This has resulted in significant improvements in industrial energy efficiency, resulting in reduced emissions and resource waste. Indian mine ventilation fans were discovered to be energy guzzlers, paving the way for more efficient driving techniques. A thorough investigation of cost savings, energy savings, and pollution reductions associated with different airflow scenarios utilizing Tandsi underground coal mine ventilation networks were conducted. Two applications of ventilation-on-demand were investigated: dynamic and steady-speed reduction. Economic feasibility suggests that variable speed drives operating at medium voltage (3.3 kV) may be utilized in ventilation-on-demand systems. With the adoption of ventilation-on-demand solutions, a total yearly electrical energy savings of 1070618 kWh might be accomplished. The estimated cost savings are 119588 US $, with a payback period of seven months on average. Emissions of greenhouse gases have been reduced by around 37% annually. A variable speed drive operating at medium voltage (3.3 kV) may be placed on the Tandsi mine ventilation fan to improve efficiency and decrease emissions. These audits identify underutilized resources that may be used to increase mining sustainability and profitability.

The transformer is a very important and critical component of power system. There is a need of proper maintenance and regular diagnosis of incipient fault within transformer oil. The main cause of transformer failure is ageing, deterioration and damage of insulating material. When insulating material is subjected to any incipient fault, combustible gases are generated. These combustible gases are known as key gases. By analysing these gases transformer fault can be detected. This paper represents a review of different DGA methods. The existing DGA diagnostic method consists of mainly Key Gas method, Ratio method (Rogers and Doernenburg and I.E.C. ratio) and Percentage Gas method (Duval triangle).

The utilization of the difference gap between the electrodes allow the system to reduce the applied voltage of the HVDC power supply, while fulfilling the requirements for effective liquid food sterilization. Thus it can reduce power consumption and will reduce cost. In this paper, the CHMI circuit has been simulated using MATLAB/Simulink and the distance of the electrodes gap has been simulated using Quickfield simulation software. Peak output voltage 1.2 kV, 2.4 kV and 6 kV with gap distance 0.1 cm, 0.2 cm and 0.5 cm respectively has been obtained in which the values can produce electric field strength of up to 12 kV/cm. All of the specifications meet the requirements for liquid food sterilization, particularly inactivate saccharomyces cerevisiae spoilage microorganisms in pineapple juice.

These loads adversely affect the power quality of the system. If not rectified at times they may distort the sine wave at source side. This paper presents a power quality conditioner which is designed using multi-level inverter (MLI). The advantage that the proposed MLI has over conventional one is that it requires less number of components as compared to the conventional. Also it improves the utility profile by improving harmonic content at output side. The proposed MLI based Unified power Quality Conditioner (UPQC) improves the grid profile at non-linear loading by prohibiting the propagation of high content harmonic load current at source side. The proposed topology has inherent active filtering capability by virtue of which there has been seen a good mitigation of power quality issues at point of common coupling. Comparative analysis of the proposed topology with the conventional MLI is also presented. The c...

By selecting the total in-plant generation, spinning reserve, total plant load and rate of change of frequency as the input neurons of the ANN, the minimum amount of load shedding is determined to maintain in-plant load-generation equilibrium and to ensure continuity of power supply to critical loads of the plant. The comparison of under frequency relay based load shedding and ANN based adaptive load shedding is also preformed to evaluate effectiveness of the ANN based Load Shedding. The system frequency response for deferent generation-load scenarios is also determined. The industrial cogeneration is simulated on ETAP software and transient stability is analyzed by considering various contingencies and load-generation scenarios. ANN has been implemented on MATLAB.

This paper covers the modelling and the transient stability analysis of the IEEE 9 bus test system using ETAP. In this, for various faults on the test system fast fault clearing and load shed are analysed to bring back the system to the stability. Frequency is a reliable indicator if deficiency condition in the power system exists or not. Change in power demand or in production causes a fluctuation of the speed of the turbine-generator condition exists on the power system, resulting in fluctuation of the frequency of the power system. So rate of change of frequency is used as indicator of the transient stability of the system and to calculate the amount of load to be shed by adaptive load shedding and measures taken to maintain stability and frequency of the system.

The demand of MLI has increased recently as it is capable of generating quality waveform by using low voltage devices, reduced switching frequencies and reduced harmonics content of the output power. There are several topologies discussed and analyzed in literature in past decades. In this paper, we have considered three topologies: Diode clamped inverter (DC-MLI), flying capacitor (FC-MLI), cascaded H-Bridge inverter (CHB- MLI). We have taken CHB-MLI as a reference for explaining three techniques: phase disposition (PD), phase opposition disposition (POD), alternate phase opposition disposition (APOD). After analyzing these three techniques, we observed that PD is best technique as it gives less total harmonic distortion (THD) content in voltage level.

Underground coal mining has less production and high output cost (cost per unit of coal production) due to the low effective utilization of equipment and also depends on geological conditions of the mine i.e. mine environment and condition of the roof. As the electrical energy cost for the coal mining industry is increasing every year, coal mining enterprises must conserve electrical energy for the reduction in output cost. In this paper, energy-use analysis has been performed to concept a benchmark for coal production at minimum specific energy consumption in an Indian underground coal mine. In preliminary inspection, different energy data are collected for major high energy consuming areas in the mining plant. A power balance chart of different equipment used in the mine has been prep...

At any given moment, the electrical power produced by the generators must be equal to the electrical power consumed by the network to continue stable operation. Every change in this balance that disturbs the steady-state operation of the power system is referred to as a power imbalance. This power imbalance in the network leads frequency instability. To ensure system stability and availability during disturbances, generation trip, transmission and distribution equipment failure, generally utilize some type of load shedding scheme. Conventional non-adaptive load-shedding algorithm is not the most efficient scheme for all power system disturbances. Artificial Neural Network based load shedding method is employed to calculate the minimum amount of load to be shed due to the effect of the contingencies, to improve the transient stabilit...
