Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Fig. 2 is a flowchart of a method for analyzing and calculating a policy table of a stable control device according to an embodiment of the present invention.
FIG. 3 is a schematic diagram of a control architecture of a stable control device according to an embodiment of the present invention
Referring to fig. 2 and fig. 3, a first aspect of the embodiments of the present invention provides a method for analyzing and calculating a policy table of a stability control device, including the following steps:
and S100, generating a calculation file of a strategy table according to the fault information of the power system.
And S200, analyzing the calculation file to obtain an instruction set file.
And S300, the instruction set file is sent to the stable control device in advance, and the instruction set data of the instruction set file can be directly read and operated when the stable control device operates.
According to the strategy table analyzing and calculating method for the stability control device, the logic calculation expression and the mathematical calculation expression of the strategy table are analyzed into the instruction set file and are preset in the stability control device, so that the stability control device does not need to analyze the expression script of the strategy table during operation, the instruction set data in the instruction set file is directly operated, and the operation efficiency of the stability control device can be obviously improved.
Specifically, in step S100, the step of generating the calculation file of the policy table according to the power system fault information may specifically be:
and generating a logic calculation expression and a mathematical calculation expression of the strategy table by using a visual model configuration tool according to the pre-fault working condition information and the actual fault data information of the power system.
Fig. 4 is a schematic diagram illustrating a parsing flow of a policy table expression according to an embodiment of the present invention.
Specifically, referring to fig. 4, in step S200, the step of parsing the calculation file to obtain the instruction set file may specifically include:
s210, translating the calculation files in the calculation files one by one to obtain an expression script which can be identified by the embedded operating system.
And S220, analyzing the expression script to obtain an instruction set in a binary instruction format which can be quickly executed by the stable control device.
The expression script corresponds to a plurality of instructions in a binary instruction format.
And the logic expression and the mathematical expression obtained by configuration are translated one by one through a graphical model configuration tool to generate an expression script which is in a data format which can be identified by an embedded implementation operating system, and then the expression is analyzed into a binary instruction format which can be quickly executed by the device.
Specifically, the instructions in binary instruction format include: an opcode, a source operand, a destination operand, and/or additional information. Wherein the character of the operation code indicates the operation type of the instruction.
The binary instruction generated by the text script adopts a custom format. Each instruction contains four parts: 1) an operation code; 2) a source operand; 3) a destination operand; 4) additional information (value 0 when no additional information is present). The value of the opcode within an instruction represents the operation type of the instruction. For example, "3" means "read model data to register"; "4" represents a "register write data pattern"; "6" means "two data are added"; "7" means "two data are multiplied".
Optionally, the characters of the operation code include: numbers and/or letters.
And each script needs to be split into a plurality of executable instructions. Taking the real-time data table as an example, the expression script "run.73 ═ run.96 ═ run.97+ run.93" may be parsed to generate 6 executable instructions. As shown in table 1. "run" in the expression represents the real-time data model table in the stability control device, with the table number 9, corresponding to the additional information in table 1.
TABLE 1
| Serial number | Operation code | Source operand | Destination operand | Additional information |
| 1 | 3 | 96 | 0 | 9 |
| 2 | 3 | 97 | 1 | 9 |
| 3 | 7 | 1 | 0 | 0 |
| 4 | 3 | 93 | 1 | 9 |
| 5 | 6 | 1 | 0 | 0 |
| 6 | 4 | 73 | 0 | 9 |
The instruction set shown in table 1 runs on the device as follows:
reading 96 th data of a 9 th table of the model table;
reading the 97 th data of the 9 th table of the model table;
multiplying the two data;
reading the 93 th data of the 9 th table in the model table;
adding the two data;
writing the calculation result into 73 th data of a 9 th table;
the operation flows of other instruction sets are similar to the instructions shown in table 1, and are not described in detail.
After the binary file composed of the instruction set is downloaded to the stabilization control device, the stabilization control device reads the custom instruction stream in the binary file in real time, and sequentially executes the instructions to obtain the execution result of the policy table. Because the text analysis and the data analysis of the text script are processed in the integrated development environment, the device only needs to execute an instruction set, and skips the analysis flow of the control strategy expression script, so the operation workload of the device is reduced, and the operation efficiency and the real-time performance of the device are improved.

Specifically, the generating module 1 generates a logic calculation expression and a mathematical calculation expression of the policy table by using a visual model configuration tool according to the pre-fault condition information and the actual fault data information of the power system.
