摘要
对于无法实现自动电压控制调试且拥有超长架空线路的新能源场站,运行人员只能依赖经验进行估算、调整无功补偿,这不仅难以保障设备稳定运行,且偏低的功率因数还会引发电网考核。针对这一难题,以某110 kV及对侧330 kV变电站为研究对象,建立基于对无功数据进行计算、分析而形成的一种无功功率手动调节模型。结果表明:在所建立模型的计算方式下,变电站的月功率因数成功提升,显著改善了无功功率的管理和电能质量。这一成果不仅为变电站的正常运行提供了保障,避免被电网考核,也为电力系统的稳定性和经济性作出了贡献。
As for the renewable energy stations unavailable to implement the automatic commissioning of voltage control and equipped with ultra-long overhead lines,operators can only rely on their experience to estimate and adjust the reactive power compensation,which is not only available to ensure the stable operation of equipment,but also leads to low power factors that might trigger grid penalties.To address this challenge,a 110 kV substation and its 330 kV counterpart are studied to develop a manual reactive power regulation model based on the calculation and analysis of reactive power data.Results show that the proposed calculation approach of the model successfully improves the monthly power factor,significantly enhancing the reactive power management and power quality.This achievement not only ensures the normal operation of substations to prevent grid penalties,but also contributes to the stability and economics of power systems.
