本文介绍了一种基于微处理器的相量测量系统与控制器局域网（CAN）总线通信能力的分布式发电机（DG）的控制。CAN总线协议允许在与电网的公共连接点处计算的电压和电流相量被广播到集群中的多个DG单元。集群中的每个DG单元可以承担监督角色，并执行符合用于DG与电力系统互连的IEEE 1547标准所需的公用设施接口控制功能。基于微处理器的相量测量系统基于20-30年前使用8位处理器开发的早期相量测量单元的技术和算法。利用现代微控制器沿着新颖的算法以低成本提供合理的性能。数值滤波提供的测量精度在标称电压幅值的约1%内，电压频率在约0.02 Hz内。
This paper describes a microcontroller-based phasor measurement system with controller area network (CAN) bus communication capability for control of a distributed generator (DG). The CAN bus protocol allows voltage and current phasors, calculated at the point of common connection with the grid, to be broadcast to several DG units in a cluster. Each DG unit in a cluster can assume the supervisory role and perform utility interface control functions needed for compliance with the IEEE 1547 standard for interconnection of DGs with electric power systems. The microcontroller-based phasor measurement system builds on technology and algorithms derived from early phasor measurement units developed 20-30 years ago using 8-bit processors. Utilizing modern microcontrollers along with novel algorithms provides reasonable performance at a low cost. Numerical filtering provides measurement precision to within about 1% of the nominal voltage magnitude and to within about 0.02 Hz in voltage frequency.
