Development of Digital Device for Automatic Switching Into Network of Educational Power Station Generators

Abstract

The process of power generation is accompanied by the parallel operation of synchronous generators of the power station on the bus of the generator or high voltage. This process is very dynamic and subject to influencing external factors every second. Synchronization is a set of actions to turn on synchronous generators for parallel operation with other synchronously rotating generators of a power plant or an electric power system [1] . That is, the synchronization operation is an integral part of the process under consideration. Synchronization is a complex and responsible process, since during its implementation there is a danger of damage and violation to the integrity of the unit. Currently, synchronization is carried out both manually by staff and when using automatic control. However, in order to avoid the consequences of improper inclusion of the generators, when performing synchronization, the influence of the human factor should be eliminated as much as possible. To ensure the optimal operation mode of the station units, as well as change their states: start, shutdown, switching on for parallel operation, it is necessary to automate the power generation process and switch to automatic control. The synchronization operation must be semi-automatic or fully automatic. Devices for automatic synchronization process are called synchronizers.
