Title:
ターボ機関の発電機を電力グリッドに同期させる方法
Document Type and Number:
Japanese Patent JP5856736
Kind Code:
B2
Abstract:
Methof of synchronizing a turbomachine generator to an electrical grid in order to match the generator (145) and grid (155) voltages before the powerplant machine (100) reaches the grid matching speed during the start-up process. A predictive algorithm (365) is provided, or the like, to control the acceleration rate of the powerplant machine (100) to target a particular phase angle differential between the powerplant machine (100) and the grid (155) when the powerplant machine (100) reaches the grid matching speed. The phase angle difference may be targeted such that a generator breaker may be closed immediately after the powerplant machine (100) accelerates beyond the grid matching speed. This may avoid the generator (145) experiencing a phase angle differential, which may add to the power transient associated with the generator breaker closure.
