Abstract: A distributed monitoring and protection system for a distributed power network. The system includes a plurality of high-speed measuring units (MUs), wherein each MU is coupled to a power line to measure values of electrical parameters of the power line. Electrical parameters, such as current, voltage, power and frequency are measured by the MUs. The MUs communicate with a control unit (CU) over a high-speed communications network. The CU includes a processor executing algorithms for evaluating the measured parameters to determine the status of the power network and the MUs. The processor also executes fault detection and isolation by comparing the measured values against predetermined threshold values. When a fault is detected by the CU, protective action, such as tripping of a circuit breaker, may be initiated by the CU directly or by transmitting the tripping command over the high speed data network to a local MU. The local MU may then trip the circuit breaker. The availability at the CU of concurrent measurements from the plurality of MUs enables improved coordination and sequencing of protective actions.

Abstract translation: 一种用于分布式电力网络的分布式监控和保护系统。 该系统包括多个高速测量单元（MU），其中每个MU耦合到电力线以测量电力线的电气参数的值。 电气参数，如电流，电压，功率和频率由MU测量。 MU通过高速通信网络与控制单元（CU）通信。 CU包括执行用于评估测量参数以确定电力网络和MU的状态的算法的处理器。 处理器还通过将测量值与预定阈值进行比较来执行故障检测和隔离。 当CU检测到故障时，可以由CU直接启动保护动作，例如断路器的跳闸，或者通过高速数据网络将跳闸命令发送到本地MU。 本地MU可能会跳闸断路器。 CU的多个MU的并发测量的可用性使得能够改善保护动作的协调和排序。
