基于试验台的电网电源内阻测定研究

Study on Measurement of Source Impedance in Power Supply Based on a Test-bench

使用试验台建立一个测试电路,通过在该电路中产生各种干扰(改变外部负载的大小)来获取电压电流的瞬间变化情况,从而基于这些变化计算出电源内阻和短路电流水平的大小。

In this paper, the source impedance is measured by modelling a test circuit on a testbench and by adding some large and small disturbances(by changing external load) to make the voltage and current in the network have an opposite change and after capturing these changes, the source impedance can be measured.
