摘要
柔性直流牵引供电系统是城轨交通牵引供电技术的重要发展方向,而潮流计算是对其进行分析和设计的重要依据。柔直牵引供电系统的潮流分布直接受到系统级控制的影响,因此需要在潮流计算中计及系统级控制。本文基于高斯迭代法,研究了柔直牵引供电系统的建模问题,设计了能可靠收敛的潮流算法,解决了在柔直牵引供电系统潮流计算中考虑系统级控制问题。最后结合北京地铁16号线的实际情况,验证了算法的有效性,并对系统的经济技术特性进行了分析和比较。
Voltage source converter based DC traction power supply system is a promising trend of urban traction power supply technology,and power flow is an important basis for its analysis and design.The power flow distribution of the voltage source converter based traction power supply system is directly affected by the system-level control,so it is necessary to include system-level control in the power flow calculation.In this paper,based on the Gauss iteration method,the modeling of the voltage source converter based traction power supply system is studied,and a reliable convergence power flow algorithm is designed,which solves the problem of including system-level control in the calculation of the voltage source converter based traction power supply system.Finally,with the actual situation of Beijing Subway Line 16,the effectiveness of the algorithm is verified,and the economic and technical characteristics of the system are analyzed and compared.
