A New Method for Considering Distribution Systems in Voltage Stability Studies
In methods presented to calculate the voltage collapse point, the transmission system is usually the only part of the power system that is completely modeled. Distribution systems are often replaced by aggregate load models because the use of the detailed model of distribution systems in voltage stability analysis not only increases the computation time, but also decreases the probability of co...
متن کاملcoordination of protective schemes in distribution and subtransmission systems including distributed generation
نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...

متن کاملEquivalent Evaluation Method of Three-Phase Voltage Flicker Evaluation
Owing to violent and stochastic load fluctuation, different voltage flicker components may exist in different phases. Traditionally, the averages of three single-phase values are given. However, in this paper, it wants to investigate a fast computation algorithm to calculate directly the equivalent three-phase values. After the voltage waveforms of three phases are recorded, the voltage flicker...
متن کاملVoltage Sag in Distribution Systems- A review and comparative study (Reasons, Characteristics, Compensations and Detection)
By quick technological advancements in industrial control processes, major industries demand higher power quality. According to IEEE 1159-1995 standard, any problems in voltage, current or frequency that lead to the error or malfunctions in electrical equipment are considered as a power quality problem. Among the power quality phenomena, voltage sag has been an important problem for power sys...
