The application discloses an adaptive regulation method and device for DC transient step source signals. A DC transient step low-voltage signal obtained by signal processing is corrected by using a closed-loop step output mode according to a preset self-learning algorithm. When the corrected signal meets a preset output condition, the signal is output as a target signal. No matter whether the loadchange of the DC transient step signal source results in the distortion of the DC transient step signal, the target signal corrected through self-learning is close to the transient waveform under a real fault. Therefore, the method and the device can adapt to the load characteristics of DC transformers based on various principles, and the technical problem that the existing DC transformer transient step source adopts an open-loop power amplifier step output mode and can hardly adapt to the load characteristic change of DC transformers based on various principles is solved.
Description
technical field [0001] The present application relates to the technical field of electric power system and automation thereof, in particular to a method and device for adaptively adjusting a DC transient step source signal. Background technique [0002] The transient step characteristic is an important parameter index to measure the response and restoration of the original signal of the DC transformer when the electrical quantity of the primary system changes. Great impact. The test conditions for DC transformers to be tested in the factory and on-site in China are very scarce. Generally, only factory inspection tests have been carried out, and the steady-state accuracy of DC is mainly tested. There is a lack of research on the transient step characteristics of transformers and corresponding High-current high-performance test power source implementation technology. In engineering applications, there are clear requirements for the rise time, overshoot, and stabilization tim...
