According to the method for analyzing and calculating the strategy table of the stable 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 stable control device, so that the stable control device does not need to analyze the expression script of the strategy table during operation, instruction set data in the instruction set file can be directly operated, and the operation efficiency of the stable control device can be remarkably 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 working condition information before the power system fails and the actual failure data information.
Fig. 4 is a schematic diagram of an analysis flow of a policy table expression according to an embodiment of the present application.
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 piece by piece to obtain the expression script which can be identified by the embedded operating system.
S220, analyzing the expression script to obtain an instruction set in a binary instruction format which can be rapidly executed by the stable control device.
Wherein the expression script corresponds to a plurality of instructions in binary instruction format.
The logic expression and the mathematical expression obtained by configuration are translated one by one through a graphical model configuration tool, the generated expression script is in a data format which can be identified by an embedded implementation operating system, and the expression is analyzed into a binary instruction format which can be rapidly executed by the device.
Specifically, the binary instruction format instruction includes: an opcode, a source operand, a destination operand, and/or additional information. Wherein the characters of the opcode represent the type of operation 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 (when there is no additional information, the value is 0). The value of the opcode within an instruction represents the type of operation of the instruction. For example, "3" means "read model data to register"; "4" means "register write data model"; "6" means "two data addition"; "7" means "multiplication of two data".
Optionally, the characters of the operation code include: numbers and/or letters.
Expression scripts in the policy table, each script requiring splitting into multiple executable instructions. Taking a real-time data table as an example, the expression script "run.73=run.96×run.97+run.93" can parse and generate 6 executable instructions. As shown in table 1. "run" in the expression indicates a real-time data model table in the stability control device, the table number is 9, corresponding to the additional information in table 1.
TABLE 1
| Sequence number | Operation code | Source operands | 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 No. 9 table of the model table;
reading 97 th data of a No. 9 table of the model table;
multiplying two data;
reading 93 rd data of a No. 9 table in the model table;
adding the two data;
writing the calculation result into 73 rd data of the No. 9 table;
the operation flow of other instruction sets is similar to the instructions shown in table 1, and will not be described in detail.
After the binary file composed of the instruction sets is downloaded to the stability control device, the stability 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 texting script are processed in the integrated development environment, the device only needs to execute the instruction set, and the analysis flow of the control strategy expression script is skipped, so that the operation workload of the device is reduced, and the operation efficiency and the instantaneity of the device are improved.
