Description

technical field [0001] The invention belongs to the field of aviation electrical systems, and in particular relates to an energy feedback type aircraft electrical load simulation method and device including a load simulator and a grid-connected inverter. Background technique [0002] At present, one type of aircraft electrical analog load is a resistive load, which is not only inconvenient to adjust, but also difficult to control accurately. The size and parameters of the load will change with the change of the load and the ambient temperature, and cause a large amount of electrical energy to be converted into heat and lost. Coupled with the required cooling equipment, it not only requires extra space, but also requires additional operating costs, and will cause noise pollution to the environment. With the advancement of research on wide-body aircraft and more electric aircraft, the number and types of aircraft electrical loads have increased by an order of magnitude compare...
