The prediction of temperature distribution in ester oil (natural and synthetic ester oil) filled transformer due to different types of cooling modes are important for thermal designer in order to utilize the ester oil benefits of biodegradable, fire safety substations and continuous overloading capabilities with respect to mineral oil. It is still a technical challenge for ester oil to utilize in transformers since higher viscosity of ester oil will leads to reduce the heat transfer process mainly in convection. With the ester oil in a transformer, there will be reduction of convection fluid currents which leads to higher temperature in top temperature oil and winding temperature rise in ester oil filled transformers. In this paper, the effects of mineral oil and ester oil on top oil rise, winding rise and hot-spot temperature arising from their potentially different thermal properties are investigated using Thermal hydraulic network model (THNM) on 60/75/90MVA, 220/33kV transformer. The power losses are calculated from FEM based simulations and experimental data for thermal analysis using THNM model. The direct impact of oil flow rate and total pressure drop over the windings in oil directed (OD) cooling modes are analyzed under rated loading and 120% continuous overloading capabilities (108MVA) with respect to mineral oil.

Mineral oil is the most commonly used insulating oil in distribution and transmission transformers. It possesses good physical, chemical and insulating properties making it one of the most suitable oils for insulation purpose. However, a few of its properties like low fire point pose serious threats to the electrical power system. Moreover, its nature of nonbiodegradability makes its usage a serious concern and motivates engineers to think about other alternatives to be used as dielectric oils in transformers. Vegetable oils like palm oil, rapeseed oil etc. are being used for the insulation purposes in transformers for over last two decades. In this paper, important parameters such as breakdown voltage, relative permittivity, capacitance and dissipation factor (tan δ) have been studied for different insulator oil samples. The samples are considered as Palm Oil (P.O.), Coconut Oil (C.O.), Rapeseed Oil (R.O.), Sunflower Oil (S.O.), and mineral oil (M.O.). In addition, a fuzzy logic-based approach with total of 729 rules has been developed for the selection of insulating oil based on the given set of oil properties. The results show the validation of the fuzzy logic- based model in selecting the type of oil while comparing it with the experimental results.

The renewable energy intermittency indicating generation unavailability and volatility in a microgrid need to be addressed with prime attention. Here, in this work, the operational reliability and generation adequacy are reinforced by integrating a battery as the energy storage to the variable speed wind power generation system (WPGS). The grid interconnection to the system and combined performance offer significant benefits of improved power quality (PQ), energy sufficiency and surety by managing the local load support. The control of the battery allows the generation of the grid reference current. The grid side power converter utilizes the maximum-likelihood estimator based adaptive filter for improving the PQ indices by addressing the prevailing concerns stemmed by nonlinear loads. The control has high tracking performance while dealing with the contingency event of load variation. The machine side power converter utilizes vector control for obtaining the switching pulses. A hardware prototype is developed and the test results acquired substantiate that the work carried out is effective, reliable and offer improved PQ indices.

In this paper, a modified generalized integrator (GI) control technique with a reduced number of integrators, is presented for the control of grid interfaced single stage solar PV array integrating with unified power quality conditioner (SPVA-UPQC) system. This controller has a reduced number of integrators to estimate the fundamental active components of the distorted signals enabling DC offset elimination. Further, these fundamental signals are used to generate the reference signals for shunt compensator. The SPVA-UPQC helps to mitigate both current and voltage related power quality (PQ) problems such as it eliminates harmonics, load unbalancing, reactive power compensation, voltage sag-swell elimination, as well as it provides clean energy generation, by interfacing solar PV array at the common DC link of UPQC. In order to evaluate the performance of this system with presence of nonlinear load, simulation results are presented in environment of MATLAB/Simulink. The experimental performance of the SPVA-UPQC system is validated through developed prototype and the corresponding results are presented herein for various conditions like grid voltage sag, grid voltage swell, load unbalancing, solar irradiation variation and harmonics. The total harmonic distortion (THD) of the grid voltages and currents are attained within the limits as per the IEEE-519 and IEEE-1159 standards.

In this paper, a framework for joint planning of photovoltaic (PV) based renewable distributed generation and battery storage system (BSS) for a distribution system including demand response (DR) is developed. The planning problem is formulated as a mixed integer second order conic programming to simultaneously minimize energy losses and maximize photovoltaic capacity that can be integrated in the distribution system. Simulations are conducted on 33-bus system to demonstrate the effectiveness and feasibility of proposed approach. The simulation results show that optimal allocation of PV and BSS in presence of DR leads to significant increment in energy saving and power that is injected by PV in distribution system.

This paper deals with the control algorithm based upon an enhancement in notch filter (NF) applied to a grid connected single stage solar photovoltaic (PV) system during odd circumstances such as grid voltage distortions, PV insolation variation and fluctuation in the grid voltage etc. The enhanced-notch-filter (ENF) control extracts the positive sequence components from the grid voltages during voltage distortions and direct current (DC) offset. In single stage PV array system, during transients in the system, a Proportional-Integral (PI) controller with fixed gain doesn't give the suitable response. Therefore, a fuzzy based tuning of PI controller gains is implemented in order to overpower the shortcomings of the fixed gain PI controller. The voltage source converter provides the PV power to the grid. Tests are performed at different dynamic situations on a prototype for the validation of the system performance.

This paper presents a rotor position estimation scheme for high performance Permanent Magnet Synchronous Motor (PMSM) drive. The rotor position of PMSM drive is estimated by measuring stator voltage and current quantity of PMSM drive. Initially the PMSM drive run by V/F control technique. Once the motor reaches up-to 10% of synchronous speed, then V/F control technique switch over to sensorless control algorithm. Sinusoidal Pulse Width Modulation (SPWM) technique has been used to generate three phase voltages from the dc link source. The closed-loop speed control has been shown to be effective from standstill to rated speed. Computer simulation and experimental results are presented to demonstrate the effectiveness of the scheme.

Synchronous reluctance motors (SynRM) are increasingly being considered for various application due to their rugged structure and maintenance-free operation. Considering that remote locations in India are fed by a weak power grid, it is necessary to know the consequences faced by an SynRM coupled to a constant torque load, if a sustained voltage dip (beyond the tolerable limits of the motor)occurs at the terminals of the motor. This work presents a novel analysis of the behavior of the motor when a sustained voltage dip, beyond the tolerable voltage dip margin, occurs at the motor terminals. The changes in speed, torque, current and other operating quantities after a large voltage dip occurrence, are also investigated thoroughly. This analysis is supported by simulations in MATLAB/Simulink as well as experimental results. This paper paves the way for engineers working on drives to understand and tackle the problem related to sustained voltage dips at the motor terminals, while it is driving a constant torque load.
