摘要
详细分析补偿系统发生单相接地时零序电流的特点,提出利用零序电流有功分量进行接地选线的方法,并提出利用递推DFT算法实现此方法的原理及步骤。
The paper analyses the characters of zero-sequence current in detail when the single phase ground happens in the compensat-ing system and puts forward a new means to select the ground wire with power component of zero-sequence current.It also describes the principle and procedure using the recurrence DFT algorithm to achieve.
