Y-capacitor
Opis:: Putting a Y-capacitor between the primary ground and secondary ground is a common practice in industry to reduce EMI; but, this capacitor increases touch current. A method is discussed to measure the touch current at circuit design level. An optimum value of Y-capacitor is predicted without exceeding touch current limit. Experimental results of touch current measurements and EMI measurements are analyzed.

Opis:: This paper presents the optimization of large-scale practical distorted distribution network for maximum losses reduction and voltage profile improvement based on two-stage methodology for capacitor placement problem. In the first stage, a fuzzy expert system (FES) is used to find the optimal capacitor locations, and in the second stage, a selective particle swarm optimization (SPSO) is used to find the optimal capacitor sizing. The problem is posed as an optimization problem with objective to minimize the total cost of power and energy losses and capacitor banks including constraints for bus voltage and total harmonic distortion (THD) limits. Simulation results show the benefits from optimization and the effect of harmonics on optimal capacitor placement.

Tematy:: radial feeders

load characteristics
Opis:: The paper gives the results of applying an alternative procedure for the economical as-sessment and optimization of the shunt compensation of radial power distribution feeders with con¬centrated and/or distributed loading, taking into account the feeder copper losses as well .is the installation cost of capacitors. In addition to the energy and capacitor specific costs, the objective function depends on the si/e and location of the capacitor, the feeder resistance, the voltage level, and the load current. The results <»f a detailed parameter study on the impact of the load parameters are presented. The study focuses primarily on the impact of the load factor, the load power factor as well as the feeder's loading profile.
