In the substation automation system and the data network of the power industry, the substation automation system should have not only the function of control implementatin, monitor as well as protection, but also the characteristic of interoperability with the purpose of realizing the information share between different manufacturers, which makes the substation automation system become an open system. Hence, the International Electrotechnical Commission (IEC) has established the communication network and system standard in substation--IEC 61850. The IEC 61850 protocol has introduced the substation configuration language SCL, which is used to describe the configuration of the intellectual electrical device as well as the communication system. It is easy to describe the relative relationshiop of the substation automation... |
