Construction of integrated monitoring and telecontrol system in 500 kV Jiangmen Substation

After the establishment of China Southern Power Grid,500 kV Jiangmen Substation is faced with the problem of transmitting data to three master stations using different protocols.As a result, the originally independent monitoring system and telecontrol system in the substation are combined.Teletransmission function is added to the monitoring system and three separate teletransmission outlets included,which allow diverse protocol setting and correspond to different master station systems.Application results prove that the construction of the said system is successful.
