Opis:
Sustainable development of an area is highly dependable on reliable electrical energy supply. Due to the depletion of fossil fuels, and the contamination of the environment due to the generation of energy from primary energy sources, the energy sector is reforming and shifting towards a new era where renewable energy sources will become the primary focus of attention. At present, energy researchers and government organizations are interested in a distributed generation system using local renewable energy sources to electrify the rural areas situated far away from our mainland. Here, a biomass-based power supply system is being analyzed and compared with other potential power supply systems for Sagar Island. Sagar Island is the world’s largest river-based island situated in the Sundarban deltaic complex, where the potential of biomass is huge due to the availability of natural forests, barren coastal areas full of weeds, agricultural by-products, cattle manure and waste materials from other sources. Here, an attempt has been made to provide sustainable electrical energy to the rural areas of the isolated Sagar Island for the sustainable development of the local people. This was done by means of using biomass and a fuel cell based electricity generation system.

Opis:
Synchronization in the energy generated by renewable energy sources is one of the significant issue associated with the converter used in the system module. The presented paper concentrates on the design aspect of a PV and wind power input to a DC-DC converter which can be practically useful in hybrid renewable energy power systems. In this regard, the proposed converter can be utilized to obtain a smooth regulated output voltage from the given input renewable energy power sources. The proposed converter can be efficiently work under critical conditions having very few ripple in current waveform of input or output. A major advantage with this type of converter is the simple circuit with respect to the conventional converters in some critical situations. At the end, the result based on the simulation exercise and various experiments, performance of the converter in different situations is presented so that the efficiency of the designed converter arrangement is accepted.

Opis:
A novel circuit topology of modified switched boost high frequency hybrid resonant inverter fitted induction heating equipment is presented in this paper for efficient induction heating. Recently, induction heating technique is becoming very popular for both domestic and industrial purposes because of its high energy efficiency and controllability. Generally in induction heating, a high frequency alternating magnetic field is required to induce the eddy currents in the work piece. High frequency resonant inverters are incorporated in induction heating equipment which produce a high frequency alternating magnetic field surrounding the coil. Previously this high frequency alternating magnetic field was produced by voltage source inverters. But VSIs have several demerits. So, in this paper, a new scheme of modified switched boost high frequency hybrid resonant inverter fitted induction heating equipment has been depicted which enhances the energy efficiency and controllability and the same is validated by PSIM.

Opis:
In this study, a new circuit topology using a Z-source resonant inverter (ZSRI) for high power applications in large-air-gap contactless power transfer (CPT) systems, has been investigated. The main shortcoming of a large-air-gap CPT system is the poor power transfer efficiency due to low magnetic coupling. In order to minimize this shortcoming and to improve the overall performance of the system by boosting the power transfer capability, in this paper a CPT system with the newly developed circuit topology using high frequency Z-source resonant inverter has been proposed. Using the newly developed circuit topology for the CPT system, it has been observed that the overall performance of the system has been improved to a reasonable level with a purely sinusoidal resonant current flowing through the primary side. Therefore, no harmonics will be injected into the source. The proposed CPT system with an air gap of 16 cm and a misalignment of 3 cm has been simulated using the Maxwell finite element tool and Simplorer circuit simulation software for an output power of 2 kW.

Opis:
Investigations were carried out in 2010 to determine the influence of abiotic factors on the incidence of the two spotted spider mite; Tetranychus urticae Koch and to determine the influence of pesticides on orchid flower production. Initially, in January, the mite population was very low (1.0 mite/10 cm2 leaf area). The population gradually increased and peaked to 22.98 mites/10 cm2 leaf area in the first fortnight of May along with the rise in temperature and sunshine. Then, the population declined to a low level of 3.43 mites/10 cm2 leaf area in the first fortnight of December. Maximum and minimum temperatures had a significant positive correlation and sunshine had a non-significant positive correlation, whereas relative humidity and rainfall had a non-significant negative correlation with the mite population. Infestation of the two spotted spider mite was more severe in untreated conditions in comparison to the treated ones. The difference was due to various abiotic factors and natural pest infestation occurrence which drastically affected the flower quality and yield. In unprotected conditions, the number of flower spikes/plant (1.90±0.44 spikes), number of flowers/spike (7.35±1.04 flowers), spike length (42.59±5.69 cm), flower spike diameter (5.26±0.66 mm), and flower size (6.27±0.86 cm) was very low. In protected conditions, flower quality and yield were superior than in unprotected conditions i.e. number of flower spike/plant (2.92±0.57 spikes), number of flowers/spike (11.78±1.16 flowers), spike length (57.59±7.35 cm), diameter of flower spikes (9.09±1.01 mm), and flower size (6.73±1.16 cm).
