Abstract

According to an embodiment of the present disclosure, there is provided a preventive diagnostic system for a GIS that includes a plurality of data acquisition systems (DAS's), a central communication unit (CCU), and a local server. The DAS generates an ICD file representing a content of the configuration of the DAS using a logical node designed for the preventive diagnostic system for a GIS and delivers the ICD file to the CCU, and the CCU performs a network connection so as to communicate with the DAS in compliance with IEC 61850 based on a content of the ICD file delivered from the DAS. According to the embodiment of the present disclosure, by applying IEC 61850 to the preventive diagnostic system for a GIS, smooth integration with a substation automation system and an efficient operation can be achieved.

First claim

What is claimed is:

1. A preventive diagnostic system for a gas insulated switchgear (GIS) based on IEC 61850, the preventive diagnostic system comprising:
a plurality of data acquisition systems (DAS's) being disposed in the GIS and receiving sensing data of partial discharge from a plurality of partial discharge sensors when the partial discharge occurs;
a central communication unit (CCU) transferring the received sensing data to a local server in real time; and
the local server generating report data using the sensing data received from the CCU and providing the report data to a user through an human machine interview (HMI) screen,
wherein the DAS generates an intelligent electronic device (IED) capability description (ICD) file representing a content of the configuration of the DAS using a logical node designed for the preventive diagnostic system for a GIS and provides the CCU with the ICD file, and
wherein the CCU performs a network connection so as to communicate with the DAS in compliance with IEC 61850 based on a content of the provided ICD file, and
the CCU comprises:
a configuration tool generating a database used for a system operation, configuring a gateway system to which the DAS is connected and a system configuring the DAS, automatically generating tags, and selecting a value to be used from among a plurality of values of the DAS;
an operation tool controlling operations of the DAS's; and
a value viewer tool monitoring and controlling values received from the DAS's.

2. The preventive diagnostic system for a GIS based on IEC 61850 according to claim 1 , wherein the CCU converts IEC 61850 data into channel data.

3. The preventive diagnostic system for a GIS based on IEC 61850 according to claim 1 , wherein the CCU converts IEC 61850 data into channel data.

4. The preventive diagnostic system for a GIS based on IEC 61850 according to claim 1 ,
wherein the DAS comprises an IEC 61850 COM client that interfaces with the CCU so as to transmit constituent elements and a measured value to the CCU, and
wherein the IEC 61850 COM client operates or stops the DAS in accordance with a DAS operation or stop command received from the CCU and controls and monitors the DAS in accordance with a DAS control and monitoring command.

5. The preventive diagnostic system for a GIS based on IEC 61850 according to claim 1 , wherein the ICD file includes:
network information in which a MAC address and an IP address for MMS communication and GOOSE communication are set;
service information including information for functions serviceable in the DAS; and
logical node information including information for the logical node provided by the DAS.

6. The preventive diagnostic system for a GIS based on IEC 61850 according to claim 1 , wherein a communication card capable of performing IEC 61850 communication is mounted in a case where a CPU is not mounted in the DAS.

7. The preventive diagnostic system for a GIS based on IEC 61850 according to claim 1 , wherein the ICD file comprises an extensible markup language (XML) file.

8. A preventive diagnostic system for a gas insulated switchgear (GIS) based on IEC 61850, the preventive diagnostic system comprising:
a plurality of data acquisition systems (DAS's) being disposed in the GIS and receiving sensing data of partial discharge from a plurality of partial discharge sensors when the partial discharge occurs;
a central communication unit (CCU) transferring the received sensing data to a local server in real time; and
the local server generating report data using the sensing data received from the CCU and providing the report data to a user through an human machine interface (HMI) screen,
wherein the DAS generates an intelligent electronic device (IED) capability description (ICD) file representing a content of the configuration of the DAS using a logical node designed for the preventive diagnostic system for a GIS and provides the CCU with the ICD file, and
wherein the CCU performs a network connection so as to communicate with the DAS in compliance with IEC 61850 based on a content of the provided ICD file and
wherein the DAS comprises an IEC 61850 COM client that interfaces with the CCU so as to transmit constituent elements and a measured value to the CCU, and
wherein the IEC 61850 COM client operates or stops the DAS in accordance with a DAS operation or stop command received from the CCU and controls and monitors the DAS in accordance with a DAS control and monitoring command.

9. A preventive diagnostic system for a gas insulated switchgear (GIS) based on IEC 61850, the preventive diagnostic system comprising:
a plurality of data acquisition systems (DAS's) being disposed in the GIS and receiving sensing data of partial discharge from a plurality of partial discharge sensors when the partial discharge occurs;
a central communication unit (CCU) transferring the received sensing data to a local server in real time; and
the local server generating report data using the sensing data received from the CCU and providing the report data to a user through an human machine interface (HMI) screen,
wherein the DAS generates an intelligent electronic device (IED) capability description (ICD) file representing a content of the configuration of the DAS using a logical node designed for the preventive diagnostic system for a GIS and provides the CCU with the ICD file, and
wherein the CCU performs a network connection so as to communicate with the DAS in compliance with IEC 61850 based on a content of the provided ICD file and
wherein the ICD file includes:
network information in which a MAC address and an IP address for MMS communication and GOOSE communication are set;
service information including information for functions serviceable in the DAS; and
logical node information including information for the logical node provided by the DAS.
