【摘要】：针对低电压穿越(LVRT)试验所需电压跌落发生器(VSG),提出一种基于LabVIEW上位机控制的变压器形式VSG设计方法。重点分析了所研制VSG实验平台的设计原理,通过LabVIEW设计上位机与本地VSG控制器进行通信控制,VSG控制器采用STM32F103作为主控芯片构建控制系统。VSG主体结构主要包括抽头变压器、继电器与限流电阻。研制的实验平台可实现上位机安全可靠操作VSG,能精确设置电压跌落持续时间,模拟不同跌落深度的电网故障电压,满足LVRT试验要求。实验结果表明所研制VSG实验平台的有效性与可靠性。
[Abstract]:In view of the voltage sag generator needed in low voltage traversing test, a design method of transformer type VSG based on LabVIEW upper computer control is proposed. The design principle of the developed VSG experimental platform is analyzed emphatically. The communication between the host computer and the local VSG controller is designed by LabVIEW. The main structure of the control system is composed of tap transformer. The main structure of the control system is constructed by using STM32F103 as the main control chip. Relay and current limiting resistance. The developed experimental platform can realize the safe and reliable operation of the upper computer, can accurately set the duration of voltage drop, simulate the power grid fault voltage with different drop depth, and meet the requirements of LVRT test. The experimental results show that the developed VSG experimental platform is effective and reliable.
