With the development of power system, rapid, accuracy and strong self-healing automation management for modern smart grid will greatly enhance the automation and intelligence of power grid. IEC61850 can support a uniform standard for smart grid and achieve the plug and play and interoperability for devices. Therefore, an information laying approach between different control laying is presented in this paper. And information exchange model and devices models including HVDC system are built. Then remote control and measurement, and mapping principle of control and protection system are discussed and analyzed. IEC 61850 can effectively enhance the feasibility, operability and robustness for smart grid.
