Study of a STATCOM Application for Voltage Stability Evaluated S.Rajasekqar, Assoc Professor & HOD, NIST, Nagole, Hyderabad Abstract: In this paper voltage stability is evaluated b-v both dynamic P V curves and time-domain simulations, considering the combined dynamic control effects of a static compensator (SZ4TCOh!) and transformer on-load-taps (OLT). The studied system is heavily loaded at hvo locations and an 80 Mvar STA TCOM is connected to improve the voltage stability of entire s~stem for
play great role in power systems planning and operation. Nowadays, power systems are being performed closer to their steadiness limits due to economic and environmental constrains. Maintaining a fixed and secure operation of power system is hence a very vital and challenging issue. Therefore, it is highly suggested to take care of voltage stability especially in high enhanced networks as a consequence of heavier loading. Many researchers study the power system voltage stability from different points
Generator Protection Subsynchronous Resonance Sokhom Sim Department of Electrical Engineering California State University, Long Beach Long Beach, CA 90840-8303 ericsokhomsim0@gmail.com Abstract-the transmission lines are complex systems and the power generation sources are generally far away from the distributing center. The transmission lines congesting or overloading are always a challenge for utilities protection engineers. As a result, a series compensating capacitors are being used to alleviate
Abstract— Voltage instability is one of the major power system problems which have appeared since the existence of the power systems. This paper investigates the performance of Recurrent Neural Networks (RNN) in voltage instability early prediction. Voltage instability early detection is necessary for avoiding voltage collapse which can lead to power system fast breakdown. In this research, the bus voltage phase is considered as the main factor of power system voltage instability early detection. Voltage
(GCI) are widely used to feed power from renewable energy distributed generators into smarter grids. Repetitive control (RC) enables such inverters to inject high quality fundamental-frequency sinusoidal currents into the grid. However, digital RC which can get approximately no tracking error of any periodic signal in steady-state whose period is known, cannot exactly track or reject periodic signal of frequency variations. Thus digital RC would lead to a significant power quality degradation of GCIs

REDDY, ASST.PROF, BRILLIANT GROUP OF INSTITUTIONS, HYD ABSTRACT: -- In this a fuzzy logic control technique has been proposed for power quality improvement by using UPQC The UPQC is controlled to regulate the WF terminal voltage, and to mitigate voltage fluctuations at the point of common coupling (PCC), caused by system load changes and pulsating WF generated power, respectively. In order to reduce the voltage fluctuations that may cause “flicker”, and improve WF terminal voltage regulation, several

laws and regulations, communication efficiency, interference and transmission cost, this study proposes a wireless ARM-based automatic meter reading and control system (WAMRCS). The WAMRCS uses sampling circuits and A/D convertor to transfer analog signal of voltage and current into digital data. The digital data then send to embedded system to compute power parameters. This embedded system will send power parameters to regional monitoring and control center of utility company via wireless module
