  • IPCOMM delivered ipConv gateways to link the SIPROTEC UT612,13,33/35 protection devices and the TDC control system with the IEC 60870-5-101 master station.
    The transmission of messages from the RTU using IEC 60870-5-101 protocol via the gateway to the Simatic TDC control system is realized. The TDC is connected to the gateway with the proprietary protocol Simatic TDC.
    The SIPROTEC protection devices communicate with the gateway per IEC 60870-5-103 which sends directly specific protection-device-data via IEC 60870-5-101 protocol to the master station.
    The communication between the gateway and the master station is redundant.
    The gateway time is synchronized over the NTP protocol.

    This IPCOMM solution is part of the HVDC project COMETA.


    Red Eléctrica de España signed the contract with Siemens in October 2007 for design, delivery and construction of 2 x 200 MW HVDC bipolar converter stations. Commercial operation is scheduled for July 2011. The COMETA HVDC project, under the responsibility of Red Eléctrica de España, connects the Spanish peninsula with the Balearic island of Mallorca in order to meet the increasing demand of electric power on the island.
    The transmission system is designed as a bipolar interconnector with metallic return conductor. One converter station is located near the city of Valencia on the Spanish peninsula, where an existing power plant will be connected to the HVDC via a HIS Switchgear and HVAC cables (also supplied by Siemens). The other converter station on Mallorca is located at Santa Ponsa near the capital city Palma de Mallorca. The COMETA submarine link crosses the Mediterranean Sea in a maximum depth of 1,500 meters, has a length of approximately 250 km and will consist of three sea cables, one HV cable per pole and one cable as metallic return conductor.
