静止无功发生器信号调理电路的设计
资料介绍
设计了静止无功发生器（SVG）装置的信号调理电路。该电路对互感器采集的电压和电流信号进行处理,使之成为满足ADC端口电压要求的交流小信号。详细介绍了信号采集、过电压保护、低通滤波、方波发生、加减运算等电路的设计原理。利用Multisim10.0对SVG信号调理电路进行仿真,结果表明：调理电路达到输出电压0～3.6V范围的预期指标,能够用于SVG装置现场的信号采集。
A signal modulating circuit for static var generator（SVG） is designed,which processes voltage and current signals collected by transformer.The design principles are described in detail including signal collection,over-voltage protection,low-pass filtering,square wave generating,addition and subtraction etc.MultisimlO.0 is used to simulate the signal modulating circuit on SVG.The result shows that the signal modulating circuit can be used in signal collection of SVG device,and achieves expected targets that output voltage is 0 to 3.6 V.
