Abstract :
The necessity to design special methods and tools for prevention of asynchronous operation is caused by the presence of long transmission lines and structure of the transmission grid of Baltic States and Russia. The method for prevention and elimination of asynchronous operation by means of two automatic devices based on angle control between two simulated voltages is presented in this paper. For voltages simulation GPS and fiber optic communication channels are used. The main problems of devices realization, application and testing are discussed.
