R. Jyothsnalakshmiprasanna.rs@andhrauniversity.edu.in<p><em>This paper aims to study three Direct Torque Control (DTC) techniques for an Interior Permanent Magnet Synchronous Machine (IPMSM) using Model Reference Adaptive Control (MRAC). In the conventional DTC technique using a look-up table, gate signals are given to the Inverter that drives IPMSM. Since it is a 6-sector scheme and the operation of the minimum number of voltage vectors, undesired torque and flux ripples are created. Hence the problem of ripples is reduced by using the DTC-12sector technique, where the stator flux locus is divided into 12 each of 30degrees. Another technique of DTC is the Direct Torque Controlled (DTC)-SVM (Space Vector Modulation) technique. In the DTC-SVM technique by using Space vector pulse width Modulation, an Inverter is operated that drives IPMSM. Maximum Torque Per Ampere (MTPA) control is developed for the utilization of maximum drive efficiency. In addition, the sensor less control technique is implemented to improve the mechanical robustness of the drive and its cost-effectiveness. The sensor less technique that is used for the estimation of speed and rotor position is MRAC. By using MATLAB/Simulink the above schemes are simulated.</em></p>2023-12-04T09:54:00+00:00Copyright (c) 2023 International Journal of Electrical Power System and Technologyhttps://ecc.journalspub.info/index.php?journal=JEPST&page=article&op=view&path%5B%5D=1891A Review: The Commercial Effects of Power Factor Adjustment for Industrial Load2024-01-05T06:46:18+00:00Hare ramhareram52.eee@gmail.comShalini Goadhareram52.eee@gmail.com<p>Power is becoming increasingly vital in the current technological revolution, as the need for power in industrial and commercial loads rises. So, we must investigate the causes of control failure and advance the framework. Due to a range of electrical and power electronics demands, the power system loses efficiency, resulting in a lagging power factor, which imposes significant fines on consumers by the electricity board and pollutes the system environment. As a result, we must strengthen the power factor of the electrical system. It can be enhanced by utilizing an APFC system, which can maintain a steady high-power factor closer to unity. Because most industrial loads are inductive in nature, they use reactive power, affecting generation. Typically, less emphasis is placed on the potential negative impacts. One of the most important criteria for power system operation and design is power quality. An electrical power system that has a high uptake of commercial loads with a lot of inductances can benefit greatly from having a power factor that is close to unity as a reliable indicator of overall power quality. An electrical system with a low power factor is often less efficient, and it may also be less cost-effective for system operators and end users.</p>2024-01-02T09:39:00+00:00Copyright (c) 2024 International Journal of Electrical Power System and Technologyhttps://ecc.journalspub.info/index.php?journal=JEPST&page=article&op=view&path%5B%5D=1933Wind-Solar Cogeneration on the Grid Using Voltage-Source Converters2024-01-05T06:46:18+00:00S.

Sai Prakashrajithasaka.eee@jntugvcev.edu.in<p>The paper presents a cost-effective configuration for a Grid-Connected Wind-Photovoltaic Cogeneration system. In addition, topology provides an independent tracking of the maximum power point for both wind and solar to maximize renewable energy use. The solar is correlated with grid via Voltage Source Inverter (VSI), wind turbine based on a permanent magnet synchronous generator is correlated with the utility grid via Voltage Source Rectifier (VSR). The intermediate circuit capacitor was used for the direct connection of photovoltaic solar generator, DC/DC conversion is not required and therefore the hybrid system is simple and efficient. The detailed small-scale models for the system modules are developed to illustrate the overall stability. The impact of disturbances in the supply network on the performance of the system is examined. The simulation results under different operating conditions are presented to validate the stability of the proposed topology by using MATLAB/Simulink.</p>2024-01-02T10:47:22+00:00Copyright (c) 2024 International Journal of Electrical Power System and Technologyhttps://ecc.journalspub.info/index.php?journal=JEPST&page=article&op=view&path%5B%5D=1936Voltage stability analysis in Power system using PMUs and UPFC2024-01-05T06:46:18+00:00Suresh Babu Palepusureshram48@gmail.comM. Damodar Reddysureshram48@gmail.com<p><em>Voltage instability has drawn the attention of both researchers and utilities due to the numerous system outages that have been linked to it over the past several decades in many places of universe. The improvement of synchrophasor techniques enables real-time monitoring and management of the network’s stability in voltage concern. This study recommends employing strategically placed synchrophasor measuring units (PMUs) to measure the margin of voltage-stability on-line and control it with a unified power flow controller (UPFC). At the critical bus, UPFC has been placed in accordance with the least magnetic and active power load ability for most of the line outages. UPFC provides actual and reactive power to the system according to the variation between the base voltage and its node value. Node voltages are calculated using PMU measurements at regular intervals, and as needed, actual and magnetic power is subsequently delivered to the system online. Continuous checks are made of the wider voltage stability margin caused by the UPFC's injection of reactive and actual power. The efficiency of the proposed method for on-line management and monitoring of voltage-stability margin (VSM) has been demonstrated using simulations on the IEEE 14-bus system and the New England 39-bus system.</em></p>2024-01-05T06:45:51+00:00Copyright (c) 2024 International Journal of Electrical Power System and Technology
