finally this method is realized in microprocessor based busbar protection, the result of a lot of experiments indicates that this protection can reliably avoid misfunction of the busbar protection, and when the fault is developed, the fault can be rapidly eliminated by the protection 最后,在微机保护装置上编程实现。大量试验表明谐波制动判据具有很好的抗ta饱和能力,而且当故障由母线区外转至区内时,判据能够迅速开放。
