| 摘要: |
| 电动汽车换电站（BSS）向电网放电是实现V2G的一种重要方式，该运行方式可能会对中压配电网保护带来负面影响。给出了换电站中充放电机的拓扑结构及其详细的控制模型，在此基础上在PSCAD ／ EMTDC中建立了含换电站的10 kV配电网仿真模型。仿真结果表明，换电站电气量特征在不同的配电网故障特征情况下明显不同，换电站运行状态改变对配电网的故障特征有显著影响。 |

| Abstract: |
| Discharging from BSS（Battery Swap Station） to power grid is an important operating mode of V2G（Vehicle to Grid），which may bring negative influence on the protections of medium voltage distribution network. The topology and detailed control model of the charging ／discharging device in BSS are given，based on which，a simulation model of 10 kV distribution network with BSS is built on PSCAD ／ EMTDC. Simulative results show that，the electrical characteristics of BSS are quite different under different fault characteristics of power grid and the change of BSS operating state makes strong impact on the fault characteristics of distribution network. |
