This young ES has some limits and drawbacks which should be more nurtured to make it more mature. One of these weaknesses is no protection on the non-critical load which is series with the ES. It is true that ES has to keep the voltage of critical loads in the nominal value, but it is also true that the voltage of non-critical load still has some limitations which should be taken into consideration. This paper proposes new control strategies to protect the non-critical load against large voltage fluctuation without losing effectiveness of ES. In order to prove validity of this scheme a typical power grid is adopted for simulations via MTLAB/SIMULINK software.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130431608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a novel method is introduced to determine the switching instants of the thyristors which is done through the stator flux estimation. Compared to other frequent switching schemes, the proposed method is simple, less parameter sensitive and free from some additional circuits or transducers. Also, a comprehensive flux observer is presented to estimate the stator fluxes. Some disadvantages concerning the other flux observers such as initial conditions and dc drift problem, large time constant at high speeds and phase and magnitude error in low speeds are eliminated by the proposed observer. Simulation results show the validity of the proposed switching scheme and flux observer in a wide speed range.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123739205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A power electronic interface is needed in order to connect a Wind Energy Conversion System (WECS) to the load or the utility grid. Control of this interface, which consists of generator- and grid-side converters, is a very important and demanding task. The main purpose of controlling the generator-side converter is implementing Maximum Power Point Tracking (MPPT). In this paper, the conventional Hill Climbing Search (HCS) MPPT algorithm is modified using fuzzy logic theory in a way that its performance has been enhanced in terms of accuracy and speed. This modified algorithm enables the system to continuously extract the maximum energy from the wind by generating an appropriate rotor speed reference. Vienna rectifier is used as the generator-side converter due to its noticeable advantages in WECSs. A non-linear control scheme based on Sliding Mode Control (SMC) is utilized in this work for efficient speed control, which has notable advantages over linear controllers. Simulation results verify the satisfactory performance of the control scheme and the modified MPPT algorithm. A comparison is also made between SMC and PI controllers regarding their speed control performance.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128689566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimization of induction motor parameters using a design inverter seems to be ideal. However, as inverter modulation system is of digital type, machine voltage and current involve many harmonics components. High number of harmonics in voltage and current leads to inability to use an analytical method for harmonics and THD studies unless only a small number of harmonics are considered, resulting in reduced accuracy. In this paper, optimization of stator linkage flux's harmonics effective function is proposed. Due to several advantages including limited number of elements and utilization of SVPWM modulation parameters (modulation index and magnitude of reference voltage vector), this function is used for harmonic analysis of induction motors' drive in space vector modulation (SVM). This function is obtained by accurate vector operations without any approximation, thus it has an acceptable accuracy verified by simulation results.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121755915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the voltage stress of the main switch is low which causes a low on-resistance (RDS-on) switch to be used which reduces conduction loss and increases the efficiency.

The accurate estimated flux grantees the desirable sensorless drive function. There are different methods for flux estimation that the voltage model is simplest ones. These methods are sensitive to the stator resistance; therefore have poor performance and incorrect estimated flux at very low speed. In this paper a novel flux estimation method is proposed based on model reference adaptive system (MRAS). In the proposed MRAS method the equations of the reference and adaptive models are based on stator current. Traditionally, MRAS observer is used for estimation different parameters such as rotor speed and resistances. Now in novel technique the stator flux is directly estimated from a MRAS observer. The proposed method is less sensitive to the stator resistance so has proper performance at the low speed operation. The robustness and the dynamic performance of the proposed observer are evaluated by simulations.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129402770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing conventional control strategies of permanent magnet synchronous motors (PMSMs) and brushless DC motors (BLDCMs) leads to lower efficiency and causes unwanted torque ripple, vibration and acoustic noises. This paper explores a review on control of non-ideal PMBL motors and investigates the torque response of non-ideal PMBL motor while is controlled with conventional control strategies and presents a novel torque ripple minimization method. Investigated control strategies include quasi-square current control using dc-link current, quasi-square current control using three phases current, direct torque control, vector control, and pseudo vector control that are used for speed control of non-ideal PMBL motor. Then, a novel torque ripple minimization based on selective torque harmonic elimination and using one cycle control strategy is suggested. Simulation results indicate the non-ideal PMBL motor by novel proposed method develops smoother torque and lower torque ripple rather than all previous control strategies. It is suitable for any PMBL motor with any back-EMF voltage waveform.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"541 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125522982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In ideal BLDC with trapezoidal back-EMF torque ripple elimination can be achieved using rectangular stator current, while in motors with non-ideal back-EMF, feeding the rectangular current leads to more torque ripple. In this paper at first, a mathematical expression for torque ripple harmonics is done. Then for a non-ideal BLDC motor with known harmonic contents of back-EMF, calculation of desired reference current amplitudes, which are required to eliminate some selected harmonics of torque ripple, is reviewed. In order to inject the reference currents to the motor windings, an adaptive input-output feedback linearization control is proposed, which generates the reference voltages for three phases Voltage Source Inverter (VSI). Also, this method is robust against the motor parameter variations like as stator's resistance and leakage inductance.
