The political, economic and social events effused by blackout in and abroad are quite common.Electricity industries are being transformed worldwide, driven by the need for more energy, urbanization, scarcity of natural resources and global warming.Building a safe, reliable and highly stable power grid system has become an inevitable trend.The smart grid came into being therefore.The core feature of the smart grid as well as its primary goal is to build a safe and reliable power system, which covers all kinds of new developments in the network security control areas and is the improvement and development of the traditional dispatching control.Automatic control is an advanced modern communication technology.Automatic control system can improve network security and stability effectively, what refers to in the paper is a typical automatic control mode mentioned, the PI control, through theory and experiment we demonstrate the feasibility of improving the motors stability by PI control.
