Connected to high-voltage power system directly, electrified railway is a particular user to power system, and its loads have the characteristics such as non-liner, asymmetry and volatility and so on. Researched on Chunshen traction substation which belongs to Shanghai-Hangzhou electrified railway, and accorded to the requirements and characteristics of comprehensive management to harmonics, reactive...
With the widespread use of large-capacity power electronic devices, there are too much harmonic current and harmonic voltage in power system at the same time. The active power filter (APF) or hybrid active power filter (HAPF) can only eliminate harmonic current or harmonic voltage, and possibility resonance. To eliminate harmonic current and harmonic voltage in power system simultaneously and enhance...
