Description

Automatic auditing method for first work ticket safety measures of line

Technical Field

The invention belongs to the technical field of power dispatching automation, and particularly relates to an automatic auditing method for a first work ticket safety measure of a circuit.

Background

The work ticket is an organizational written form control basis designed for safe and orderly implementation of production operations such as power generation, power transmission, power transformation, power distribution, scheduling and the like of a power grid. According to the relevant regulations of the southern power grid company, workers must use work tickets when performing relevant work. Since the first work ticket of the line relates to the line power failure operation, and generally relates to the operation of two or more stations, the power dispatcher needs to be responsible for checking the first work ticket of the line and allowing the line to work. The first work ticket of the auditing line comprises auditing of personnel qualification, planned work time, power failure line name, work content, work section, safety technical measures and the like, and the safety technical measures are important contents of the work ticket, relate to items such as relevant switches, disconnecting links, grounding wire positions and the like, and are directly related to the safe operation of a power grid and even the personal safety of constructors. The power dispatcher needs to repeatedly and carefully verify whether the listed safety technical measures are complete or not and whether omission, errors and the like occur or not, so that the link occupies most of the time for the power dispatcher to examine the work ticket, and the work efficiency of the power dispatcher is seriously reduced.

As shown in fig. 4, the name of the blackout line related to the first work ticket of the line is 110kV sheng lake line, in step S1, the transformer substation at the head end of the line is 220kV sheng sha station, and the transformer substation at the tail end of the line is 110kV pond lake station, and in step S1, the device set of blackout line intervals generated according to the CIM power grid data model, that is, the device set of the blackout line intervals is generated according to the CIM power grid data model

The 220kV saint sand station 110kV saint lake line spacing device set is {110kV 1M bus, 110kV 2M bus, 110kV 3M bus, 1212 switch, 12121 knife switch, 12122 knife switch, 12123 knife switch, 12124 knife switch, 1212B0 grounding knife switch, 1212C0 grounding knife switch, 121240 grounding knife switch };

110kV lake station 110kV saint lake line spacing device set ═ {110kV 1M bus, 1212 switches, 12121 knife switch, 12124 knife switch, 1212B0 grounded knife switch, 1212C0 grounded knife switch, 121240 grounded knife switch }.

As shown in fig. 4, in step S2, three basic description word sets and three special character sets are respectively generated according to the description requirements of the equipment set and the three column descriptions of the safety measures, according to the first and the last substations of the line:

(1) a basic description word set and a special character set generated according to the first column description requirement of the safety measure, namely

The 220kV Saint station side basic description word set FB1 and the special character set FS1 are respectively

FB1 ═ break, saint sand station, 110kV saint lake line, 1212 switch, pull, line side 12124 knife switch, 1M side 12121 knife switch, 2M side 12122 knife switch, 3M side 12123 knife switch, take down, secondary fuse of line side voltage transformer, or break, air switch };

FS1 ═ q, 220kV, quadratic, and, ": ",", ","; ",",",",",",",". "};

the 110kV pond lake station side basic description word set TB1 and the special character set TS1 are respectively

TB1 ═ disconnect, pond lake station, 110kV saint lake line, 1212 switch, pull, line side 12124 knife switch, 1M side 12121 knife switch, take down, secondary fuse of line side voltage transformer, or disconnect, air switch };

TS1 ═ q, 110kV, quadratic, and, ": ",", ","; ",",",",",",",". "};

(2) the basic description word set and the special character set generated according to the second column description requirement of the safety measure, namely the 220kV Saint station side basic description word set FB2 and the special character set FS2 are respectively as follows:

FB2 ═ on, saint sand station, 110kV saint lake line, line side 121240 earthing knife switch };

FS2 ═ q, 220kV, ": ",", "; ",",",". "}

The 110kV pond lake station side basic description word set TB2 and the special character set TS2 are respectively

TB2 ═ on, pond and lake station, 110kV saint lake line, line side 121240 earthing knife switch };

TS2 ═ { ough, 110kV, ": ",", "; ",",",". "};

(3) the basic description word set and the special character set generated according to the third column description requirement of the safety measure, namely the 220kV saint sand station side basic description word set FB3 and the special character set FS3 are respectively as follows:

FB3 ═ 5 { at, saint sand station, 110kV saint lake line, line side 12124 knife switch, 3M side 12123 knife switch, operating handle, line side voltage transformer, secondary fuse or, air switch, hang, prohibit closing, line is worked by person, signboard };

FS3 ═ q, 220kV, quadratic, and, up, over, where, ": ",", ","; ",",",",",",",". ",", ","! "};

the 110kV pond lake station side basic description word set TB3 and the special character set TS3 are respectively

TB3 ═ TB3 { at, pond and lake station, 110kV saint lake line, line side 12124 knife gate, operating handle, line side voltage transformer, secondary fuse or, air switch, on hook, no switch, line working by human, sign };

TS3 ═ q, { true, 110kV, quadratic, and, up, suspended, where, ": ",", ","; ",",",",",",",". ",", ","! "};

in step S3, all characters in the security measure descriptive sentence are marked as invalid, and in subsequent steps S4 and S5, all elements in the generated basic descriptive word set and special character set are determined one by one, and characters determined to be valid are marked as valid, and characters determined to be invalid or characters not belonging to the basic descriptive word set and special character set are continuously kept as invalid.

As shown in fig. 2, in the step S41, when checking the first column, the second column, and the third column of the safety measure, the corresponding basic description word sets are respectively selected as FB1, TB1, FB2, TB2, FB3, and TB3 according to the first-end substation and the last-end substation of the line.

In step S42, a position information set including position information of each basic description word in the selected basic description word set is generated, and if not, the position information is null.

In step S43, if the basic description word position information is not null, it exists.

In step S44, when determining whether each basic description word satisfies the relative position constraint condition, the first column, the second column, and the third column of the checked safety measure are determined according to the relative position constraint conditions of each basic description word given in table 1, table 2, and table 3, respectively.

TABLE 1 safety action first column each basic description words relative position constraint

TABLE 2 second column of Security measures each basic description word relative position constraint

TABLE 3 third column of Security measures each basic description word relative position constraint

As shown in fig. 4, in step S5, the special characters (including general special words and punctuation marks) do not affect the correctness of the security description sentence in some cases, but if they exist, it is necessary to determine whether the existing position is reasonable. For example, in the first column of safety measures, the statement "open 110kV san lake line 1212 switch" is legal, while it is also legal to write that "should open 110kV san lake line 1212 switch", but it is illegal if "should" be written after "open". Similar problems exist for punctuation marks. Therefore, such special characters must be searched one by one and judged whether or not they are legal.

As shown in fig. 3, in step S51, when checking the first column, the second column, and the third column of the safety measure, the corresponding special character sets are selected as FS1, TS1, FS2, TS2, FS3, and TS3 according to the first-end substation and the last-end substation of the line, respectively.

In step S52, the security statements in the first, second and third column description are searched one by one to find whether each special character in the corresponding special character sets FS1 and TS1, FS2 and TS2, FS3 and TS3 exists, and if not, the next special character in the sets is searched.

In step S53, when it is determined whether the existing special character satisfies the relative position constraint condition, the first column, the second column, and the third column are determined according to the relative position constraint conditions of the special characters given in tables 4, 5, and 6, respectively, according to the checked security measures, and if not, the corresponding prompt information is generated.

TABLE 4 constraint conditions for relative positions of special characters in the first column of security measures
