In this paper, the performance of a doubly-fed induction generator subjected to unbalanced grid voltage is presented. Instead of using double vector control and decomposing all the unbalanced vectors to positive, negative and zero sequence components the present scheme involves PI controller based stator flux oriented vector control. The power reference generation is based on the measured active power and estimated torque in order to reduce the torque and active power oscillations using Rotor Side Converter (RSC). The Grid Side Converter (GSC) is used to reduce the dc voltage oscillations and to maintain sinusoidal current exchange with the grid. Numerical simulations are carried out in PSCAD/EMTDC for the laboratory 3-hp DFIG test set up.

Voltage instability is a major problem that is attracting worldwide interest because of its consequence of voltage collapses. These days' Kerala power system operate closer to their stability limits because of the economic considerations, making large amount of power transfer from long distance and an inadequate supply of reactive power which contribute to system voltage instability that eventually leads to voltage collapse. So the stability margin has to be estimated and to know the loadability of the power system is essential in the real time system for voltage stability assessment. This paper investigates the enhancement of voltage stability using Static Compensator (STATCOM) in a wind integrated Central Travancore wind integrated power system. Wind energy is gaining attention among a variety of renewable energy resources mainly because it is a clean source of energy, renewable and also its running cost and maintenance cost is very less compared to other energy sources. Wind generation requires some device to smoothen the output from a wind turbine and a STATCOM connected to the bus performs this operation along with the property of voltage stability enhancement. The studies made in this paper are done with power system analysis toolbox (PSAT), a powerful toolbox in MATLAB for power system analysis.

STATic synchronous COMpensator (STATCOM) which is used for reactive power control, has the capability for voltage regulation of grid voltage at the point of common coupling (PCC). This is achieved either by injection or absorption of certain amount of reactive power. This control method is efficiently faster in tackling the voltage fluctuating problems[1]. Based on inverter configuration there are two types of STATCOM: Voltage source inverter (VSI) - based and current source inverter (CSI)-based STATCOM[2]. The closed loop feedback controller can be designed to meet different objectives. Conventional Proportional Integral (PI) controllers produce satisfactory response, provided the parameters kp and ki are well tuned. State feedback controller using the d-q reference frame can be designed to give a satisfactory dynamic response. In this paper, state feedback control method is proposed for VSI based STATCOM. Simulation results using MATLAB/Simulink indicate superior dynamic response with the proposed controller.

Transmission line is a vital component that acts as a bridge between the generating stations and end users. In the power system, reliability and stability must be ensured to provide continuity of service. Transmission lines run over several kilometers will have the chance for occurrence of fault. In order to maintain stability, faults should be cleared at short span of time with recent advancements in signal processing. In this paper, a novel technique for the protection of transmission lines is proposed. The proposed system uses Discrete Wavelet Transform (DWT) which is widely used in recent times for power system protection. DWT is used here to extract the hidden factors from the fault signals by performing decomposition at different levels. Daubechies wavelet “dB6” is used with single level decomposition and adaptive threshold is calculated to discriminate and detect the faulty phase. The location of faults is carried out by obtaining the local fault information and remote location fault information along with the transmission line length. The system is independent of any statistical system data and has negligible fault resistance. Test system is modeled and fault signals are generated to test the reliability of the algorithm. The proposed system promises the result by detecting, classifying and locating all the ten faults possible in the transmission line of the power system.

This paper describes an intelligent measurement system for Power Quality (PQ) assessment. Computational guts are based in Higher Order Statistics (HOS) and the intelligent decision system is based in the Case-Base Reasoning (CBR) paradigm, which could re-configure its parameter according to the power net conditions. The power signal characterization is done using a sliding window procedure, and calculating the variance, the skewness and the kurtosis over the points inside the window. Those values are introduced in the CBR system and the signal state is returned. If the signal is healthy, the system study the current HOS values for substitute the normal considerations of the CBR system. This procedure returns a precision over the 90%.

Presently most of the countries are looking towards the renewable energy systems like solar PV systems to overcome the drawbacks of conventional energy systems. This paper mainly deals with the power conditioning system controlled with FPGA for solar PV fed systems. A power conditioning system is proposed here for PV System comprising of 2 stage power conversion using FPGA. The first stage converts the variable DC voltage obtained from solar PV module/array into fixed DC using Boost converter which operates in voltage mode control technique. In the second stage of power conversion, the output of the first stage is fed to 3-phase, 3-level Diode clamped Inverter and the same is controlled by level shifted Sinusoidal pulse width modulation technique to convert fixed DC into 3 phase AC to drive 3 phase AC loads effectively.

This paper discusses the proportional-integral-derivative control scheme for a twin rotor multiple input multiple output system (TRMS), which is a nonlinear system with two degrees of freedom and cross couplings. The objectives of the work are to stabilize the TRMS, to attain a particular position and to make it to track a trajectory. Four PID controllers are used for achieving the objectives. The parameters of the PID controllers are tuned using the real valued genetic algorithm (RGA). The initial search range of the RGA is obtained using a control design optimization (CDO) technique. The control scheme is initially implemented for the decoupled system viz., horizontal and vertical 1-degree of freedom (1-DOF) systems, using 1 PID controller for each system, and it is followed by the implementation of the control scheme for the 2-degree of freedom (2-DOF) System.

This paper deals with the design and simulation of integrated controller for T-source inverter (TSI) based photovoltaic (PV) power conversion system. Photovoltaic (PV) module can generate direct current electricity without environmental impact and contamination when is exposed to solar radiation. Due to non linear characteristics of PV modules, which results in unique maximum power-voltage curve, it depends on the irradiation and temperature. So it needs to track the maximum power with help of maximum power point tracking (MPPT) controller. Here the Incremental conductance (INC) algorithm is used to reduce the oscillations in steady state, improve the tracking accuracy, fast response speed. The DC link controller is used to sense the dc link voltage value and compares it with the reference value of capacitor voltage and changes the reference current correspondingly. Here DC link controller and MPPT controller are unified and produce a shoot through ratio and improve the response time of MPPT controller. Due to integrated controller the settling time is reduced. The pulses are generated for the switches of the T-source inverter. T-source inverter has advantages over Z-source inverter fewer reactive components, high voltage gain and reduces the voltage stress across the switches. The modified space vector pulse width modulation is used to reduce the harmonic distortion and to prevent unnecessary switching in the device. Integrated controller for T-source inverter based photovoltaic power conversion system is simulated using MATLAB/Simulink.
