چکیده
Abstrac tThis paper deals with a novel single-point strategy for the detection of harmonic sources in power systems. It is an enhancement of a previous strategy, developed by authors, which is based on the IEEE Std. 1459-2000 approach. In the paper, the effectiveness of the strategy is investigated, by means of simulation tests, which were carried out on a IEEE standard three-phase test power system. The analysis is carried out by considering also the presence of the measurement transducers.

This paper deals with a novel single-point strategy for the detection of prevailing harmonic sources downstream or upstream the metering section in three-phase power systems. It is an enhancement of a previous strategy, already developed by the authors and it is based on the comparison of three non-active power quantities which are based on the IEEE Std. 1459-2000 approach. The method does not ...
متن کاملEconomic Load Dispatch using PSO Algorithm Based on Adaptive Learning Strategy Considering Valve point Effect
Abstract: In recent years due to problems such as population growth and as a result increase in demand for electrical energy, power systems have been faced with new challenges that not existed in the past. One of the most important issues in modern power systems is economic load dispatch, which is a complex optimization problem with a large number of variables and constraints. Due to the comple...
متن کاملA graph search algorithm: Optimal placement of passive harmonic filters in a power system
The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. The objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...
متن کاملDetection of Disturbing Loads in Power Systems using Non-Active Power
This paper detects the disturbing loads in distorted and/or unbalanced three phase three wire power system. It is based on the simultaneous measurement of four non-active power quantities, which are found on the IEEE Std.1459-2000 method. It allows, achieving better knowledge of the power system when both harmonic distortion and un-balance are present. The proposed method requires only the fund...
متن کاملInvestigation of Power Factor Behavior in AC Railway System Based on Special Traction Transformers
The single-phase traction load has essentially an unbalance characteristic at the Point of Common Coupling (PCC), which injects harmonic into the utility grid. In this paper, the effect of harmonic distortion and unbalance loading are investigated simultaneously for electrical railway systems. Special traction transformers (i.e. single-phase, V/V, Wye-Delta, Scott, and Le Blanc) are used betwee...
