Application of Automatic Device for Generator Connection to the Network by Method of 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. A novel system eliminating human factor is developed. The synchronization system is a digital device operating as a subsystem for a microprocessor–based emergency automation complex. The system solves the problem of switching to automated control in electricity generation process.
