摘要：

摘要：自动电压控制（ＡＶＣ）系统中各类算术运算、逻辑运算功能一般通过源代码或运算脚本实现，不利于标准化、模块化工程实施。开发了一套图形化组态软件，采用ＱｔＰｌｕｇｉｎ进行架构设计和规约开发，使图形平台和通信规约的扩展、升级与维护变得容易；以图形化组态的方式，实现了ＡＶＣ中的算术运算、逻辑运算、机组所属控制域拓扑计算、虚规约与实际规约数据交互功能。实际运用表明，可有效提高工程实施效率。

Abstract:

Abstract:Mathematical calculations,logic calculations,and other functions are generally realized through the source codes or calculated scripts for automatic voltage control(AVC)system,which is not conducive to standardization and modular implementation for engineering.The Qt Plugin was used for design and protocols development,so that it becomes easy to be extended,upgraded and maintained for the graphics
and communication protocols.Arithmetic operations,logic operations,the calculation of control domain and the interaction between virtual protocols and actual protocols were realized through graphical configurations.Finally,it was real world applications, which improved the efficiency of the project.
