Description

technical field [0001] The invention relates to the field of electric power, in particular to an experimental device and method for a high-voltage level voltage drop compensation device. Background technique [0002] Voltage sag refers to a phenomenon in which the voltage amplitude drops to 10% to 90% of the rated voltage amplitude, and the duration is half a cycle to several seconds. Most of the voltage dips are caused by factors such as short-circuit faults in transmission and distribution lines, induction motor startup, etc. Voltage drop is an objective existence that is difficult to predict and cannot be avoided. In important users such as the information industry, the military, and hospitals that use microprocessors or computers, every voltage drop may cause huge economic losses or political influences. [0003] Dynamic Voltage Restorer (DVR) is an economical and effective device to solve the voltage sag problem. In order to verify the effectiveness of the voltage dr...
