摘要
在电力系统中,电压互感器的使用频率不断提高,这导致场站维修工作人员不得不停用相关保护设备,造成计量电量的损失.同时,频繁的倒闸操作也大大增加了场站的运行风险.此外,电能表失压也可能对场站的经济考核造成负面影响.因此,对新能源场站母线电压互感器问题进行深入研究是迫在眉睫的任务.旨在探索电压互感器故障的原因,并制定有效的应对措施,以降低场站运行风险和电量计量损失.结合理论分析和实际案例,提出解决方案,预期结果是有效解决电压互感器故障问题,提升场站运行效率和经济效益,不仅可以为后续研究提供理论依据,也可以为电力系统实践提供有益的指导,具有重要的理论和实践意义.
Abstract
In the power system,the frequency of voltage transformers'usage continues to increase,leading to the necessity for station maintenance personnel to deactivate related protection equipment,resulting in the loss of metered electricity.Additionally,frequent reclosure operations significantly raise the operational risks at the station.Furthermore,voltage meter failures could also negatively impact the station's economic evaluation.Therefore,it is imperative to conduct an in-depth study on the issues with busbar voltage transformers at new energy stations.The purpose was to explore the causes of voltage transformer faults and develop effective response measures to reduce operational risks and metered electricity losses at stations.Combining theoretical analysis with practical cases,solutions were proposd,with the expected outcome of effectively addressing voltage transformer fault issues,improving station operational efficiency and economic benefits.The research not only provides theoretical basis,but also provides valuable guidance for practical applications in power systems,demonstrating significant theoretical and practical significance.
