Secondary Development Method of Control Program for Excitation Regulator of Synchronous Generator

Abstract

The invention discloses a secondary development method of a synchronous generator excitation regulator control program integrated embedded language, comprising the steps as follows: (1) compiling an embedded script program using lua scripting language; (2) modifying the running environment program of the script program according to an operating system and a compiler used so as to link the running environment of the script program to a host program in the form of program library, wherein the host program is an excitation regulator C language control program; (3) writing an interface function for calling the script program from the host program and an interface function for accessing the host program from the script program; and (4) initializing the running environment and the running state of the script program, and completing registration of the interface function for calling the script program from the host program in the host program so as to enable the host program to read, compile and execute the script program by calling the interface function of the script program.

Description

technical field [0001] The present invention relates to a method for realizing the control program of a synchronous generator excitation regulator, specifically, it relates to a synchronous generator excitation regulator control program integrated and embedded with short development period, strong expansion capability, low maintenance cost and relatively independent operation The secondary development method of formula language. Background technique [0002] The existing excitation regulator control program is generally developed directly on the real-time operating system, or using configuration software and PLC to develop. Although the technical difficulty of using configuration software and PLC is low and the development and testing period is short, the disadvantages are also obvious. The disadvantage is that it is not flexible enough and the development has limitations; while the control program developed directly on the real-time operating system is flexible in design an...

Problems solved by technology

Although the technical difficulty of using configuration software and PLC is low and the development and testing period is short, the disadvantages are also obvious. The disadvantage is that it is not flexible enough and the development has limitations; while the control program developed directly on the real-time operating system is flexible in design and easy to use. Convenient, but the disadvantage is that programming is more difficult than configuration and PLC development, and changes in project requirements require re-development of branch programs

The applications developed by the above three methods are not scalable to changes in project requirements, and need to be re-modified, tested, and downloaded if a small amount of modification, addition, or deletion of part of the signal state, calculation method, or control logic is required. The important thing is that if the control program of the main line version is upgraded, the control programs of each branch version need to be merged one by one to test the upgrade, which will bring trouble to the program version management, and the cost of program maintenance will increase with the branch version of the program. increasing and increasing
