Review of Vector Control Strategies for Three Phase Induction Motor Drive

 

ABSTRACT:

Induction motor drives are at the heart of modern industrial and commercial applications. With conventional control techniques, induction motor drives have shown less than expected dynamic performance. With vector control techniques emerging as potential replacement in induction motor drives, this paper aims at highlighting various vector control strategies. Direct and indirect vector controls along with sensorless vector control are presented. Various speed control techniques are presented through the use of conventional controllers and Intelligent Controllers. A critical analysis and comparison is made with other control strategies.

 CONCLUSION:

 The use of vector control has been presented for Induction motor drives. A number of vector control schemes have been presented with merits and demerits of each. Different controllers (conventional and intelligent controllers) have been used in various schemes of vector control strategy. Potentially DTC is proving to be superior to other vector control techniques. Contrast to field oriented controller, it is more robust, does not require any transformation, current controller, or rotor position measurement. However, an improvement in torque ripples is the demand of this scheme. Sensorless vector control offers low cost and more reliability, but operation of this scheme in low speed region is one of its biggest drawbacks.

Phase Angle Calculation Dynamics of Type-4 Wind Turbines in rms Simulations during Severe Voltage Dips

ABSTRACT:

 To conduct power system simulations with high shares of wind energy, standard wind turbine models, which are aimed to be generic rms models for a wide range of wind turbine types, have been developed. As a common practice of rms simulations, the power electronic interface of wind turbines is assumed to be ideally synchronised, i.e. grid synchronisation (e.g. phase locked loop (PLL)) is not included in simplified wind turbine models. As will be shown in this study, this practice causes simulation convergence problems during severe voltage dips and when the loss of synchronism occurs. In order to provide the simulation convergence without adding complexity to the generic models, a first-order filtering approach is proposed as a phase angle calculation algorithm in the grid synchronisation of the rms type-4 wind turbine models. The proposed approach provides robustness for the simulation of large-scale power systems with high shares of wind energy.

CONCLUSION:

Owing to the large share of wind power in power systems of certain countries, especially in Europe, the need of power system analysis with WPPs arises. WT and WPP models have been developed by the academia and WT manufacturers, which are chosen as rms models in order to provide computational simplicity and speed, considering large-scale simulations. In addition, standards for the developed WT and WPP models have been developed by IEC and WECC working groups. As a common requirement of the grid codes, the developed models are utilised for short-term voltage stability and fault ride-through studies. The conventional method of instantaneous phase angle calculation, i.e. ideal grid synchronisation, performs well with moderately low voltage faults. However, it is shown that the physical fact of the LOS of WT converters during severe voltage dips is observed to cause simulation non-convergence problems with the instantaneous angle calculation method in rms simulations.

In this paper, a first-order LPF is proposed as angle calculation method in converter-based WTs in order to solve the nonconvergence errors during severe voltage faults. The proposed LPF method is shown in order to solve the non-convergence errors even for solid faults (i.e. a zero impedance three-phase fault). In addition, implementing a threshold triggering function to activate the LPF-based calculation only during severe voltage dips avoided any possible impairment during healthy steady-state operations. Moreover, the frequency deviation due to the LOS problem, which needs to be solved with additional control methods, is shown to be represented with the LPF method. Hence, the proposed LPF method gives the possibility to detect if the WPP experiences the LOS and hence to solve it.

The recently published IEC 61400-27-1 WTs electrical simulation models standard [1] has adopted the proposed idea of utilising a first-order LPF as phase angle calculation in rms simulations, which helps to obtain robust simulations, especially when a large-scale (e.g. Pan-European) power system with high share of wind power is simulated and analysed.

Sustainable power source is characterized as “vitality got from assets that are regenerative or for every single commonsense reason can not be drained.” Renewable vitality, additionally called elective vitality, is for the most part thought of as an option in contrast to customary vitality more often than not provided by the burning of petroleum derivative, for example, oil, coal or flammable gas. The prime wellspring of sustainable power source is sun based radiation, i.e. daylight. The Earth-Atmosphere framework gets around 5.4 x 1024 joules for each year in the sun based radiation cycle (Sorensen, 2004). The sun oriented irradiance at the highest point of the air is all things considered 1366 watts/meter-squared.

Vitality is famously hard to characterize. Usually characterized as the capacity to do work, yet this is an inadequate definition. American Supreme Court Justice Potter Stewart broadly said of erotic entertainment that he couldn’t characterize it, “however I know it when I see it.” Thus it is with vitality. It is anything but difficult to perceive in the majority of its few structures: mechanical (counting dynamic and gravitational potential), compound, atomic, electromagnetic (counting light and other non-atomic radiations), flexible, and warm. The SI unit of vitality is the joule, named out of appreciation for James Prescott Joule, who found the comparability of warmth and mechanical vitality. The joule is a determined unit, comparable to kg•m²/s² . It can likewise be communicated as newton-meters (Nm), however isn’t generally done to evade disarray with the units of Torque (N x m) The word vitality originates from the Greek words en and ergon which implies at work

What Are The Advantages Of Academic Projects? On the off chance that you come down to check the benefits of Academic Projects, there isn’t one however many. Scholarly Projects offers a splendid situation for the sole reason for examining specialized activities, look into works and applications which will be valuable for every last one. The examination works did at industry level are started at establish level, by understudies and their educating resources. Also, the ongoing activities created at school level by understudies are put to applications at industry level. Scholastic Projects therefore gives a stage to trade of information, thoughts and endeavors, from which the business and establishments could commonly profit. Moreover, Academic Projects additionally offers open doors for B.E. what’s  graduates, from everywhere throughout the nation, to come and turn into a piece of a few long haul extends that are done at grounds level crosswise over India. The vast majority of these activities are supported by the business and when totally built up, these ventures are grabbed by the business for ongoing application. Understudies and guides behind such fruitful tasks are perceived at the business level and turn into a piece of the ability based enlistment procedure of prestigious multinational organizations. In this way, however in a roundabout way, yet Academic Projects helps understudies construct an incredible vocation. It helps organizations to employ capable brains that can get their benefits multiplied in a brief length, by creating incredible constant applications. Foundations enrolled with Academic Projects can get to know the arrangement of other comparable establishments, parade their scholarly research works and secure a higher review for their school.

Who is Academic Projects for? Scholastic Projects is a consequence of the hard endeavors and imaginative brains of a gathering of Engineers. Created by engineers, this site is at first going to be a stage, exclusively of the designers and for the specialists. Understudies, foundations, tutors originating from building foundation and organizations managing designing items and administrations are most welcome . They all can discover space to interface and begin a gathering for dialog of specialized activities. However, this is only for the present. As and when we develop, this site will likely be extended to serve people and networks from fields other than building too.
