基于半实物仿真技术的AVR通用动态测试系统设计

Design of the AVR General Dynamic Test System Based on HILS Technology

自动电压调节器（AVR）作为同步发电机控制系统的重要组成部分之一，其性能只有通过开环试验（输入输出特性、开环放大倍数等试验）和闭环测试实验（切负荷、短路、零起升压和静稳测试等试验）才能够被验证，而传统的工业现场测试、动模实验室测试以及RTDS测试等方法都有一定的局限性。本文结合现代自动测试技术、虚拟仪器技术以及Labwindows编程技术，设计了自动电压调节器半实物仿真测试系统，对于提高AVR测试性能、搭建通用测试系统平台均具有重要的意义。

By taking the automatic voltage regulator （AVR） as one of the important parts of synchronizing generator control system, its properties can be verified there is only by means of the open-loop experiments （including the inputoutput characteristics, open-loop gain experiments and so on） and the closed loop experiments （the experiments of load shedding, short-circuiting, voltage stepping-up and static/stable testing are included）, but the traditional test methods of the industrial site test, dynamic simulation labo- ratory test and RTDS test all are of the certain limitations. In this article, the AVR hardware-in-the-loop simulation test system is designed by combining the automatic testing technology with the virtual instrument technology and the Labwindows programming tech- nology, it has a great significance for enhancing the AVR testing performance and setting up the platform of general test system.
