| Abstract: | The electric locomotive is the main unbalance load and harmonic source load of the traction power system.The high-frequency harmonic currents generated in its running process will do great harm to its safe and stable operation.In order to detect the harmonics in the traction power system accurately and on a real-time basis,wavelet transform with good time-frequency localization is used in harmonic analysis.Type HXD3-0017 Electric Locomotive was taken as an example to analyze the harmonic current characteris... |
