چکیده مقاله :

به دلیل پیچیدگی شبکه‌های توزیع چگونگی انجام تعمیرات پیشگیرانه بسیار ضروری است. یکی از عوامل موثر بر بهبود عملکرد شرکت‌های توزیع وضع مقررات انگیزشی می‌باشد، که خود سبب پیچیده‌تر شدن برنامه‌ریزی تعمیرات می‌گردد. در این مقاله مسئله برنامه ریزی تعمیرات پیشگیرانه به منظور ارتقای قابلیت اطمینان در حضور عامل انگیزشی جریمه و پاداش هدف قرار داده شده است. از این رو تابع سود شرکت توزیع که شامل هزینه تعمیرات و جریمه و پاداش می‌باشد، بهینه سازی می‌گردد. در مدل انگیزشی برای سنجش عملکرد شرکت‌های توزیع، شاخصهای قابلیت اطمینان به تفکیک فیدرها مقایسه می‌گردند و در مقابل، برنامه تعمیرات نیز برای هر فیدر به‌صورت مستقل به دست می‌آید. با توجه به تفاوت علل خرابی در فیدرها ناشی از ویژگی‌ها‌ی ساختاری آن‌ها و شرایط آب و هوایی، کوچک شدن مقیاس مقایسه عملکرد از شرکتها به فیدرها، علاوه بر افزایش دقت اختصاص جریمه و پاداش سبب بیشینه‌شدن تاثیر تعمیرات و نگهداری بر سطح قابلیت اطمینان آن‌ها توام با بهینگی هزینه‌ها می‌گردد. به این منظور برای اطلاعات یک شبکه واقعی شامل ۱۹۴ فیدر پس از دسته بندی فیدرها و اعمال جریمه و پاداش، بهینه سازی سود حاصل از ارائه خدمات به روش BPSO انجام شده است. درنتیجه برنامه تعمیرات پیشگیرانه به تفکیک فیدرها برای سه دسته کلی خرابی پرتکرار یعنی خرابی پست، خرابی خطوط و برخورد شاخه درختان در یک دوره ۵ ساله به دست آمده است. نتایج بهینه سازی نشان می‌دهد که روش ارائه شده همزمان با بیشینه نمودن سود شرکت های توزیع، عملکرد آن‌ها از نظر قابلیت اطمینان را نیز ارتقا می‌دهد.

چکیده انگلیسی:

Due to the complexity of distribution networks, preventive maintenance is very important. Incentive regulation is also one of the factors influencing the performance of distribution companies, which in turn complicates maintenance planning. This paper addresses the issue of preventive maintenance planning to enhance reliability in the presence of reward and penalty as a motivational factor. Therefore, the profit function of the distribution company, which includes the cost of repairs and reward-penalty, is optimized. In the incentive model for measuring the performance, reliability indices are compared by feeders, and in contrast, the repair program is obtained for each feeder separately. Due to the different causes of feeder failure such as their structural properties and weather conditions, increasing the accuracy of performance comparison from companies to feeders, in addition to penalties and rewards assigning leads to maximise the impact of maintenance at the level of their reliability and is accompanied by cost savings. For this purpose, the information of a real network including 194 feeders is considered as primary data. After categorizing the feeders and calculating penalties and rewards, the profit from the provision of services are optimized by BPSO method. As a result, the preventive maintenance program is obtained separately for feeders for three general categories of frequent failures, which includes substation failure, line failure and tree branch collision in a period of 5 years. The optimization results show that the proposed method, while maximizing the profits of distribution companies, also improves their performance in terms of reliability.
