摘要: |
为了更深入开展同相供电系统的研究,提出了一种由新型YNvd平衡牵引变压器、模拟负载以及综合潮流控制器(IPFC)构成的同相供电试验系统方案。分别介绍了YNvd平衡变压器、IPFC和模拟负载的结构和工作原理,通过对IPFC与模拟负载制定相应的控制策略,以实现对同相供电系统的仿真模拟。研究结果表明,该试验系统能够模拟牵引负荷特性,实现能量循环利用,模拟同相供电系统,消除了系统负序电流,实现了谐波和无功的动态补偿,验证了同相供电系统的可行性。 |

Abstract: |
In order to do further research on co-phase power supply system, a test system based on YNvd balanced transformer, simulated load and integrated power flow controller (IPFC) is proposed. By mean of analysis on structures and principles of YNvd transformer, IPFC and simulation load, establishing control strategy on IPFC and simulation load, the system is simulated dynamically. The results illustrate that this scheme can well simulate the traction load and cycle the energy, simulate co-phase system, eliminate the system negative sequence, and compensate harmonic and reactive power real-timely, which verifies the feasibility of co-phase power supply system. |
