Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the patent;
for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product;
it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
First, the terms of art related to the present invention will be explained:
remote signaling: telecommand is the amount of opening of dynamic data, abbreviated as YX. The method is used for remotely transmitting the equipment state information of a monitored plant station to a dispatching station, such as the states of a plant, a station-side switch (breaker), a disconnecting link and the like.
SOE: and (4) recording the sequence of events, recording the actual time and state of occurrence of the remote signaling, and the time resolution is millisecond level.
COS: event deflection records refer to telesignalling deflection records received by an EMS master station.
Telemetry: telemetry is a remote measurement, abbreviated YC. The method is characterized in that main analog parameter variables of a monitored plant station are remotely transmitted to a dispatching station, such as power, voltage, current and the like of the plant and the station.
The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
Example 1:
the embodiment provides a method for verifying relevance of a scheduling automation information point. As shown in fig. 1, the method comprises the steps of:
s1: determining the type of the information point to be subjected to correlation verification, and if the information point is subjected to correlation verification of the remote signaling point, executing S2; if the correlation check is the telemetry point correlation check, executing S3;
s2: and checking remote signaling point association.
The correlation check of the remote signaling mainly refers to that a group of remote signaling signals start to act simultaneously or according to a time sequence, and debugging software automatically judges the reasonability of the action sequence of the signals. The remote signaling point association check is based on a set action sequence, so that a user can define an association rule, and summarize operation experience in practical application and add the operation experience at any time.
The specific method comprises the following steps:
and the master station debugging personnel automatically debugs the software at the dispatching end to generate a debugging work order, adds one or more remote signaling associated debugging records in the work order, and sets the action logic of the signals into the associated debugging records.
Action logic includes a plurality of signals and their number and order of actions.
When debugging, a field debugging person starts associated debugging, then the fault is simulated according to the real condition, the automation terminal generates a telecontrol signal according to the condition when the actual fault occurs, and the telecontrol signal is sent to the monitoring background and the dispatching terminal. And the automatic debugging software of the dispatching end is matched with the preset logic after receiving the signals, and all the signals contained in the associated debugging record are synchronously debugged after the signals are successfully received.
For example, a transmission test verification logic of a reclosing of a switch protection belt is as follows:
the master station system automatically judges that the signals are complete and the time sequence is correct, then the test is successful, the system automatically records the debugging success information, and meanwhile, all the signals generated in the test also record the debugging success information in the remote signaling table.
The definition method of the remote signaling point association check rule is as follows:
signal attributes are defined by differentiating between the ways in which key or attribute fields are described.
And secondly, the judgment rule is based on remote signaling points at the same interval, and all the remote signaling points are contained in a debugging form.
And thirdly, the verification rule is defined in a time sequence mode, remote signaling in the same interval occurs in a preset time sequence (the time sequence takes SOE time as the standard), and the whole set of remote signaling is debugged and passed after the matching is successful.
Judging the SOE time sequence of the signals and simultaneously judging that both the SOE and the COS of each signal in the group send signals; when the delayed signal judges the COS alarm, the delay is considered (the signal of which the signal generation time does not reach the delay does not generate the COS).
There may be one or more remote signaling association check rules for each type of interval.
S3: and (5) remote measuring point correlation verification.
The correlation verification of the remote measuring points mainly means that remote measuring values (such as current, active power and reactive power at the same outlet interval or three-phase voltage and three-line voltage of the same bus) of a plurality of remote measuring points on the same equipment are changed according to a set rule at the same time, and debugging software automatically judges the reasonability and correctness of the change of the values of the remote measuring points.
The specific method comprises the following steps:
and the master station debugging personnel automatically debugs the software at the dispatching end to generate a debugging work order, one or more remote measuring associated debugging records are added in the work order, and the change logic of the remote measuring values is set into the associated debugging records.
When debugging, a field debugging person starts associated debugging, and then the remote measuring value is simulated according to the real situation, and the automation terminal can upload the remote measuring value to the monitoring background and the dispatching terminal. And the automatic debugging software of the dispatching end matches the received remote measuring value with preset logic, and all the remote measuring signals contained in the associated debugging record are synchronously debugged and finished after the remote measuring values are successfully matched with the preset logic.
For example, 110kV line switch telemetry test verification logic:
and the master station automatically judges that the telemetering values in all the steps change according to the set logic, and then judges that the test is successful, and the system automatically records the debugging success information.
The definition method of the telemetry point association check rule is as follows:
firstly, full scale values of all remote measuring points are defined, namely the maximum value of measurement collection.
Define verification rules according to electrical relationships between the telemetry measurements, for example: power is current voltage 1.732, line voltage is phase voltage 1.732, etc.
And thirdly, defining a telemetering value change rule according to the sequence of field addition, wherein the addition value is expressed by the fraction of a full scale value, and other changes (such as angles) are added according to actual requirements.
And fourthly, if the remote measurement package changes the three-phase electrical quantity, adding test contents for distinguishing the three phases (adding different values to the three phases) to prevent phase sequence errors.
There may be one or more telemetry association check rules for each type of interval.
The terms describing positional relationships in the drawings are for illustrative purposes only and are not to be construed as limiting the patent;
it should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
