The DL algorithm is an improved signal processing algorithm which can accurately measure the instantaneous electrical variables such as the amplitude, phase angle, frequency and power of the fundamental and harmonic components in power disturbance. This paper briefly reviews the definition and attributes of the DL algorithm, which is introduced in detail in part 1 of the two part series, and then presents the ways to implement the DL algorithm for practical application. Several case studies using practical power disturbances are presented to prove the effectiveness of the DL algorithm.
