Description

Substation site table generation and checking method

Technical Field

The invention relates to the technical field of power automation, in particular to a power transformation station table generating and checking method.

Background

The point table is an information point table and comprises names, definitions and an order list of remote measuring/remote signaling collected by various devices in the transformer substation, and names, definitions and an order list of remote control defined for operating devices. The former is often referred to as a "telemetry (telemetry)" point table, and the latter is often referred to as a "telemetry" point table. The point table is typically provided by a technician at the substation automation system manufacturer. In theory, the point table of the IEC61850 substation is self-describing, and in engineering practice, is converted into a traditional point table. A complete and standard-describing point table has important significance for master station side scheduling automation and other systems. The current point table still has some defects, and is highlighted in the following two aspects:

(1) the points are incomplete, and some points are collected but not collected;

(2) the dot description is not canonical.

TABLE 1 Equipment sheet (example)

Numbering	Description of the invention	Type of device	Voltage class
				1	10kV east line 701 switch	Circuit switch	10kV
2	1# main transformer high-voltage side 2201 switch	Main transformer switch	220kV
				3	……	……	……

2. Obtaining a list of substation devices (the data may be from a device manufacturer or an existing database)

1) And (4) completing the equipment list supplement, including the number, the equipment description, the equipment type and the voltage grade. Wherein "device type"

Can and can only come from the template, i.e. normalized;

2) and submitting the equipment list.

3. Typical monitoring information table

(1) On the basis of the equipment list, the equipment type check is finished (the existing software provided by the main station manufacturer can be utilized);

(2) the device description validation is done with two jobs:

first, detecting out-of-compliance descriptions (available with existing software provided by the Master station vendor);

secondly, the positive unconventional description is modified;

4. generating a point table by taking the equipment list as input; taking telemetry and telemetry as an example, the generation of the point table is shown in tables 2 and 3 below:

TABLE 2 typical monitoring information Table (remote signaling example)

TABLE 3 typical monitoring information Table (telemetry example)

5. Canonical point table generation

The point table is confirmed and generated by the integrated equipment provider:

(1) as shown in tables 2 and 3, each point is filled with a collection point number (coefficient, remote control number). Determining points which cannot be acquired, wherein the number of the acquired points is null;

(2) appending and explicitly identifying points not specified in a typical monitoring information template;

(3) the point table submission is automated;

(4) checking the validity of the point table by using software provided by a main station manufacturer; the operation is mainly performed by automatic operation and maintenance personnel of a power transformation management station and a system operation part of a power supply bureau, the power transformation management station is the automatic operation and maintenance personnel of a plant station, the system operation part is the automatic operation and maintenance personnel of a main station, and various telemetering and remote signaling of the plant station are remotely transmitted to the main station.

(5) Automatically submitting the new acquisition point type to regulation and control professional examination and confirmation, and adding a template if necessary;

(6) and automatically sending the order form to the master station manufacturer.

Example two

The stock point table checks the stock substation to standardize the point description (taking remote signaling as an example below), and prompts the point of missed mining.

1. The equipment is shown in table 4:

TABLE 4 Equipment sheet

Numbering	Description of the invention	Type (B)	Description of the Specification (second)	Device ID
					1	10kV east line 701 switch	10kV line switch	9726
2	1# main transformer high-voltage side 2201 switch	Main transformer 35kV side switch		1978
					3	……	……

2. Automatically providing a substation equipment list:

1) and filling a device list, including the number, the device description, the device type and the device ID. The device description may be derived from the master station.

2) When the equipment list is automatically prepared, the specification description is filled.

3. A typical telecommand table is generated as shown in table 5:

TABLE 5 typical Telecommunications watch

The master station manufacturer takes the equipment list and generates a typical telecommand table:

1) confirming an applicable transformer substation typical monitoring information template based on the transformer substation voltage grade;

2) and taking the equipment list as input, and automatically generating a typical remote signaling table by using software.

EXAMPLE III

In step S3, when the inventory substation cannot modify the primary site description, a second description is required; the point may be automatically associated with the second description or manually associated.

1. The second description association is a process of establishing a corresponding relationship between the second description and the point ID, and the input result is as shown in table 6 below.

Table 6 second description association table

2. Exporting a telecommand table: the raw number scale derived from the master station for the corresponding plant is shown in the following table:

TABLE 7 original telecommand table

3. Configuring keywords

With the use of the template, a key is configured for a typical numerical quantity of each device. One typical keyword example is as follows:

4. automatic association

Automatic association is the use of a program to complete the association.

5. Artificial association

And for the point of failure of automatic association, providing unmatched remote signaling columns and standard description columns, and realizing concise manual association.

One specific example is shown in tables 8 and 9, where manual association is easily achieved by comparing the upper and lower columns. With the description of table 9, table 8 is filled with the relevant second description.

TABLE 8

Device ID	Point ID	Description of points	Second description
				9726	4580	10kV east return control short wire
9726	4581	10kV east spring-controlled spring energy
				9726	4582	Oriental SF6 low 10kV

Device ID	Second description
		9726	Disconnection of switch control loop of 10kV east line 701
9726	10kV east 701 switch spring non-stored energy
		9726	10kV east line 701 switch SF6 low alarm

6. Import second description

And automatically importing a second description of the plant station, and returning remote signaling without the second description. For the remote signaling not configured with the second description, it may be configured as a matter, and the alarm is not generated any more. The automatic association or manual association work is completed off line, and the step is to lead in the operation system to really take effect and play a role.

In addition, in step S2, when the rule is set, the specification of the first level selection voltage class, the second level selection device, and the third level configuration point describes the rule and whether the set point is selectable or not is possible.

1) based on national, industrial and enterprise specifications, compiling typical point table templates for the transformer substations of all voltage levels;

2) designing a point table rule configurator according to the voltage grades and the equipment types based on the typical point table templates of the transformer substations of the voltage grades to form a point table generation and checking rule base;

3) newly building a transformer substation, and forming a standard and complete point table by using rules;

4) and the stock transformer substation realizes point table description standardization and integrity check by using rules.
