The invention relates to the technical field of power supply
experiment control, and discloses a test control method of a variable-frequency power supply, comprising the following steps: S1, generating a dynamic change
signal of at least one load type through dynamic load
simulation, the load type including resistive, inductive or capacitive; s2, acquiring original signals of output
voltage, current and frequency parameters of the variable-frequency power supply in real time; s3, according to preset test condition parameters, a control instruction of the variable-frequency power supply is adjusted, and the control instruction comprises an output
voltage amplitude, a frequency and a
phase angle; s4, in the test process; and S5, generating the waveform containing the
voltage. Through flexible switching and dynamic disturbance
simulation of resistive, inductive and capacitive loads, complex working conditions of extreme transient, periodic fluctuation and random disturbance in an industrial scene are reproduced, and the anti-interference capability and stability of the variable-frequency power supply under the dynamic load are comprehensively verified in combination with a multi-mode load change strategy. And the test coverage and the scene restoration precision are obviously improved.
