要約(日本語): わが国では経済発展に伴う電力需要の増大に対応して，大規模遠隔集中電源の開発および基幹送電線・変電所の整備を行いながら，信頼性の高い電力系統を構築，運用してきた。一方，近年の電力自由化をはじめとした社会的要請から透明性の高い効率的な系統運用の推進が求められるとともに，高度情報化社会に多大な影響を及ぼす広域停電時などには迅速な復旧や情報発信が望まれており，電力系統運用を根底で支える変電所監視制御システムの重要性がさらに高まりつつある。
　このような情勢の下，この委員会は，2008年7月から2010年8月までの2年間，変電所監視制御システム技術の現状と今後の動向などの調査・検討を行ってきた。変電所監視制御システムは，変電所・開閉所の構内に設置され，構内系統の状態監視や遮断器開閉などの操作をになうシステムであり，遠方および現地での電力設備の監視制御や自動制御，故障部位の自動復旧，記録，運転・保守支援などの機能を備える監視制御盤から構成されるシステムである。
　本報告書は， いままで取り纏められたことのなかった変電所監視制御システムについて、「役割と位置付け」「全体構成と適用実態」「機能要素」に「海外の実態調査」「将来動向」を加え，体系的にまとめられている。本報告書は変電所監視制御システムに携わる技術者のみならず電力関係業務従事者，さらには電力工学を学ぶ学生の技術資源となることを目的とする。

要約(英語): In Japan, with increased power demand brought about by economic growth, highly reliable electric power systems have been built and operated by expanding trunk transmission lines, substations and large-scale power stations developed in remote areas intensively. Recently, more efficient and transparent power system operation has been required due to social requirements such as deregulation of the electrical power industry, and rapid restoration operation and information service are also desired in case of wide area black out, which has a significant impact on an advanced information-oriented society. In these situations, the importance of substation control and monitoring systems, supporting power system operation at the lowest layer in the power system, has been increasing. Under those circumstances, this committee has been investigating the current state of substation control and monitoring system technology and its trends in the future, during the two years from July 2008 to August 2010. A substation control and monitoring system is a collective system which is installed in a substation, performs status monitoring of power equipment and operation of switchgear in the substation, and consists of control panels which provide remote/local control functions, automatic control functions, automatic restoration functions for an area disconnected due to a fault condition, recording functions and operation and maintenance support functions.
This report describes the “role and position in the power system”, “system architecture and application” and “functions” for a substation control and monitoring system, which have not previously been considered as a subject for a report. Furthermore, “application in overseas countries” and “trends in the future” are covered.
This report aims to become a technological resource not only for engineers involved in substation control and monitoring systems, but also for other people engaged in the electric power business and moreover for students studying electric power engineering.
