The invention provides a charging pile power supply network topology identification method and system, and relates to the technical field of power system and new energy automobile charging, and the method comprises the steps: firstly distributing a unique ID to a charging pile, and carrying out the 8 coding; then the communication device sends a command to the charging pile and notifies the head end and the branch detection device to prepare to measure the power change; and after the charging pile receives the command, the charging pile outputs a preset power change according to a first preset time interval to form a guide code, and then transmits ID information according to a second preset time interval according to an integer multiple change of 1KW of an octal code control power of the ID. And the detection device monitors the loop, starts a receiving function according to the time and power variation standard, records and converts the power variation, restores the ID after receiving the end code, and determines the topological position of the charging pile. According to the invention, the problems of topology disorder, unreasonable load distribution and three-phase imbalance of the power supply system are effectively solved, and the charging efficiency and safety are improved.
本发明提供一种充电桩供电网络拓扑识别方法及系统,涉及电力系统与新能源汽车充电技术领域,该方法包括首先给充电桩分配唯一ID并8进制编码。接着通信装置向充电桩发送命令且通知首端与分支检测装置准备测功率变化。充电桩接收命令后,先按第一预设时间间隔输出预设功率变化形成引导码,之后按第二预设时间间隔依ID的8进制编码控制功率1KW整数倍变化传输ID信息。检测装置监测回路,依时间和功率变化量标准启动接收功能,记录并转换功率变化量,在收到结束码后还原ID并确定充电桩拓扑位置。本发明有效解决供电系统拓扑混乱、负荷分配不合理及三相不平衡问题,提升充电效率与安全性。
