Description
Technical Field
The invention relates to the field of high-voltage direct-current transmission of a power system, in particular to a method and a device for importing a direct-current transmission automatic power plan.
Background
Direct current transmission power control (power control of DC transmission system) is a link of a direct current transmission control system for maintaining the power transmitted by a direct current system at a given value. And the control of the transmission power of the direct current transmission is realized by changing the current setting value of the direct current regulator. According to the adjustment of the operation mode of the power grid and the change of the load every day, the transmission power of the direct current transmission project in actual operation needs to be adjusted every day under the arrangement of a dispatching center, and the adjusted parameters are mainly power values needing to be transmitted at the specified time point.
The current power control has two operation control modes: one is manual control, power fixed value and power lifting speed are manually input by an operator; the other is automatic power control, the power fixed value is automatically changed according to the preset direct current transmission power (generally taking the day as a unit), and when the power adjusting points of each day reach a certain number, the computer sends the power fixed value according to the time points in the automatic control mode, so the workload of operators can be reduced.
In practical engineering, a computer receiving an automatic power plan file from a scheduling center is used as a production plan workstation, the production plan workstation sets the automatic power plan file to an automatic power plan setting workstation to be executed by a server, the two workstations are not allowed to be connected into a network due to safety requirements, therefore, in the automatic power plan setting process, after an operator receives an automatic power curve, two modes are transmitted from the production plan workstation to the automatic power plan setting workstation, the first mode is manual input after printing, the second mode is importing the file after recording the file to an optical disk (the U disk is forbidden due to safety requirements), and the second mode is less than the first mode in workload.
However, as the current load scheduling is increasingly accurate, multiple curve adjustments may occur on the day of scheduling, the automatic power curve needs to be re-set to the server and executed each time, although the process of receiving the curve by the production planning workstation is automatically obtained from the scheduling center, the production planning workstation does not have any prompt after receiving the automatic power plan file, needs to be manually checked and updated by an operator, and needs to frequently check whether a new curve is issued or not because the power adjustment is time-efficient, and needs to perform curve setting after receiving, which consumes a lot of manpower and time in the process.

Detailed Description
For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings and examples.
At present, the main principle of the method for implementing automatic power control is that an automatic power curve is set and then stored in a server, a corresponding power instruction is sent after a time point arrives, and in the automatic power control, besides a power setting value, a power slope value and an advance need to be calculated.
Fig. 1 is a flowchart of an existing automatic power control work, as shown in fig. 1, in an actual project, a computer that receives an automatic power plan file from a scheduling center is used as a production plan workstation, the production plan workstation sets the automatic power plan file to an automatic power plan setting workstation to be executed by a server, and the two workstations are not allowed to be connected to a network due to safety requirements.
The automatic power plan file is a daily power transmission plan corresponding to a direct current transmission project issued by a scheduling center, the file format is an Excel file, the content is a power transmission plan arranged according to time points, generally, one power point is every 15 minutes, and 96 power points are provided every day. The automatic power plan file in this embodiment may also be an automatic power curve.
And the production planning workstation is connected with the production planning system of the dispatching center and automatically receives an automatic power planning file (Excel format) issued from the dispatching center.
The automatic power plan setting work station is used for completing setting of an automatic power control execution sequence in the station according to the power plan requirement of a dispatching center and according to the time and the reference value of input target power and a power slope value in the adjusting process.
However, as the number of times of change of the daily scheduling plan increases, and because the production planning workstation and the automatic power plan setting workstation are not in the same network, setting of the automatic power curve requires an operator to manually print and set or write a file into an optical disc and then import the file, and the planning workstation does not have any prompt after receiving the automatic power curve, so that the problem of manual refreshing and checking is required. The present embodiment provides the following embodiments based on the method and apparatus for importing an automatic power plan for dc power transmission provided by the present invention.
Example 1:
fig. 2 is a flowchart of a method for importing an automatic power plan for dc power transmission, as shown in fig. 2, including:
the method comprises the following steps that S1, when a production plan workstation is detected to receive an automatic power plan file, the automatic power plan file is transmitted to an automatic power plan setting workstation through a reverse isolation device;
and S2, when the automatic power plan setting workstation receives the automatic power plan file, the automatic power plan file is imported.
The production planning workstation, the reverse isolation device and the automatic power planning setting workstation work in the same Local Area Network, the reverse isolation device is used for transmitting data (only a plain text file can be transmitted) to equipment located in a Local Area Network (LAN) under the condition of physical isolation of the LAN, the working mode of the reverse isolation device is set to be stored after transmission, and the existing SysKeeper-2000 can be used.
