In order to solve the plug-and-play problem of key equipment of micro-grid and remove the adverse effects of large-scale distributed energy connecting to the grid upon relay protection of distribution network, design of micro-grid adaptive protection system based on IEC 61850 is proposed. The micro-grid adaptive protection algorithm is described, and unit equipment modeling for key equipment of micro-grid is made by using the logical node and data sets provided by the IEC 61850 standard. Through examples of micro-grid adaptive protection system and the data communication network transmission platform model in the OPNET software built by the examples, the average load on the center protection unit of micro-grid and network delay of micro-grid are simulated, and the feasibility of the communication network of micro-grid adaptive protection system based on IEC 61850 is verified.
