Webinar led by Thierry Buhagiar, RTE.
This webinar on the generalities of telecommunications and telecontrol for a power network is based on the system deployed at Réseau de Transport d'Électricité, the French high and extra-high voltage network operator.
Particularities are identified so that viewers can easily identify what are the usual situations.
The first part of the presentation introduces the telecoms network (known at RTE as the safety network), focusing initially on the functions it supports: telecontrol of power networks, telephony and teleprotection.
The webinar goes into more detail on the telecontrol function only.
The network structure is then described: transmission media, data transport and applications used. Equipment such as switches, routers and federators are presented and their functions explained. The TCP/IP protocol is briefly described.

The telecommunications structure between regional control centers, national control centers and power generation sites is presented; this high-level network is known as RMS (multi-service network).
The so-called low-level structure connects substations to a first grouping level (grouped control substations) and then from these to the regional control centers.
The webinar covers the structure of these two levels, the protocols used and the means of supervision and administration. Numerous illustrations present the equipment.
Part of the presentation focuses on the configuration of data essential to power system control, and the means used to guarantee its reliability and completeness.
Telecommunications equipment asset management is also covered.
The full webinar material covers other topics that complement the webinar presentation.
