摘要
为了满足电动汽车充放储一体化站的运营要求,提出了一种新型的多用途变流装置拓扑结构,对该变流装置在充电、换电、半放电和全放电四种不同运行状态下的工作特性及控制方法进行了相应的分析和设计,运用EMTP、PSCAD等电力系统仿真软件对变流装置的各个运行方式进行仿真,通过对仿真结果的分析,验证了该多用途变流装置可对一体化站能量流动方式进行有效的支持,并在四种运行状态下均能实现很好的能量管理效果。
In order to meet the operational requirements of the electric vehicle charge discharge storage integrative station, a new kind of the multi-purpose converter based on topology structure is proposed, its operating characteristics are analyzed under four running states, such as charging, DC-converting, semi-discharging and discharging and the corresponding control methods of the multi-purpose convert in different running states are presented. This paper also verifies the feasibility of the multi-purpose converter through EMTP/PSCAD simulation analysis and illustrates the correctness of the multi-purpose con- verter to support the energy flow of the integrative station.
