Methods for Reduction of Voltage Unbalance in Weak Grids Connected to Wind Plants



1 INTRODUCTION
The location of wind turbines is based on wind properties. Normally, areas with good wind resources are geographical remote. The cost of the electrical power grid connecting the wind plants should be as low as possible. The voltage quality in a weak power grid may be poor, and unbalanced voltages can occur. Induction machines are attractive as wind turbine generators due to their low ....etc

ABSTRACT
In this paper, the convergence ability of Distribution Systems Power Flow Algorithms, which are widely used for distribution systems analysis, is compared with different voltage-dependent load models. The convergence ability of methods are also evaluated for different tolerance values, voltage levels, loading conditions and R/X ratios, under the wide range exponents of loads. Results show that Ratio-Flow method is preferable from other methods.

single phase ac voltage regulators using triac and diac combination for r load and rl load

Abstract

The DIode AC switch, or Diac for short, is another solid state, three-layer, two-junction semiconductor device but unlike the transistor the Diac has no base connection making it a two terminal device, labelled A1 and A2. Diac s have no control or amplification but act much like a bidirectional switching diode as they can conduct current from either polarity of a suitable AC voltage supply.In our tutorial about SCR s and Triacs, we saw that i ....etc

Introduction
The zero-cross family of optically isolated triac drivers is an inexpensive, simple and effective solution for interface applications between low current dc control circuits such as logic gates and microprocessors and ac power loads (120, 240 or 380 volt, single or 3-phase). These devices provide sufficient gate trigger current for high current, high voltage thyristors, while providing a guaranteed 7.5 kV dielectric withstand voltage between the line and the control circultry. An integrated, ze ....etc
