大型汽轮发电机进相运行在线自动控制装置

On－Iine Auto－control Device for Large Turbo Generator in Leading Phase Operation

介绍大型汽轮发电机进相运行中受到的限制条件，提出进相运行在线自动控制装置。该装置试验及运行实践表明，在发电机进相运行时，它能有效地自动控制发电机进相深度，人为误操作时，装置也能保证发电机不失稳，使厂用电电压和定子电流在要求值内，提高机组运行可靠性。

 This article introduces the run qualification of large turbo generator in leading phase operation．The design of on－line leading phase auto－control device is proposed and put into practice． It uses the computer for data processing． The test and practice have proved that the device can control the range of leading phase automatically when the generator is in leading phase． Even the man－fault is taken place it assures also that generator is not losing synchronism and voltage of power plant is practicable．
