Medium and low-voltage power distribution network simulation system based on energy feedback

The invention discloses a medium and low-voltage power distribution network simulation system based on energy feedback. The medium and low-voltage power distribution network simulation system comprises an input incoming cabinet, wherein the input incoming cabinet is connected with a boosting transformer through a lead; the boosting transformer is connected with a high-voltage gauge table through a lead; the high-voltage gauge table is connected with a first cable simulation device through a lead; first cable simulation device is connected with a step-down transformer through a lead; the step-down transformer is connected with a second cable simulation device through a lead; the second cable simulation device is connected with a low-voltage outgoing cabinet through a lead; the low-voltage outgoing cabinet is connected with an electronic load through a lead; the electronic load is connected with an isolation transformer through a lead. The problems that no special real-time energy efficiency monitoring system capable of saving energy and reducing consumption is provided in the prior art, an RLC impedance load box is frequently adopted to load in a manner of energy consumption discharge in an electric equipment experiment, so as to cause low test accuracy, serious electric energy waste, and relatively low power, load cannot easily meet the continuous adjustment capacity in different work conditions, and an apparatus is easily aged and burnt, and is poor in thermal stability and single in load form are solved.
