光伏接入牵引供电系统谐波交互影响及其适应性分析
|
摘要
为了分析光伏接入牵引供电系统的谐波交互影响及其适应性,基于谐波传输理论,建立了系统谐波电流分析模型;利用MATLAB/Simulink搭建了光伏-全并联自耦变压器牵引网-动车组耦合系统的联合仿真模型,并验证了模型的准确性;在此基础上,分别针对牵引侧、光伏侧的动态工况进行仿真,对比分析了光伏接入前/后系统谐振及谐波放大特性、牵引网稳态电压分布、不同母线侧谐波电压/电流畸变情况以及光伏逆变器的耐受能力。通过实测数据对牵引供电系统接纳光伏的能力进行算例分析,结果表明:当光伏的装机容量较小时,光伏发电系统与牵引供电系统之间谐波的交互影响较小,两者均表现出较好的适应性。
In order to analyze the harmonic interaction influence and its adaptability of PV(PhotoVoltaic) generation system accessing to traction power supply system,the system harmonic current analysis model is established based on harmonic transmission theory. The united simulation model for the coupled system of PV,all-parallel AT(Auto-Transformer) traction network and electric multiple units is set up in MATLAB/Simulink and its accuracy is verified. Based on this,the dynamic working conditions of traction side and PV side are simulated respectively,and the resonance and harmonic amplification characteristics of the system,the steady-state voltage distribution of traction network,the harmonic voltage/current distortion of different bus sides and the resistant ability of PV inverters are ana-lyzed and compared before and after the integration of PV generation system. The accommodation ability of traction power supply system to PV generation is studied based on measured data,and results show that when the installed capacity of PV generation system is smaller,the harmonic interaction influence between traction power supply system and PV generation system is smaller,and both of them show good adaptability.
