基于PV曲线的低压减载配置方法

低压减载是解决电力系统电压失稳的重要手段之一。目前工程实践中多采用试凑法进行低压减载方案设计，工作量大且缺乏系统性。为此，文章结合工程实际提出了一套低压减载配置的系统性方法，该方法以保证确定的电压恢复值为目标，以PV曲线为依据。研究表明，该方法具有系统性、鲁棒性和易用性，可直接指导工程实践。

Undervoltage Load Shedding Configuration Based on PV Curve

Undervoltage load shedding is one of the important means to prevent power system voltage instability. At present the trial-and-error method is usually used in the engineering practice to design the undervoltage load shedding scheme, however, such a design way lacks of systemization and its workload is heavy. For this reason, combining with practical engineering a PV curve based systemic method to configure undervoltage load shedding devices is proposed and it is the objective of the proposed method to ensure the rated voltage restoration. Research results show that the proposed method is systemic, robust and easy to use. The objective of the proposed method is to ensure specified.
