يهدف هذا البحث إلى تحديد مؤشر الموثوقية لأنظمة الطاقة الكهربائية بشكل دقيق و بدون استخدام الكثير من المدخلات و عمليات المعالجة, و ذلك للاستفادة من النتائج في مرحلة تخطيط و تصميم الشبكات الكهربائية لما لها من أهمية فنية و اقتصادية كبيرة في الاختيار الأمثل لعناصر الشبكة و طرق توصيلها. و قد اعتمدنا في هذا البحث على استخدام مفهوم شبكات بتري لتمثيل الشبكات الكهربائية المدروسة و من ثم محاكاة المخطط المكافئ باستخدام برنامج GRIF لحساب درجة موثوقية عمل النظام و عناصره. يتضمن هذا البحث مقارنة منهجية الطريقة المقترحة المعتمدة على مفهوم بتري مع شبكة مرجعية عالمية و من ثم تطبيقها على شبكة كهربائية محلية و مناقشة نتائجها حيث تبين بالنتائج فعالية شبكات بتري في حساب الموثوقية بأفضل طرق المحاكاة.
The purpose of this study is to define the reliability index for electrical power systems specifically and without using alot of data and treating processes. Results of this study is useful in electrical networks planning and design because of its technical and economical importance in the optimal choosing of networks elements and connections. In this research we use petri nets concept to represent electrical nets under studying then simulate the equivalent chart on GRIF program to find reliability degree for the system and its elements. This research includes comparing the suggested methodology to a reference net and then apply this method on electrical local network to discuss the results. It has been proved that petri nets are effective in reliability calculations with the best of simulation methods.

The study seeks to determine the real time in electrical power system, which consists of
generating, transmitting and distributing equipment by using redistributing active power of
electrical generators in order to organizing the overload operation
of electrical power
transmission line loading in such case that the spare loads of electrical station are not
covering the important and necessary loads at failures.
The most of laws related to electrical power systems design indicated to proper ratio of
real time of electrical power system equipment along with characteristics of probability
distributed functions in addition to statistics methods which give a high possibility to
reduce the real time of considered loads; so; this leads to the requested solutions which
reduce the damage of failures at any time.
In this paper, we will design a Fuzzy Smith Predictor (FSP),
then we will model, simulate and analyze it using colored Fuzzy Petri
networks, then we will compare it with a conventional proportional
integral controller.
The main objective of this
research is to reduce the delay time
of the wind turbine system and to increase its reliability, in the other
side, to improve the response and stability of the operating point of
the mechanical energy and reduce vibration caused by the delay time
in the system.
This paper addresses failure-prone
production line with limited buffers. Each machine is subject to
either time-dependent failures or operation dependent failures.
This research presents software programs that have been designed in order to evaluate the reliability in
electrical distribution networks, by calculating the reliability indices for 20 kV distribution feeders. It is
the first study in this field for the distribution network in Syria.
First of all, the mathematical models of reliability have been presented.
This paper provides algebraic representation of Petri Nets model, taking
advantage that the releasing principle of Petri Nets depends on reduction process
of Monoiad of the commutative natural numbers.
(In conclusion) Finally, we provided a theore
m that explains how to make use of
algebraic properties, to simulate Petri Nets algebraically and identify the results
we will get after releasing a series of Petri Nets' transitions.
