The system consists of several components such as DC power supply, switching network unit, quench protection circuit and motor-generator. All the components\nhave their own internal controller (LCC) for stand-alone operation so the individual commissioning are in progress and almost completed. The next step scheduled is a combination test with all components in which supervisory control system manage LCCs remotely. The supervisory system covers the following roles: 1) machine status monitoring; 2) discharge sequence management; 3) real-time reference waveforms management; 4) data acquisition; 5) machine protection; 6) human safety. The supervisory system consists of several subsystems; PS supervising computer (PS-SC), PS programmable logic controller (PS-PLC), PS internal protection\nsystem(PS-IPS) and PS safety interlock system (PS-SIS). PS-SC covers the primary roles in 1) – 4) which is built on CompactPCIs with real-time OS INtime. PS-SC and LCCs are linked through a Reflective Memory (RM) network to share common data in real-time (4 kHz). PS-SC is also linked to the upstream JT-60SA supervisory control system (SCSDAS) via another RM network as an interface for the power supply internal control systems. During discharge sequence, PS-SC also manages motor-generator speed, AC circuit breakers OPEN/CLOSE status with a controller PS-PLC and magnets current according to request from SCSDAS. PS-IPS covers the function of 5) which is implemented on FPGA. PS-IPS is connected to LCCs via fiber optical and hard-wired signals. In case of emergency events such as magnet quench and earth quake, PS-IPS commands to shut down the magnets currents immediately. PS-SIS plays the role in 6) such as status and permission of fence OPEN/CLOSE and grounding switch for maintenance. In this presentation, overview and development of the supervisory system are described.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"30th edition of the Symposium on Fusion Technology (SOFT 2018) ","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hatakeyama, Shoichi"}],"nameIdentifiers":[{"nameIdentifier":"798134","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimada, Katsuhiro"}],"nameIdentifiers":[{"nameIdentifier":"798135","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamauchi, Kunihito"}],"nameIdentifiers":[{"nameIdentifier":"798136","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsukawa, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"798137","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moriyama, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"798138","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Baulaigue, Olivier"}],"nameIdentifiers":[{"nameIdentifier":"798139","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Gaio, Elena"}],"nameIdentifiers":[{"nameIdentifier":"798140","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maistrello, Alberto"}],"nameIdentifiers":[{"nameIdentifier":"798141","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ferro, Alberto"}],"nameIdentifiers":[{"nameIdentifier":"798142","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Novello, Luca"}],"nameIdentifiers":[{"nameIdentifier":"798143","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Frello, Giampaolo"}],"nameIdentifiers":[{"nameIdentifier":"798144","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Lampasi, Alessandro"}],"nameIdentifiers":[{"nameIdentifier":"798145","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zito, Pietro"}],"nameIdentifiers":[{"nameIdentifier":"798146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatakeyama, Shoichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"798147","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimada, Katsuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"798148","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamauchi, Kunihito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"798149","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsukawa, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"798150","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moriyama, Shinichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"798151","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Development of Supervisory Control System for Magnet Power Supplies in JT-60SA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of Supervisory Control System for Magnet Power Supplies in JT-60SA"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-25"},"publish_date":"2018-10-25","publish_status":"0","recid":"72985","relation_version_is_last":true,"title":["Development of Supervisory Control System for Magnet Power Supplies in JT-60SA"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:51:44.228910+00:00"}
