Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] Such as Figure 5 As shown, a sensitivity analysis method of aircraft power supply system based on dq transformation, the steps are as follows:
[0024] Step 1) Transform the AC power generation system, inverter, DC part, control link, load, and line in the aircraft power supply system by using the dq transformation theory, and simplify and analyze the circuit by equivalent parameters.
[0025] In a circuit structure containing an alternator and an AC load, it is necessary to establish an equivalent circuit through dq transformation and dq inverse transformation. After transformation according to the formula, assuming that the q-axis circuit input is 0, only the d-axis equivalent circuit needs to be considered to obtain:
[0026] dq tran...
