This paper analyzes the object-oriented modeling technology of IEC 61850 standard and the modeling steps of condition monitoring intelligent electronic devices (IED). Aiming at the problem of the existing configuration tools poor scalability for the IEC 61850 standard, a new design method of the IED configuration tool is brought up. Information model of transformer condition monitoring IED is established including logical device (LD), logical node (LN), data object (DO), data attribute (DA), dataset and report control block with the method mentioned above, and described with substation configuration description language.

Currently, the information exchange between various systems in substation is difficult, and the scheme of integrated supervision and control system of substation can effectively promote the smooth flow of information in the substation. In this paper, by analyzing the Communication architecture of integrated supervision and control system, the devices that communicate following the IEC61850 standard in station layer are given, which all need to integrate IEC61850 client. Then an integration method of IEC61850 client is proposed, providing unified IEC61850 client for different devices in integrated supervision and control system of substation to reduce the risk of interoperability failure because of using different IEC61850 clients. While a communication test is conducted using IED simulator and communication gateway simulator to verify the feasibility of the proposed integration method.
