![]() ![]() ![]() Inter-Control Center Communications Protocol To meet these special requirements for communication and co-ordination between control centres the IEC developed the IEC 60870 set of standards. However, none of these communication protocols were suited to the requirements of communicating between control centres. These were followed by the development of "open" industry-standard protocols such as DNP3 and IEC 61850. Initially individual SCADA manufacturers developed their own proprietary "closed" protocols for communicating from a control centre to electrical equipment in the field. However, the development of SCADA ( supervisory control and data acquisition) systems allowed remote control and monitoring of electrical plant from centralised control centres. Prior to the development of electronics and telecommunications networks all co-ordination between control centres was carried out by telephone. distribution control centres, responsible for the distribution of power from the transmission networks to individual consumers. ![]() transmission control centres, responsible for the transmission of power from generating stations to network distributors.generation control centres, responsible for managing the operation of generating plants (coal-fired, natural gas, nuclear, solar, wind, etc.), and for adjusting the power generated according to the requirements of the system control centre.one or more system control centres, responsible for scheduling of power generation to meet customer demand, and for managing major network outages and faults.IEC 62 Functional profile for providing the TASE.2 application service in end systemsĪ typical national power grid includes a hierarchy of control centres to manage the generation, transmission, and distribution of power throughout the grid:.IEC 61 Functional profile for providing the TASE.1 application service in end systems.IEC 61 Functional profile for providing the connection-oriented transport service in an end system connected via permanent access to a packet switched data network.IEC 6 Use of basic standards (OSI layers 1–3).IEC 6 Application context and organization of standards.3 Inter-Control Center Communications Protocol. ![]()
