【摘要】 通过对哈大线长春北牵引变电所的负荷特点和运行方式的分析,提出了采用全新的SVG(静止无功发生器)技术对长春北牵引变电所的电力机车负荷进行动态无功补偿。对SVG技术应用于单相供电系统的原理、依据和实现手段进行了较系统的研究,并使用Matlab6.5/Simulink对SVG系统进行了仿真研究。在此理论基础上,提出了SVG模块并联和串联运行的2种结构,并分析了2种结构的特点。更多还原

【Abstract】 In the paper, after analyzing the characteristic of load and the running mode at Chang Chun North traction substation, puts forward a new technique –SVG(Static Var Generator) to compensate the reactive power at Chang Chun North traction substation. Studying the theory, gist and actualizing method of the single-phase SVG technique and simulating the SVG using of Matlab 6.5/Simulink. On the base of the theory, puts forward the parallel connection SVG module and the series connection SVG module, and analyzes the characteristic of two structure.更多还原
