摘要
电网供电频率是评价电能质量的重要指标,频率超限会严重影响发电、电网、用户的安全和经济效益。研究和完善入网燃气-蒸汽联合循环发电机组的一次调频系统,对于提高电网稳定性至关重要。该文介绍了燃气-蒸汽联合循环发电机组的特点,并以M701F4型"二拖一"燃气-蒸汽联合循环发电机组为例,介绍了该类型机组一次调频控制系统及控制方式,为同类型机组一次调频提供参考。
The power grid frequency is an important indicator of the power quality,frequency outside would seriously affect the power generation ,power grid,user＇s security and economic benefits. Research and improve the primary frequency performance of gas-steam combined cycle power units which connect to the grid is essential for improving grid stability. This article describes the characteristics of gas-steam combined cycle power unit,describes the control system and control mode of primary frequency to the M701F4 type ＂two-pull-one＂ gas-steam combined cycle power unit as an example,and provides a reference for the same unit of primary frequency.
