The five-phase induction motor inherently has the minimal torque ripple. However, when it is controlled by direct torque control (DTC) technique, the torque ripple increases due to the presence of a hysteresis torque comparator. The classical five-level torque comparator is presented in the previous literatures to control the torque ripple. However, this comparator has the drawback of wrong selection...
This paper presents an integrated high power battery charging topology by incorporating a split three phase induction motor for electric vehicle. In charging/vehicle to grid mode, stator winding is used as an inductive filter between grid and converter. During this operation, the rotor of machine is kept in stationary position as rotating magnetic field is cancelled out due to built-in nature of split...
Model predictive torque control (PTC) is simple and effective control method for induction motor drives. The conventional PTC uses all seven vectors, six active and one zero vector, to calculate cost function and improve torque dynamics. But this increases the computational burden on the microprocessor. Also use of zero voltage vector (VV) causes increase in common mode voltage (CMV). In this paper...
The analytical assessment of 5.05 kWp grid tied photovoltaic plant performance on the system level has been carried out in this study. The solar PV plant has been installed on the roof of the block-A of the Darshan Institute of Engineering and Technology, Rajkot. India. The Darshan Institute of Engineering and Technology has been monitoring and recording all the parameters of 5.05 kWp grid tied solar...
The aim of paper is to employ digital fractional order proportional integral derivative (FO-PID) controller for speed control of buck converter fed DC motor. Optimal pole-zero approximation method in discrete form is proposed for realization of digital fractional order controller. The stand-alone controller is implemented on embedded platform using digital signal processor TMS320F28027. The five tuning...
The hour ahead load forecasting is used for the reliable and proactive operation of the power system. The hour ahead load forecasting is a one type of Short Term Load Forecasting (STLF). The mostly STLF is used for the spinning reserve capacity, unit commitment and maintenance planning in the power system. In this paper the Linear Regression (LR) and the Artificial Neural Network (ANN) are used to...
The distribution feeders often get overloaded under peak power demands. This situation is generally countered by load shedding, which leads to financial losses to utilities and individual users. The compensation of real/reactive power not only provides the voltage profile improvement but also ensures the sustain power to the consumers. This paper presents the new control algorithm to support the real...
This paper presents a new Maximum Power Point Tracking (MPPT) algorithm based on golden section search technique for tracking maximum power point in photovoltaic (PV) systems. This method is robust and also has a fast response as compared to the conventional MPPT algorithms. This algorithm has guaranteed convergence under continuous variable atmospheric conditions. The search variable voltage is used...
The PV system design and its performance evaluation test before installation could be more costly and time consuming. This could be performed with accuracy in the laboratory without having PV array by using the emulator. This paper presents the PV emulator using real-time algorithm execution of the PV array mathematical model and generating the scaled output power from the AC-DC power supply. The...
In this article, an improved integrated battery energy storage system (BESS) controller for distributed energy system is presented. The BESS is integrated in parallel with the full wave bridge converter into the distributed energy system network. In a normal operating mode, the BESS serves as a power conditioner as well as an active power filter in a distributed power system network. This work presents...
