摘　　要：随着大功率开关管越来越广泛的使用,电流谐波对电力系统的影响日益加重,导致整个系统电能质量逐渐下降。该文设计并实现一种基于CAN总线的支路控制器,该控制器通过对支路电流的实时采集、频谱分析实现对支路电流谐波的在线检测,如发现支路电流谐波异常,该控制器通过CAN总线上报主控节点,由主控节点统筹决策。主控节点的决策指令通过CAN总线下达到控制器,可指示控制器切断支路,以保障主控节点下的全局电能质量。该控制器在一个芯片完成电流采集、分析、通信和控制,多个控制器通过总线串联连接,具有接线简单、体积小、成本低的特点,为保障电力供给的稳定性和电能质量提供一种解决方案。With the increasing widespread use of high-power switches,the impact of current harmonics on the power system is increasing,thus resulting in the gradual decline of the power quality of the whole system.In this paper,a branch controller based on CAN bus is designed and implemented.the controller realizes on-line detection of branch current harmonics through real-time collection of branch current and spectrum analysis.If branch current harmonics are found,the controller reports to the main control node through the CAN bus,and the master node makes overall decisions.The decision instruction of the main control node is sent to the controller through the CAN bus,which can instruct the controller to cut off the branch to ensure the global power quality under the main control node.The controller completes current acquisition,analysis,communication and control in one chip,and multiple controllers are connected in series through the bus,which has the characteristics of simple wiring,small size and low cost.It provides a solution to ensure the stability of power supply and power quality.
