Substation system
First Claim
1. A substation system comprising a state detector for detecting the state of monitored objects connected to a power system;
- a controller for controlling controlled objects connected to said power system according to control information;
a monitor-information creating device for exchanging information with said state detector using digital signals as media and also creating information about the state of said monitored objects; and
a control-information creating device for creating control information for controlling said controller, converting the created control information along with received control information into digital signals and transmitting the signals to said controller, wherein said monitor-information creating device and said control-information creating device are connected to a monitoring and controlling device for collecting information about the state of said monitored objects and outputting control information for controlling said controlled objects via a signal transmission path shared by those devices, and exchange information with said monitoring and controlling device using digital signals as media.

Abstract
To simplify the structure, realize autonomous automation, digitalize data, and effectively use data by utilizing a network. 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 for performing a protective arithmetical operation according to values detected by the state detector and outputting a protection command to a controller, and a control card for performing 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, wherein 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.
