TC 57 - Power systems management and associated information exchange
To prepare international standards for power systems control equipment and systems including EMS (Energy Management Systems), SCADA (Supervisory Control And Data Acquisition), distribution automation, teleprotection, and associated information exchange for real-time and non-real-time information, used in the planning, operation and maintenance of power systems. Power systems management comprises control within control centres, substations and individual pieces of primary equipment including telecontrol and interfaces to equipment, systems and databases, which may be outside the scope of TC 57. The special conditions in a high voltage environment have to be taken into consideration. Note 1: Standards prepared by other technical committees of the IEC and organizations such as ITU and ISO shall be used where applicable. Note 2: Although the work of TC 57 is chiefly concerned with standards for electric power systems, these standards may also be useful for application by the relevant bodies to other geographical widespread processes. Note 3: Whereas standards related to measuring and protection relays and to the control and monitoring equipment used with these systems are treated by TC 95, TC 57 deals with the interface to the control systems and the transmission aspects for teleprotection systems. Whereas standards related to equipment for electrical measurement and load control are treated by TC 13, TC 57 deals with the interface of equipment for interconnection lines and industrial consumers and producers requiring energy management type interfaces to the control system.
Gestion des systèmes de puissance et échanges d'informations associés
Etablir des normes internationales pour les équipements et systèmes de conduite des systèmes de puissance incluant EMS, SCADA, automation de la distribution, téléprotection et communications associées telles que les courants porteurs en ligne, qui sont utilisés pour la planification, le fonctionnement et l'entretien des systèmes électriques de puissance. La conduite des systèmes de puissance inclut la fonction de conduite des centres de conduite, les RTU et les postes y compris la téléconduite et les interfaces avec les équipements, systèmes et bases de données qui sont en dehors du domaine d'activité du CE 57. Note 1: Les normes rédigées par d'autres Comités d'Etudes de la CEI et d'autres organisations comme l'UIT et l'ISO seront utilisées lorsqu'elles sont applicables. Note 2: Bien que les travaux du CE 57 soient principalement orientés vers les normes applicables aux systèmes électriques de puissance, ces normes peuvent avoir leur utilité dans des applications faites par des organismes compétents à d'autres procédés intéressant de grandes étendues géographiques. Note 3: Bien que les normes relatives aux mesures, relais de protection et aux équipements de conduite et contrôle utilisées dans ces systèmes relèvent du CE 95, le CE 57 est chargé des interfaces avec les systèmes de conduite et des questions de transmission pour les systèmes de téléprotection. Bien que les normes relatives aux équipements de mesure électrique et de contrôle de la charge relèvent du CE 13, le CE 57 est chargé de l'interface avec l'équipement de lignes d'interconnexion et avec les consommateurs et producteurs industriels qui nécessitent des interfaces de type gestion de l'énergie avec le système de conduite.
