Electrical distribution system is the largest portion of network in the electrical power system. There is voltage drop on long HV distribution line (D/L) due to heavy load consumption, absent of voltage regulation, as well as poor power factor collection on long HV D/L. Therefore, phase advancing capacitors (Shunt Capacitor, SCs) are installed in parallel with customer loads for voltage improvement and power factor correction. However, these SCs, sometimes, lead to Ferranti effect, especially at the very lightly loaded condition. Moreover, in recent years, the introduction of photovoltaic power generation systems (PV systems) into HV D/L has developed rapidly and may cause the unacceptable voltage variation on HV D/L.\n In this study, a virtual 6.6 kV long distance (20 km) HV D/L without PV system supported from Kyushu Electric Power Company (Qden) in Miyazaki branch, is introduced. In this long distance HV D/L, a 20 MVA transformer, three static voltage regulators (SVRs), and 50 customer loads are included. For very lightly loaded condition, the effects of SCs detachment area on the voltage profiles of HV D/L are numerically investigated and discussed. Moreover, the optimal location is proposed to change the suitable SVR for the purpose of upgrading voltage drop in heavy loaded condition.\n Then, voltage profiles of different lengths (20.3 km for long and 8.70 km for short) HV D/Ls with PV system installing SCs at customer’s side and different load capacity are discussed. Furthermore, the conditions of flowing line current on HV D/L with PV system for different load locations are explained with phasor diagram. A program based on the Newton Raphson method was coded for the power flow calculation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Engineering, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00732558","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05404924","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Khaing, May Thin","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"33697","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakoda, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"12874","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90310028","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90310028"}]},{"creatorNames":[{"creatorName":"Hayashi, Noriyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14214","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-10-26"}],"displaytype":"detail","filename":"Engineering_50_p95-p103.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://miyazaki-u.repo.nii.ac.jp/record/6414/files/Engineering_50_p95-p103.pdf"},"version_id":"0a963ccd-77f6-4e64-9012-12644bfddf3d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"high voltage distribution line","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"PV system installation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"voltage variation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shunt capacitor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"static voltage regulator","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Voltage Profi les on HV Distribution Lines with Various Network Confi gurations and Customers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Voltage Profi les on HV Distribution Lines with Various Network Confi gurations and Customers","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["73","36","330","484"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-10-26"},"publish_date":"2021-10-26","publish_status":"0","recid":"6414.3","relation_version_is_last":true,"title":["Voltage Profi les on HV Distribution Lines with Various Network Confi gurations and Customers"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2023-07-29T11:26:20.418038+00:00"}
