【摘要】：針對低電壓穿越(LVRT)試驗所需電壓跌落發(fā)生器(VSG),提出一種基于LabVIEW上位機控制的變壓器形式VSG設(shè)計方法。重點分析了所研制VSG實驗平臺的設(shè)計原理,通過LabVIEW設(shè)計上位機與本地VSG控制器進(jìn)行通信控制,VSG控制器采用STM32F103作為主控芯片構(gòu)建控制系統(tǒng)。VSG主體結(jié)構(gòu)主要包括抽頭變壓器、繼電器與限流電阻。研制的實驗平臺可實現(xiàn)上位機安全可靠操作VSG,能精確設(shè)置電壓跌落持續(xù)時間,模擬不同跌落深度的電網(wǎng)故障電壓,滿足LVRT試驗要求。實驗結(jié)果表明所研制VSG實驗平臺的有效性與可靠性。
[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.
