9.1保护的种类及其整定值的计算根据其变化会引起保护装置动作的数值(动作参数)不同,保护可分为:反应电流数值的过电流保护,反应电压数值的过电压保护,反应直流线路电流增长速度的保护,反应电流稳定值增量的保护,反应被保护线路电阻的距离保护,反应交流电压波形的保护,反应交流电流分量比的保护等(对保护装置的基本要求叙述在第二卷20内)。
9.1 Types of Protection and Calculation of Its Setting Value According to the change of the value (action parameter) of the protection device, the protection can be divided into: overcurrent protection of reactive current value, overvoltage protection of reactive voltage value, reactive DC link The current growth rate of the protection of the incremental protection of the reaction current, the reaction is protected line resistance distance protection, the reaction of the AC voltage waveform protection, reactive AC current component ratio protection (the basic requirements for protection described in the second Volume 20).
