APPLICATION OF PERFORMANCE OBJECTIVE PRODUCTIVITY (P.O.P) THROUGH ERGONOMICS APPROACH [pp 01-11]
Dr. Vinay kumar Chaudhary
ABSTRACT- Ergonomics (from the Greek word ergon meaning work, and nomoi meaning natural laws), is the science of enhancing the design of products to optimize them for human use. Human dynamics , such as height, weight, and proportions are taken into consideration , as well as factors such as human hearing, vision, temperature preferences, and so on. Ergonomics is sometimes known as human engineering. In the era of Digital Explosion, Computers and related products, such as computer tables and chairs, are dominantly the stress point of ergonomic….
A REVIEW ON EFFICIENT METHOD FOR DETECTION OF PARTIAL SHADING AND MAXIMUM POWER POINT TRACKING ALGORITHM OF PV SYSTEM [pp 12-16]
Raja Kumar, Santosh Kumar
Abstract-In this study Maximum Power Point Tracking (MPPT) is applied to the Photovoltaic (PV) system to harvest the maximum power output. Maximum Power Point Tracker in a Photovoltaic system allows to maximize the energy drawn from the connected photovoltaic modules. In the partial shade conditions there can be more than one maximum point in photovoltaic output power curve. The solution for this situation is a maximum power point tracker algorithm, which finds the global maximum. In literature, there is a large number of studies on maximum power….
A REVIEW ON EFFICIENT FAULT DIAGNOSIS SCHEME FOR PV SYSTEM USING MACHINE LEARNING TECHNIQUES IN THE DC SIDE [pp 17-21]
Upendra Sah, Santosh Kumar
Abstract- A PV system converts the solar energy into electrical energy, and this energy is either stored in a battery bank in a standalone system or transmitted to the grid through grid interfacing power electronic converters. PV fault protection/detection and isolation devices of multiple kinds are installed in a PV station to isolate the PV converters/grid from the PV array during any fault in the PV system. Although, the rest of the power processing or storage units are isolated from the faulty PV array, the solar cells remain active and may produce significant current flow within the modules that may result in damages even catastrophic fire…..
A REVIEW ON PROBABILISTIC MODELING BASED FORECASTING APPROACH TO PREDICT FUTURE PHOTOVOLTAIC POWER GENERATION [pp 22-27]
Subrat Kumar, Santosh Kumar
Abstract: The ability to accurately forecast power generation from renewable sources is nowadays recognized as a fundamental skill to improve the operation of power systems. The performance of the various forecast models are affected by many elements of uncertainties, and in the opinion of the authors it is not always clear how single choices (e.g., the choice of a specific prediction methodology over another) or different factors (e.g., meteorological forecasting errors) contribute to the final prediction error (i.e., in terms of predicted vs. actual power generation). Actually, the vast majority of the current related works….
DESIGN & ANALYSIS ON BRAKE CALIPER BY USING DIFFERENT MATERIALS THROUGH ANSYS [pp 28-34]
Ashish Ranjan Bhagwat, Sohail Bux
ABSTRACT- The disc brake rotor is a rotating device. Braking is a process which converts the kinetic energy of the vehicle into mechanical energy which must be dissipated in the form of heat. This project presents the analysis of the contact pressure distributions at the disc interfaces using a detailed 3 dimensional finite element model of a real car disc brake rotor . Finite element (FE) models of the brake-disc rotor are created using CATIAV5R20 and simulated using ANSYS 19.2 which is based on the finite element method (FEM). It is also investigates different levels in…..
A REVIEW ON COMPOSITE LEAF SPRING FOR MEDIUM HEAVY VEHICLE [pp 35-39]
Shiv Nandan Chourasia, Sunil Shukla, Arun Patel
ABSTRACT- A leaf spring is a basic type of spring, generally utilized for the suspension in wheeled vehicles. Leaf Springs are long also, thin plates connected to the edge of a trailer that rest above or beneath the trailer’s pivot. There are mono leaf springs, or single-leaf springs, that comprise of basically one plate of spring steel. These are normally thick in the center and tighten out toward the end, and they don’t normally offer a lot of solidarity and suspension for towed vehicles. Drivers hoping to tow heavier burdens commonly use multi leaf springs….
A REVIEW ON MICROGRID PROTECTION TECHNIQUE [pp 40-44]
Mamta Narware, Laxman Solankee
ABSTRACT- In order to analyze the challenges and solutions provided in the microgrid protection, this paper presents the review of protection algorithms proposed in the literature. The present review work has been oriented to provide the idea of protection strategies adopted in the past and their effectiveness in providing the protection to microgrid with reliability. Various efficient protection approaches have been discussed and compared to examine the effectiveness of them in providing the suitable protection against the common issues and challenges. Furthermore, the review is also oriented to describe the various challenges associated in the development of appropriate protection technique related to the mode of operation, nature of DERs and their dynamic profile. The comparison results showed….
