Harmonic Assessment in Jordanian Power Grid Based on Load Type Classification
Author:
Abstract: The demand of efficient power converters lead to the proliferation of nonlinear loads in the power system. These nonlinear loads cause a serious problems that affect the power quality in both transmission and distribution systems. One of the major Power quality problems is Harmonic pollution. Understanding and quantifying the harmonics level in electrical power grid are crucial before proposing any successful method for mitigating harmonics problems in the grid. In this paper, the harmonics level in Jordan Low-Voltage Electrical Power Grid (JLVEPG) is investigated. The loads are divided into five categories: : (i) industrial loads, (ii) commercial loads, (iii) hospital loads, (iv) residential loads, and (v) office loads. Assuming each category will inject similar harmonics in the grid, which will facilitate harmonic assessment in the power system. Also, this categorization of the loads will make proposing harmonic mitigation solutions much easier. A field measurement for the major electrical units (Voltages, currents, and power) in JLVEPG is carried out for different locations in multiple cities. These measurements are followed by data analysis techniques in order to identify the total harmonic distortion (THD), the most dominant harmonic in each load category, and the harmonic power as a ratio to the active power.