As shown in fig. 3, if the scheduling center sends an automatic power curve plan of a certain day, the file format is an Excel file, and the file is automatically transmitted to the production planning workstation of the converter station through the production planning system, the execution steps of the automatic power curve in the station are as follows:
1) Storing an automatic power plan file issued by a dispatching center in a first receiving directory pre-established in a production plan workstation;
2) Monitoring a first receiving directory on the production planning workstation and initiating a file format conversion when an updated automatic power plan file is detected;
3) Storing the automatic power plan file in a text format into a reverse isolation device transmission directory which is pre-established in a production plan workstation;
4) Scanning the transmission directory of the reverse isolation device uninterruptedly by the reverse isolation device, and automatically transmitting the file to a second receiving directory of the automatic power plan setting workstation when the transmission directory of the reverse isolation device is detected to be updated;
5) Carrying out new file detection on a second receiving directory of the automatic power plan setting workstation, and sending an event to notify an operator when detecting a file transmitted in the previous step;
6) The operator receiving the event notification imports the curve into the system after confirming that the file is correct through the original function or common means, and the system executes the curve according to the time point;
in the above process, except that the last step must be confirmed manually according to the rule, other steps are automatically completed, and manual intervention is not needed after configuration is completed.
The process of manual participation comprises the following steps: when an event is prompted, judging whether an automatic power plan file in an automatic power plan setting workstation is consistent with an automatic power plan file sent by a dispatching center and received by a production plan workstation;
when the data in the two automatic power plan files are consistent, the automatic power plan file received on the automatic power plan setting workstation is imported into a server; otherwise, inputting an automatic power plan file sent by the dispatching center and received by the production plan workstation and importing the automatic power plan file into the server.
The embodiment also provides that the server issues the planned power in the automatic power plan file to the host for execution according to the set time, simultaneously monitors the actual power of the host during execution, and prompts in an event mode when the error between the actual power of the execution and the planned power exceeds the threshold.
The event mode prompting method provided in this embodiment includes: set prompts and sounds.

When the dispatching center sends the automatic power plan file, the production plan workstation obtains the automatic power plan file, stores the automatic power plan file in the first receiving directory, reads the file content and converts the file content into a text format file, checks the file generated by automatic conversion, and compares whether the file content is consistent with the file content:
FIG. 5 is the original document data of the dispatching center, and FIG. 6 is the converted document data of the original document data of the dispatching center;
when the file sent by the scheduling center is updated, fig. 7 is the original file data of the scheduling center (the first row has adjustment), and fig. 8 is the converted file data (the first row has adjustment);
as can be seen from fig. 5-8, when it is detected that an updated automatic power plan file is located in the first receiving directory of the production planning workstation (according to the receiving directory configuration of the actual planning system), the conversion procedure performs automatic conversion, and the converted data content has no error, and the file generated after conversion is automatically transferred to the transmission directory of the reverse isolation device.
Two tasks are configured in a reverse isolation device, files are transmitted from a production plan workstation to two automatic power setting workstations, and the transmission type is selected to be reserved after transmission;
the text files generated by the automatic power conversion in fig. 5-8 are checked for the transmitted files in the designated directories (the second receiving directory in this embodiment) of the two automatic power setting workstations;
regenerating the auto power file through fig. 5-8, checking for file updates in the designated directories of the two auto power tuning workstations;
experiments prove that the transmission type of the reverse isolation device is modified to be reserved after transmission, one file in the production plan workstation can be simultaneously transmitted to the two automatic power setting workstations through the reverse isolation device, and the file can be automatically updated to the automatic power setting workstations after being regenerated.
As shown in fig. 9, the file is transmitted to a specified directory in the automatic power plan tuning workstation through the reverse isolation device, and is prompted to be automatically imported into an automatic power curve data list display dialog box;
as shown in fig. 10, the automatic power curve data imported from the text file generated in fig. 6;
as shown in fig. 11, an automatic power curve is generated from the automatic power curve data in fig. 10.
Fig. 9-11 demonstrate that the converted file, after being transmitted to the automatic power plan tuning workstation via the reverse isolation device, can be directly imported into the automatic power curve module, with the imported data being consistent with the power points in the original file.
As shown in fig. 12, when an automatically converted automatic power plan file is transmitted to the automatic power plan setting workstation through the reverse isolation device, an event is sent to prompt an operator; and when the error between the actual power and the planned power exceeds a set value, an event is sent to prompt an operator.
