大型水电机组应具备一次调频功能并能主动投入,保证电网和机组的安全稳定运行。本文讲述了水电机组一次调频的原理、一次调频的实现与试验、一次调频与水电站监控系统的配合。此外,结合试验文章阐述了电网对机组一次调频的技术要求。 Large hydropower units should have a frequency control function and can take the initiative to ensure the safe and stable operation of power grids and units. This paper describes the principle of a hydropower unit FM, a FM implementation and testing, a FM and hydropower monitoring system with. In addition, combined with the test article describes the technical requirements of the primary frequency of the unit.
