110kV及以下电压等级智能变电站系统的过电压防护研究

防护工作在各地变电站中非常重要,当前110kV及以下电压等级智能变电站影响范围大,防护水平也有待提升。基于此,文章以110kV及以下电压等级智能变电站系统的过电压类型以及原因作为切入点,给予简述,并以此为基础,论述过电压防护措施,给出防护系统化、防护智能化等建议,最后以模拟实验方式对相关理论作系统论证,以期通过分析为后续具体工作提供必要参考。

Protection work is very important in various substations.The current 110kV and below voltage level intelligent substa tion has a wide range of influence,and the level of protection also needs to be improved.Based on this,the paper takes the over voltage type and reason of 110kV and below voltage level intelligent substation system as the breakthrough point,gives the brief in troduction.Then,taking this as the foundation,it discusses the over-voltage protection measure,and gives the protection systematiza tion,the protection intelligence and so on the suggestion.Finally,the simulation experiment is used to make a systematic demonstra tion of the relevant theory,in order to provide the necessary reference for the follow-up specific work through the analysis.
