Energy saving control method of recursive remote backup automatic switch in substation based on GOOSE communication

In order to save energy to the greatest extent on the basis of ensuring reliable power supply,a recursive remote backup automatic switching energy-saving control method for substation based on GOOSE communication is proposed.Combined with the characteristics of the incoming line of the standby automatic switching power supply,the basic principles to be observed in the control process are analyzed.The overall control architecture is designed based on GOOSE communication mode,which is divided into backup automatic switching device,switch locking and harmonic suppression modules,and defines the sending and receiving process of GOOSE message under the framework.By obtaining the voltage and current of the fault line,the position of the fault point can be judged,which is convenient for making control decisions.To build GOOSE output matrix,simulate the information sent by the sub device to the master station when a fault occurs,and set the response action of the standby automatic switching switch according to the meaning of each line vector in the matrix,so as to realize the energy-saving control of the standby automatic switching.Simulation results show that this method can effectively suppress harmonics,reduce power loss,and meet the development needs of green power grid.
