摘要
快速发展的电气化铁路带来便捷的同时也会产生谐波,导致电压波动和电压偏差,降低电网电能质量。以太原某电气化铁路工程为例,研究电气化铁路对电网造成的影响,从电压偏差、电压波动、谐波电压和谐波电流等方面做出评估,并提出治理方案,经过FC和TCR治理后,电网电能质量得到显著改善,电压偏差和谐波电流减小70%,电压波动减小80%。
While the rapid development of electrified railway brings convenience, it will also produce harmonics, resulting in voltage fluctuation and voltage deviation, and reducing the power quality of the grid. Taking an electrified railway project in Taiyuan as an example, this paper studies the impact of electrified railway on the power grid, makes an assessment from the aspects of voltage deviation, voltage fluctuation, harmonic voltage and harmonic current, and proposes a governance scheme. After FC and TCR governance, the power quality of the power grid has been significantly improved, with voltage deviation and harmonic current reduced by 70%, and voltage fluctuation reduced by 80%.
