Abstract

The load frequency control problem is non interactive mainly due to small load variations in power system. Maintaining power system frequency at constant value is very important for the health of the power generating equipment and the utilization equipment at the customer end. The job of automatic frequency regulation is achieved by governing systems of individual turbine-generators and Automatic Generation Control or Load frequency control system of the power system. The main objective of this paper is to present a critical literature review and aimed to highlight the various control and structural aspects of Automatic Generation Control used in multi area interconnected power system. Also this paper work reported in the Automatic Generation Control schemes based on power system models and control strategies are reviewed.

Abstract

Transformer failures in a power system very often lead to forced outages, blackouts and revenue losses. The power system can be run smoothly if the remnant life of the transformers is predicted accurately before such devices fail to perform. The remnant life estimation gives a flexible decision on replacement or relocation of power transformers. These devices are the connecting links between transmission and distribution end. The lifetime of the power transformer is mainly associated to the insulation system condition. In the present work experimental data obtained by conducting dissolve gas analysis, moisture content, breakdown voltage, interfacial tension, furan compounds and dielectric dissipation factor or tan delta on the various power transformers of Himachal State Electricity Board has been utilized to develop the proposed remnant life estimation model. The proposed Fuzzy logic model utilizes the MATLAB graphical user interface tool to interpret the life expectancy of the power transformers very accurately.

Abstract

This paper Introduces, a new concept of controlling complex power (simultaneous active and reactive powers) through series inverter of UPQC is introduced and named as UPQC-S. The proposed concept of the UPQC-S approach is mathematically formulated and analyzed for voltage sag and swell conditions. The developed comprehensive equations for UPQC-S can be utilized to estimate the required series injection voltage and the shunt compensating current profiles (magnitude and phase angle), and the overall VA loading both under voltage sag and swell conditions.The simulation studies demonstrate the effectiveness of the proposed concept of simultaneous voltage sag/swell and load reactive power sharing feature of series part of UPQC-S. The significant advantages of UPQC-S over general UPQC applications are:1) the multifunction ability of series inverter to compensate voltage variation (sag, swell, etc.) while supporting load reactive power; 2) better utilization of series inverter rating of UPQC; and 3) reduction in the shunt inverter rating due to the reactive power sharing by both the inverters.The UPQC apparatus is a good compensation system if wide installation of shunt units is needed. An increase in the percentage of the protected load enhances the voltage stabilization interval over which the UPQC can significantly improve the power quality.

Abstract

This paper proposes an optimal design method for an hybrid active power filters (HAPFs) set at high voltage levels to satisfy the requirements of Harmonic filtering, Power factor correction and reactive power compensation for Different Loads to Enhance Power Quality Using PSO [16]-[19]. Multi objective Optimization models for HAPF were constructed. Detuning effects and faults were also considered by constructing Constraints during the optimal process, which improved the reliability and practicability of the designed filters. Furthermore, the Particle swarm optimization algorithm was developed for searching an optimal solution of planning of filters.
