Abstract

A new quadratic voltage index based on power flow equations is proposed in this paper. The index supervises the power quality of a system, through predicting voltage sags. The voltage sag is caused by an increase in reactive demand due to induction motor starting. The index has been tested for a range of X/R ratios and various loading levels. Mathematical and simulation results demonstrate the effectiveness and applicability of the proposed index for the applications

一种新的二次型电压指标的数学发展、研究与仿真
本文提出了一种新的基于潮流方程的二次型电压指标。该指标通过预测电压跌落来监督系统的电能质量。电压暂降是由于感应电动机启动时无功需求增加造成的。该指数已在一系列X/R比率和各种负载水平下进行了测试。数学和仿真结果验证了该指标在实际应用中的有效性和适用性
