چکیده مقاله :
در این مقاله روش جدیدی برای تشخیص بارهای تولیدکننده میان‌هارمونیک در سیستم قدرت و همچنین تعیین سهم هر یک از این بارها در تولید میان‌هارمونیک جريان در نقطه اتصال مشترک ارائه شده است. اساس این روش بر پایه روش جمع آثار و تصویر می‌باشد که به مدار معادل نورتن بارها و شبکه نیاز دارد. همچنین در روش پیشنهادی، از نرون خطی وفقی دومرحله‌ای برای تعیین مؤلفه‌های میان‌هارمونیک سیگنال استفاده شده است. کارایی روش پیشنهادی به کمک شبیه‌سازی در محيط نرم‌افزار MATLAB/SIMULINK نشان داده شده است. نتایج شبیه‌سازی مؤید قابلیت روش فوق در جایابی منابع میان‌هارمونیک و تعیین سهم آنها می‌باشد.
In this paper a new method for identification of interharmonic producing loads in a power system is proposed which is capable of evaluating the contribution of each individual load in the point of common coupling. This method is based on using the superposition and projection method which needs the norton equivalent circuit of loads and supply network. Also in the proposed method, a two-stage adaptive linear neuron is used for determining the interharmonic components of a signal. The effectiveness of the proposed method has been shown through simulation studies in the MATLAB/SIMULINK software. The simulation results show the capability of the proposed method for identification and contribution evaluation of interharmonic sources in a power system.
