ABSTRACT:
A network which simplifies structure, realizes autonomous automation, digitalizes data, and effectively uses data is disclosed. A measuring card for measuring voltage and current according to values detected by the state detector that detects voltage and current of the system. A protection card performs a protective arithmetical operation according to values detected by the state detector and outputting a protection command to a controller. A control card performs a protective arithmetical operation according to values detected by the state detector and outputting a control command to a controller are integrated within an on-site cubicle. The protection card, measuring card, and control card are connected to the substation monitoring and controlling device via a serial bus which is shared by those cards, and data is sent and received between those cards and the monitoring and controlling device via the serial bus.
