企业配电网电压跌落原因分析及控制策略

Reason Analysis and Control Strategies on Voltage Dip of Corporate Distribution Network

文章以一起电网短路故障引起电压跌落事故为例,分别从供电运行方式、继电保护整定、中低压电网抗晃电能力等方面展开论述,分析电压跌落引起用电设备跳车的原因,并提出相应的控制措施以减少事故带来的经济损失。

In this paper,the operation mode of power supply,protective relaying setting and ability of anti-interference electricity for medium and low voltage power network are discussed,the causes for tripping of electric equipment caused by voltage dip are analyzed as well as the corresponding control measures are proposed to reduce the economic losses caused by accidents by taking an accident of voltage dip caused by the fault of short circuit of power network as an example.
