Abstract: Determination of electrical network topology and connectivity are described herein. A zero-crossing is indicated at a time when the line voltage of a conducting wire in an electrical grid is zero. Such zero-crossings may be used to measure time within a smart grid, and to determine the connectivity of, and the electrical phase used by, particular network elements. A first meter may receive a phase angle determination (PAD) message, including zero-crossing information, sent from a second meter, hereafter called a reference meter. The first meter may compare the received zero-crossing information to its own zero-crossing information. A phase difference may be determined between the first meter and the reference meter from which the PAD message originated. The first meter may pass the PAD message to additional meters, which propagate the message through the network. Accordingly, an electrical phase used by meters within the network may be determined.

Abstract translation: 本文描述了电网拓扑和连通性的确定。 当电网中的导线的线路电压为零时，表示过零点。 这样的过零点可用于测量智能电网内的时间，并确定特定网络元件使用的连接性和电相位。 第一仪表可以接收从第二仪表（以下称为参考仪表）发送的包括过零信息的相位角确定（PAD）消息。 第一台仪表可以将接收到的过零信息与其自己的过零信息进行比较。 可以在第一计量器和来自该PAD消息的参考计量器之间确定相位差。 第一个仪表可能会将PAD消息传递给附加的传感器，通过网络传播信息。 因此，可以确定网络中的计量表使用的电相位。
