Abstract

Estimation of power system parameters for generation of reference signal is one of the most essential requirements for switching action of the converters. This paper explores the measurement of power system harmonic components with a newly developed Recursive Newton Type algorithm. In the developed algorithm, first the parameters will be updated using Jacobian and Co-variance matrices. Implementation of the co-variance matrix in the proposed algorithm results in fast convergence, minimum computational and settling time, better accuracy of tracking the signals etc. The effect of the developed algorithm is observed in a power system signal through simulations. Effectiveness of the developed algorithm is also examined using Arduino micro-controller. A comparative analysis is made between the Newton Type Algorithm (NTA) and Improved Newton type algorithm to prove the effectiveness of the developed one.
