摘要
由于电网组成机构的变化,对电网的稳定性也提出了更高的要求,电网频率直接影响着供电质量。一次调频作为电力系统中维持功率供需平衡的重要措施,是保证电力系统频率稳定的主要途径,因此优化控制方式,可以提升供电质量,同时也是机组并网安评的重要指标。本文主要分析1000 MW超超临界火电机组一次调频原理,识别一次调频重要参数,以提升火电机组运行效率为目标,探索科学的一次调频控制与应用策略,避免机组陷入故障,优化机组一次调频性能,以此来实现保证机组负荷满足电网需求。
Due to changes in the composition of the power grid,higher requirements for grid stability have been imposed,and grid frequency directly affects power supply quality.Primary frequency regulation,as an important measure in maintaining power balance in the power system,is a key approach to ensuring the stability of power system frequency.Therefore,optimizing control methods can improve power supply quality and is also an important indicator for the grid connection safety assessment of units.This paper mainly analyzes the primary frequency regulation principles of 1000 MW ultra-supercritical thermal power unit,identifies crucial parameters for primary frequency regulation,and aims to improve the operational efficiency of the thermal power unit.It explores scientific primary frequency control and application strategies to prevent unit failures,optimize primary frequency regulation performance,and ensure that the unit load meets the requirements of the power grid.
