When the signal sources have different cycle frequencies, a method to estimate the optimal time lag is presented. It solves the severe problem that the conventional Cyclic MUSIC requires knowing the optimal time lag in computing the cyclic correlation matrix. A method of two-step search for DOA estimation by employing an interleaving technique and a Joint Estimation Strategy is developed to overcome the inadequency of signal sources with the same cycle frequency having no optimal time lag.

Another method is fault location algorithm using short data window in the calculation. Because the saturation time of current-transformer lag behind the instant of fault occurrence, it is possible to determine the fault location utilizing the sampling data prior to the saturation. The simulations showed that both of the methods can solve the problem of current-transformer saturation.
