Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Fig. 1 is a flowchart of a method of an embodiment of a power equipment locking method according to the present application, as shown in fig. 1, where fig. 1 includes:
101. and carrying out remote control operation on the remote equipment.
It should be noted that, in the present application, remote control operation is performed on a remote device in a power grid system, and whether to continue the remote control operation is determined by monitoring whether the remote device has an abnormal signal.
102. If an alarm signal meeting the locking alarm level appears during the current remote control operation, the current remote control operation is prompted to be abnormal, and the current remote control operation is interrupted.
It should be noted that, the present application can preset a classification rule for the alarm signal, and judge whether the acquired alarm signal satisfies the lockout alarm level by comparing the acquired alarm signal with the preset classification rule. Specifically, if an alarm signal appears around the remote device to be remotely controlled during the current remote control operation period and the alarm signal meets the locking alarm level, it is prompted that the current remote control operation is abnormal and the current remote control operation of the terminal is performed.
103. And if the alarm signal meeting the locking alarm level does not appear, continuing the current remote control operation.
It should be noted that, if no alarm signal appears around the remote device to be remotely controlled during the current remote control operation, or the alarm signal that appears does not satisfy the lock alarm level, the current remote control operation is continued until the remote control operation is completed.
According to the method and the device, the alarm signal near the remote control operation equipment is acquired, the alarm signal is analyzed, whether the alarm signal meets the blocking alarm level or not is judged, and when the equipment is monitored to have a fault, the current remote control operation can be interrupted, so that the automatic monitoring of the programmed remote control operation quality is realized.
The present application further provides another embodiment of a power device latching method, as shown in fig. 2, specifically including:
201. and carrying out remote control operation on the remote equipment.
It should be noted that, in the present application, remote control operation is performed on a remote device in a power grid system, and whether to continue the remote control operation is determined by monitoring whether the remote device has an abnormal signal.
202. And collecting the operation duration and the range of the operation equipment corresponding to the current remote control operation.
It should be noted that, the present application may access a power grid operation control system (the system collects and monitors the state of the power grid equipment, may control the power grid equipment, and has power grid load flow analysis and calculation capability) to collect an equipment alarm signal by establishing a message bus and a collection technology. Specifically, the information that can be collected includes: the operation duration corresponding to the current remote operation, the station of the remote operation, the position range of the remote operation equipment and the like. The system can receive the acquired information in real time and classify, analyze and perform topology operation on the information.
203. And collecting alarm signals within the operation duration and within the range of the operation equipment.
It should be noted that, in the present application, corresponding warning information may be acquired according to the operation duration corresponding to the remote control operation and the location information of the operated remote device. Specifically, the alarm information in the operation duration range of the current remote operation and the position range of the operated remote device can be collected. For example, if the remote control operation duration is 15 minutes, the alarm signal within a certain range preset around the remote control operated remote device is only collected within 15 minutes after the current remote control operation starting time point. The preset range can be calculated by remote equipment in topology, including the interval of the remote equipment and the interval of opposite side station equipment.
204. And classifying the alarm signal according to a preset signal grade decomposition rule.
It should be noted that, because some alarm signals do not greatly affect the safety of remote control operation, the collected alarm signals need to be processed in a hierarchical manner. Specifically, a signal analysis model may be established, including analyzing the characteristics corresponding to each alarm signal, and performing a hierarchical processing on the acquired alarm signals according to the characteristic information. When a series of characteristics of the alarm signal meet the locking condition, the alarm signal is judged to meet the locking alarm level, and the specific locking condition needs to be set in combination with the specific reality.
205. If an alarm signal meeting the locking alarm level appears during the current remote control operation, the current remote control operation is prompted to be abnormal, and the current remote control operation is interrupted.
It should be noted that when the acquired alarm signal meets the locking alarm level, the system may prompt that the current remote control operation is abnormal, and the continuous operation may cause an equipment failure.
206. And if the alarm signal meeting the locking alarm level does not appear, continuing the current remote control operation.
It should be noted that, when the acquired alarm signal does not satisfy the locking alarm level, that is, the system does not generate an abnormal prompt, the operator may continue the current remote control operation.
207. And if the alarm signal meets the locking grade, updating the monitoring state of the current remote equipment and generating an alarm signal history library.
It should be noted that, each time an alarm signal meeting the lockout level occurs during the remote control operation, the alarm signal history library during the remote control operation may be updated, so as to provide a basis for determining whether the next remote control operation is performed.
208. And verifying whether the alarm signal meeting the locking alarm level exists in the last remote control operation or not through the alarm signal history library, and if the alarm signal meeting the locking alarm level does not exist and the execution of the last remote control operation is finished, executing the current remote control operation.
It should be noted that, when the next remote control operation is to be performed, the alarm signal history library of the previous remote control operation needs to be determined. Specifically, if the end of the previous remote control operation time is not reached, waiting for the end of the previous remote control operation time, and enabling the current program to enter a waiting state; and after the last remote control operation time is finished, verifying the record in the alarm signal historical library, executing the next remote control operation if the record display result is normal, and interrupting the next remote control operation if the record display result is abnormal.
