牵引供电系统对埋地管道阻性耦合交流干扰建模及仿真
|
摘要
牵引供电系统对埋地管道阻性耦合干扰原理分析表明,埋地管道的管地电位主要受"钢轨—大地"回路传播常数的影响,由牵引供电系统的电气拓扑结构及其设计参数决定。在此基础上,运用CDEGS软件建立牵引供电系统对埋地管道的阻性耦合交流干扰模型,计算牵引供电系统的短路阻抗和埋地管道的管地电位,与传统Carson理论计算结果的对比验证了该模型的准确性。针对牵引供电系统特殊的电气拓扑结构,研究牵引变电所接地电阻、回流网阻抗和钢轨泄漏电阻在电力机车距牵引变电所不同位置时,对埋地管道管地电位的影响。结果表明:牵引变电所接地电阻越小,埋地管道距牵引变电所越近,其管地电位越高;与单线铁路相比,采用上下行钢轨横联方式的复线铁路,降低了回流网阻抗,也降低了埋地管道的管地电位;钢轨对地绝缘防护越好,钢轨泄漏电阻越大,埋地管道的管地电位越低。
The analysis of resistive coupling interference principle of traction power supply system to buried pipeline shows that,the pipe-ground potential of buried pipeline is mainly affected by the propagation constant of"rail-earth"loop,which is determined by the electrical topology of traction power supply system and its design parameters.On this basis,by using CDEGS software,a model for the resistive coupling AC interference of traction power supply system to buried pipeline is established.Meanwhile,the accuracy of the model is verified by comparing the short-circuit impedance of traction power supply system and the pipe-ground potential of buried pipeline with the calculation results of traditional Carson theory.In the light of the special electrical topology of traction power supply system,the influence of traction substation grounding resistance,return flow network impedance and rail leakage resistance on the pipe-ground potential of buried pipeline is analyzed at different positions of electric locomotive from the traction substation.Results show that the smaller the grounding resistance of traction substation,the closer the buried pipeline is from traction substation and the higher is its pipe-ground potential.Compared with single-track railway,the double-track railway with cross-linking of up and down rails reduces the impedance of return flow network and also reduces the pipe-ground potential of buried pipeline.The better rail insulation protection,the greater the rail leakage resistance,the lower the pipe-ground potential of buried pipeline.
