摘要 神朔电气化铁路是我国重要的"西煤东送"大动脉,有大量的交直机车和交直交机车混跑。因此,牵引网中同时存在大量的高、低次宽频谱谐波,对供电品质造成不利影响。针对该问题,建立了车网一体等效电路模型,分析了牵引网的谐波特性,提出了一种新型注入式混合补偿方法,并对其补偿原理、谐波电流检测和控制算法进行了详细阐述。仿真结果表明:该混合补偿方法可实现对宽频谱谐波的综合治理,大大减少有源补偿容量,性价比高。 In China, Shenshuo electrified railway is one of the most important main artery that the western coal is transported to the east, where DC locomotives and AC locomotives are running at the same time. Thus, there are so abundant high and low frequency wide spectrum harmonics that have an adverse impact on power supply quality in this line. According to this situation, the equivalent circuit model of vehicle network was established, and harmonic characteristic on traction network was analyzed. A new type of injection hybrid compensation method was put forward, which was introduced from its compensation principle, harmonic current detection and control algorithm. The simulation results showed that this method could realize comprehensive treatment of the wide spectrum of harmonic, and obviously reduce active compensation capacity with high cost performance.
