图1：系统拓扑图 | Figure 1: System Topology Diagram |
整套系统配置10寸本地触摸屏，实现本地数据监控、触摸功能操作；配置1路RS485通讯接口，支持遥控、遥测、遥调远程功能。系统由双向DCDC变换单元、ACDC整流单元组成；交流电源经ACDC单元转换接入直流母线，超级电容经由双向DCDC单元接入直流母线，实现交流电网?直流母线?超级电容三者之间双向能量交互。
The system is equipped with a 10-inch local touch screen for on-site data monitoring and touch-based operation. One RS485 communication port is provided for remote telecontrol, telemetry and tele-adjustment. The system consists of bidirectional DC-DC converter units and ACDC rectifier units. AC power is converted via ACDC units to the DC bus; super-capacitors connect to DC bus through bidirectional DC-DC units, realizing bidirectional energy interaction among AC grid, DC bus and super-capacitors.
