二次电压回路中的风险和改进
|
摘要
二次电压回路是变电站内二次系统中的重要组成部分,其失压会对保护装置的正确动作、自动化系统的遥测、AVC系统的无功调节等造成严重影响。文中针对电压回路失压给常见的保护装置的影响,结合二次电压回路原理,探讨了二次电压失压的风险点,并提出了相应的改进方法。
Secondary voltage loop is an important part of secondary system in substation.Loss of voltage in secondary voltage loop will seriously affect the correct operation of protection device,remote measurement of automation system and reactive power regulation of AVC system.In view of the influence of voltage circuit voltage loss on common protective devices,combined with the principle of secondary voltage circuit,the risk points of secondary voltage voltagevoltage loss were discussed,and the corresponding improvement methods were put forward.
