摘要
针对逆变型再生制动能量利用方案的供电计算问题,详细给出含逆变回馈装置的、精确考虑换相电阻的牵引变电所交直流变换数学模型和逆变型再生制动能量利用装置交流侧有功功率、无功功率、直流电压和直流电流的详细表达式。采用牛顿-拉夫逊法进行城市轨道交通供电计算,推导Jacobian矩阵,通过10节点直流牵引供电系统案例验证算法的有效性和准确性。
To address the issues of power supply calculation in the solution for inverter type regenerative energy by brake feedback,this paper gives a detailed description of AC/DC transform mathematical model in the tractionsubstation,which contains inverter feedback device and accurate consideration of the phase resistance,as well as a clear expression of the active and reactive power of AC side,voltage and current of DC side.By using Newton-Ralph method to solve the transit power supply calculation,and the Jacobian matrix is derived.The validation and accuracy ofthe algorithm are proved through a case study of10nodes DC traction power system.
