Controllable electric reactor based low-voltage ride through system and test method thereof

The invention relates to a controllable electric reactor based low-voltage ride through system and a test method thereof. The controllable electric reactor based low-voltage ride through system comprises a low-voltage ride through test component comprising a controllable electric reactor, and a first current and voltage detection component and a second current and voltage detection component are arranged at two ends of the low-voltage ride through test component respectively. The controllable electric reactor based low-voltage ride through system further comprises an upper computer and a control trigger module, wherein the control trigger module is connected with the upper computer through a power transmitter and further connected with the low-voltage ride through test component. The controllable electric reactor based low-voltage ride through system has the advantages that firstly, 90%-0% voltage class of voltage drop at a test point can be realized, and 1% drop and recovery precision can be met; and secondl
