英文摘要：

The protection and control system of microgrid based on global information was presented and developed in this paper, which can monitor the operating status and operation mode of microgrid and clear different types of faults reliably. By connecting an industrial control computer with the protection units and grid-connection control unit in microgrid through communication network, the system realizes several fundamental functions, such as proper protection configuration, real-time monitoring of the operating status of the protection and grid-connection control units, simultaneous time setting, remote close/trip control, islanding detection, grid-connection control, manmachine information interaction and so on. The simulation results show that with a simple structure and practical functions, the protection and control system ensures safe and stable operation of microgrid.
