Abstract
The present invention provides a wide area protection control measurement system and method which excels in economy, reliability and expandability, in which applied arithmetic operation functions for protection, control and measurement can be freely added and changed, without adding or changing power monitoring terminals to be installed in the electric-supply station. The wide area protection control measurement system is configured from N number of power monitoring terminalsinstalled in an electric-supply station in a target range, one electric quantity aggregation deviceconnected with these power monitoring terminalsvia a communication network, and M number of applied arithmetic operation devicesconnected with the electric aggregation devicethrough an inter-device connection. Each power monitoring terminaltransmits electric quantity data to the electric quantity aggregation devicevia the communication network. The electric quantity aggregation deviceaggregates received electric quantity data to generate aggregated electric quantity data and outputs it to each applied arithmetic operation devices. Each applied arithmetic operation devicesperforms applied arithmetic operation for protection, control or management, using the aggregated electric quantity data acquired from the electric quantity aggregation device
