| Abstract |
There are several protective relays used to protect DC traction power supply system for DC railway. These relays, however, are made by different manufactures and they have different ways for their operations. Therefore, there are difficulties for cooperation between the devices or the devices and an upper system. In order to increase interoperability and stability of the system composed of devices made by different manufactures, IEC 61850 international standards are applied to design logical nodes for modeling protective elements used in protective relays. |
