debugging list, wherein remote measuring point information of the substation at corresponding intervals is recorded in the debugging list.
102, analyzing the debugging list information acquisition request, and sending a target debugging list requested by the debugging list information acquisition request to the transformer substation;
after receiving the debugging list information acquisition request, the scheduling master station can send the requested target debugging list to the transformer substation according to the interval recorded in the debugging list information acquisition request.
103, receiving a starting request sent by the substation based on the target debugging list;
in the embodiment of the invention, after receiving the target debugging list sent by the dispatching master station, the transformer substation can generate the starting request based on the target remote measuring points and the check template recorded in the target debugging list, and send the remote measuring signals of the target remote measuring points to the dispatching master station based on the starting request.
In one example, the debugging steps of the substation and the debugging strategies of each debugging step can be recorded in the checking template, so that the substation can be debugged according to different debugging strategies in different debugging steps. In a specific implementation, after receiving the check of completing one debugging step fed back by the master station, the server of the substation may generate a debugging strategy for the substation based on the check template, and display the debugging strategy to a debugging person. After the debugging personnel select the option without error, the transformer substation can automatically adjust the parameters of the transformer substation based on the debugging strategy, such as automatically adjusting the voltage and current phase angle, and sends the corresponding remote measuring signals to the dispatching master station.
And 105, checking the telemetering signal based on the checking template to generate a checking result.
After the telemetering signals of the target telemetering points are collected, the scheduling master station can check the telemetering signals according to the corresponding debugging steps and theoretical results corresponding to the debugging steps based on the checking template to generate checking results.
The method comprises the steps of receiving a debugging list information acquisition request of a preset interval sent by a transformer substation; analyzing the debugging list information acquisition request, and sending a target debugging list requested by the debugging list information acquisition request to the transformer substation; receiving a starting request sent by a transformer substation based on a target debugging list; analyzing the starting request to determine a target remote measuring point and a checking template, and acquiring a remote measuring signal of the target remote measuring point; and checking the telemetering signal based on the checking template to generate a checking result. Therefore, people do not need to check the remote measuring signals, the labor cost is reduced, and the checking efficiency is improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a telemetry signal auto-verification method according to another embodiment of the invention. The method specifically comprises the following steps:
in the embodiment of the present invention, a maintenance workstation may be set in the scheduling master station, and the maintenance workstation is deployed with a scheduling list management tool. The dispatching list management tool can screen out remote measuring points to be debugged in the whole interval according to stations and intervals in the relational database, read information such as point IDs (identity) of the remote measuring points, point description, point number acquisition, RTU acquisition and the like, and organize the remote measuring points into a complete debugging list by combining the input work information. The generated debug list is then saved in a relational database.
in the embodiment of the invention, operation and maintenance personnel of the transformer substation can use the browser to request to acquire the debugging list information of a certain interval so as to acquire the corresponding debugging list.
It should be noted that, in order to ensure the security of data interaction between the master scheduling station and the substation, the debugging list acquisition request sent by the substation may be sent to the master scheduling station through the reverse isolation device. The dispatching master station can send the debugging list to the transformer substation through the forward isolation device.
after receiving the debugging list information acquisition request, the scheduling master station can send the requested target debugging list to the transformer substation according to the interval recorded in the debugging list information acquisition request.
In one example, step 205 may include the following sub-steps:
s51, extracting target remote measuring point parameters from the debugging list information acquisition request;
s52, matching target remote measuring point parameters in the relational database to obtain a target debugging list requested by a debugging list acquisition request;
and S53, sending the target debugging list to the transformer substation.
In the embodiment of the invention, the target remote measuring point parameters can comprise information such as point ID, point description, point number acquisition, RTU acquisition and the like. Based on the target remote measuring point parameters, a corresponding target debugging list can be obtained in a relational database in a matching mode.
in the embodiment of the invention, after receiving the target debugging list sent by the dispatching master station, the transformer substation can generate the starting request based on the target remote measuring points and the check template recorded in the target debugging list, and send the remote measuring signals of the target remote measuring points to the dispatching master station based on the starting request.
And step 208, checking the telemetric signal based on the checking template to generate a checking result.
After the telemetering signals of the target telemetering points are collected, the scheduling master station can check the telemetering signals according to corresponding debugging steps and theoretical results obtained in the debugging steps based on the checking template to generate checking results.
In a particular implementation, the telemetry signals may include an active real-time value, a reactive real-time value, an a-phase current real-time value, a B-phase current real-time value, and a C-phase current real-time value. Each telemetry signal has a corresponding fullness value.
In one example, the collation process based on the collation template may be as follows:
1. when the equipment of the transformer substation is connected and is not electrified, detecting whether an active real-time value, a reactive real-time value, an A-phase current real-time value, a B-phase current real-time value and a C-phase current real-time value are all 0, if yes, entering a step 2;
2. adjusting the phase angle of voltage and current of the transformer substation to be 0 degrees, detecting whether a reactive real-time value is 0 or not, and whether real-time values of other telemetering signals are corresponding full values or not, and if yes, entering step 3;
3. adjusting the phase angle of voltage and current of the transformer substation to 90 degrees, detecting whether an active real-time value is 0 or not, and whether other remote measurement real-time values are corresponding full values or not, and if so, entering a step 4;
4. adjusting the phase angle of voltage and current of the transformer substation to 210 degrees, and detecting whether the active real-time value is
If yes, entering step 5, if the reactive real-time value is (-1/2) full value, and if the three-phase current real-time value is full value;
5. and adjusting the full scale value of each telemetering signal, repeating the step 2-4, and when the step 2-4 meets the condition again, representing that the telemetering signal is verified to be passed, and sending a verification result of successful verification to the transformer substation.
Any step 1-4 does not meet the conditions, the telemetering signal verification failure is represented, and the verification result of the verification failure can be fed back to the substation.
It should be noted that the above-mentioned verification template is only an example of the embodiment of the present invention, and a person skilled in the art may select other telemetry signal combinations and other verification steps according to practical situations, and the embodiment of the present invention is not limited in this respect.
The method comprises the steps of receiving a debugging list information acquisition request of a preset interval sent by a transformer substation; analyzing the debugging list information acquisition request, and sending a target debugging list requested by the debugging list information acquisition request to the transformer substation; receiving a starting request sent by a transformer substation based on a target debugging list; analyzing the starting request to determine a target remote measuring point and a checking template, and acquiring a remote measuring signal of the target remote measuring point; and checking the telemetering signal based on the checking template to generate a checking result. Therefore, people do not need to check the remote measuring signals, the labor cost is reduced, and the checking efficiency is improved.
