چکیده
High-voltage direct current (HVDC) technology based on Line Commutated Converter (LCC) is widely used in modern power systems due to its numerous benefits. However, as a typical electronic device, LCC-HVDC has caused significant changes the dynamic behavior of largely replaced conventional supplies systems. The interactions among sending-terminal and receiving-terminal system become stronger have some stability issues, but mechanism behind this yet be fully revealed. In order analyze LCC-HVDC, small-signal model modular HSS modeling proposed Harmonic State Space (HSS) theory. Comparison time-domain response with detailed switching shows that can well reflect model. Based model, influence controller’s parameters analyzed, are investigated. Analytical results demonstrate there exists which an system.

Dynamic Harmonic Modeling and Analysis of VSC-HVDC Systems
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...
متن کاملSmall-signal Modeling of Lcc Resonant Converter
The small-signal modeling technique based on the extended describing function concept is applied to LCC resonant converters. The analytical model developed includes both frequency control and phase-shift control. The small-signal equivalent circuit models are also derived and implemented in PSPICE. The models are in good agreement with the measurement data. 1. INTRODUCTION An LCC resonant conve...
متن کاملStructural analysis based on state-space modeling.
A new method has been developed to compute the probability that each amino acid in a protein sequence is in a particular secondary structural element. Each of these probabilities is computed using the entire sequence and a set of predefined structural class models. This set of structural classes is patterned after Jane Richardson's taxonomy for the domains of globular proteins. For each structu...
متن کاملImpedance Analysis of Modular Multilevel Converter Based on Harmonic State-Space Modeling Method
The small-signal impedance modeling of modular multilevel converter (MMC) is the key for analyzing resonance and stability of MMC-based ac power electronics systems. MMC is a converter system with a typical multi-frequency response due to its significant steady-state harmonic components in the arm currents, capacitor voltages, and control signals. Therefore, traditional small-signal modeling me...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
