Agent system for intelligent system management by digital substation and operation method therefor

An intelligent electronic device-side agent device for sharing switch information, which is used in automatic recovery of a digital substation, between an operating system and an intelligent electronic device (IED) in the digital substation, the device comprising a processor and a non-transitory memory coupled to the processor and storing instructions executable by the processor, the processor configured to:

• collect the switch information of a switch managed by the intelligent electronic device (IED), and transmit the switch information to an operating system-side agent device through a communication device, when the operating system-side agent device mounted in the operating system requests the switch information,
• wherein the intelligent electronic device-side agent device is provided as a module, and is mounted in the intelligent electronic device,
• wherein the switch information comprises a switch attribute of the switch, a question answer attribute used in request and response between the intelligent electronic device-side agent device and the operating system-side agent device, and an IEC 61850 standard based common data class (CDC) model attribute, and
• wherein the switch attribute comprises at least one of a circuit breaker name, state information of the switch managed by the intelligent electronic device (IED), a control type for the switch operated by the intelligent electronic device (IED), control availability information of the switch, and interlock configuration information and interlock signal information that are used for controlling the switch.

An operation method for an agent system including both an operating system-side agent device and an intelligent electronic device-side agent device, each of which comprises a processor and a non-transitory memory coupled to the processor and storing instructions executable by the processor, for sharing switch information, which is used in automatic recovery of a digital substation, between an operating system and an intelligent electronic device (IED) in the digital substation, the operation method comprising:

• collecting, by the processor of the intelligent electronic device-side agent device, the switch information of a switch managed by the intelligent electronic device (IED);
• requesting, by the processor of the operating system-side agent device, the switch information from the intelligent electronic device-side agent device;
• and
• receiving, by the processor of the operating system-side agent device, the switch information,
• wherein the operating system-side agent device and the intelligent electronic device-side agent device are respectively provided as modules, and are respectively mounted in the operating system and the intelligent electronic device,
• wherein the switch information comprises a switch attribute of the switch, a question answer attribute used in request and response between the intelligent electronic device-side agent device and the operating system-side agent device, and an IEC 61850 standard based common data class (CDC) model attribute, and
• wherein the switch attribute comprises at least one of a circuit breaker name, state information of the switch managed by the intelligent electronic device (IED), a control type for the switch operated by the intelligent electronic device (IED), control availability information of the switch, and interlock configuration information and interlock signal information that are used for controlling the switch.
