This paper describes simple speed estimation technique for permanent magnet synchronous motors based on extended kalman filter. Speed estimation is required for Sensorless vector control of motor. A system is designed to estimate the rotor speed according to the mathematic model. Simulation is done by using MATLAB, results show that the EKF-based control system, which is able to implement the speed sensorless vector control for PMSM, can preferably track the rotor speed.

Power system state estimator uses the set of available measurements in order to estimate the state of the system. For the given measurements, the network observability analysis will determine if a unique estimate can be found for the system state. Network observability analysis can be performed using either numerical or topological approaches. In this paper optimal number and location of phasor measurement unit is performed using Differential Evolution algorithm. In addition single phasor measurement unit loss is also considered. To verify our proposed approach, simulations on 6-bus test system and IEEE 14-bus, 30-bus, 57-bus and 118-bus system are performed.

Advanced transportation technologies, such as hybrid-electric, battery-electric, and hybrid-fuel-cell vehicles, rely on high power dc/dc converters to interconnect and manage their power sources. This paper proposes a Novel Capacitor Switched Regenerative snubber circuit (NCRS) that greatly reduces the switching losses of the insulated-gate bipolar transistor (IGBT) in the boost converter used in Low Cost Hybrid Electric Auto Rickshaw (LCHA). The proposed circuit offers a unique Regenerative Operation thereby, a part of the switching voltage and current are utilized in charging of the snubber capacitor in once cycle and discharging of the same in the another cycle of triggering of the main switch, effectively passing on the energy stored in the capacitor to the output terminals. Due to the usage of high frequency, regenerative converters and switching devices the losses are reduced leading to a much more efficient performance of the engine. The DC/DC converter's efficiency and dynamic operational characteristics are henceforth the most important aspects of LCHA.

The object of this paper is to proposes a method for induction motors with adjustable-speed drive consisting of two five level diode-clamped converter connected back-to-back with transformer less configuration in medium voltage application. This paper delivers a remedy for the voltage stabilizing problem which occurs during the implementation of split dc capacitors. This problem has been reduced by using suitable switching technique in the proposed configuration. Multi carrier pulse width modulation technique has been dropped back behind the advanced Space vector PWM technique. The voltage and current harmonic values of the induction motor output were reduced by using the space vector PWM switching technique.

Use of Flexible AC Transmission Systems (FACTS) for voltage stability improvement in power system has been well established. Optimization of various parameters so as to obtain improved voltage profile, minimal total system loss, minimal reactive power transfer and maximization of the stability limit have been achieved using various techniques. The present paper employs the Particle Swarm Optimization (PSO) to achieve optimized parameters as stated above by optimal sizing and allocating of a multiple Static synchronous Compensator (STATCOM) in a power system. The effectiveness of the proposed work is tested for IEEE-30 bus test system with multiple STATCOM devices. This paper provides the details of the results obtained using PSO on the IEEE-30 bus test system, using multiple STATCOM for voltage stability improvement under various load conditions.

It is essential to monitor the condition of Aluminum Conductor Steel Reinforced (ACSR) overhead power cables for efficient power transmission applications. Inspect the thermal ratings of power cable as a function of environmental effects, which are the affecting factors for the condition of the cable. Simulated environmental effects were introduced in the ACSR cable and the current induced temperature is observed. This paper introduces an approach for a condition monitoring of overhead power lines. The thermal model of overhead line and its function is simulated by resolving the thermal balance equations with MATLAB Simulink. In the simulated behaviour of the conductor and its surface characteristics, temperature and emissivity affects the conditions of the Powerline. The results are given that condition monitoring is a promising technique for ACSR cables to ensure the safety and quality operation.
