After studying much about the power transmission mode of electrical railway and its effect on power system,this thesis improved Steinmetz theory and proposed a simple method:integrated negative-sequence admittance,which aimed to compensate three-phase unbalanced load.
本文在全面了解我国电气化铁路供电模式及其对电力系统产生的影响的基础上,对利用Steinmetz原理治理三相不平衡和提高功率因数的算法进行了改进,提出了更加简洁的综合负序导纳新算法用于补偿三相不平衡负载。
A multi-infeed HVDC system model including AC/DC parallel lines was established,and the relation between its mutual admittance and converter commutation failure was analyzed.
建立了2条交、直流并联的多馈入高压直流输电系统模型,并对此模型的直流输电线的耦合导纳和换相失败关系进行详细的理论分析研究。
