电压作为衡量电能质量的指标之一,备受关注.通过分析对比,得出有载调压继电器保护动作的准确率将直接影响电网电压质量,并进一步研究得出,提高有载调压保护动作准确率的方法在于减小继电器电压采集量的偏差,需由人、机、料、法、环等方面来实现.由于研究分析都来自于变电站内现场实际,将对实际工作具有重要的指导意义.
The Method to Improve the Operation Accuracy of On-Load Voltage Regulating Relay
Voltage is one of the indicators to measuring power quality,and is always been focused on by researchers.The operation accuracy of on-load voltage regulating relay will affect voltage quality of the power grid directly by analyzing.Through the analyses we can also find that reducing the deviation of collection in relay can improve the operation accuracy of on-load voltage regulating,which can be achieved by some aspects like people,machine,material,method and environment.Because all the researches are based on actual data,the conclusion of this paper has a important guiding significance.
