【摘要】 通过分析德大电气化铁路负荷特点,计算各牵引站注入供电系统公共连接点的谐波电流,应用ETAP软件仿真计算德大电气化铁路接入引起的公共连接点电压畸变及三相不平衡,对德大电气化铁路接入对山东电网电能质量的影响作出评估。更多还原

【Abstract】 On the basis of Deda electrical railway load’s analysis,each traction station harmonic current injected into the power supply system connection point was calculated.Through Electrical Transient Analyzer Program(ETAP),the voltage distortion and three-phase unbalance of point of common couple was simulated.Then the influence of Deda electrical railway’s access to Shandong power grid was concluded.更多还原
