DEVELOPMENT OF AUTOMATIC DEVICE FOR GENERATOR ACCELERATED SYNCHRONIZATION
Synchronization is a complex operation for switching generator to an electric energy system for parallel operation. Currently, the synchronization process is performed by two traditional methods: manually by human operator or by automatic devices. This operation is accountable for the possible danger to the synchronous generator integrity and to the adjacent part of the energy system. The severity of negative consequences depends on both the synchronization method chosen (ideal synchronization or self-synchronization) and on human factor. To minimize negative impact, the accelerated synchronization method for switching the generator into parallel operation is proposed. Taking into account the different operation modes of the energy system (normal or emergency) and need for rapid commissioning of generating equipment reserves, the most appropriate synchronization methods should be used. The system frequency deviation at the input of the device by 5 Hz results in the error of 0.6 %. In emergency operation, the synchronization process will be performed with the required accuracy as the error of the complex algorithm is within the acceptable range. The system solves the problem of switching to automated control in electricity generation process. Experiments on a physical model confirm that the average duration of synchronization by the accelerated method is two times lower than with accurate synchronization.
