Nimpitiwan, N.; Chaiyabut, C. Intelligent Systems Applications to Power Systems, 2007. ISAP 2007. International Conference on, 2007
This paper proposes a genetic algorithm (GA) based centralized voltage and reactive power control strategy. The proposed strategy aims to prevent voltage fluctuations and/or unconvergence cases by coordinating the operation of voltage/ reactive power control equipments, such as on load tap changer (OLTC) of transformers, automatic voltage regulator (AVR) of distributed generations, and shunt capacitors (SCs). The problem is formulated ...
Grant, L.; Venayagamoorthy, G.K.; Krost, G.; Bakare, G.A. Swarm Intelligence Symposium, 2008. SIS 2008. IEEE, 2008
This paper presents a comparison of swarm intelligence and evolutionary techniques based approaches for minimization of system losses and improvement of voltage profiles in a power network. Efficient distribution of reactive power in an electric network can be achieved by adjusting the excitation on generators, the on-load tap changer positions of transformers, and proper switching of discrete portions of inductors ...
Simas, E.F.; de Almeida, L.A.L.; de Lima, A.C. Instrumentation and Measurement Technology Conference, 2005. IMTC 2005. Proceedings of the IEEE, 2005
On load tap changers (OLTC) are widely used for voltage regulation in electricity networks. Noninvasive vibration methods for condition monitoring of internal electrical contacts have been recently proposed in the literature. The vibration signals emitted during the tap changes are usually recorded and post-processed using spectral analysis and some pattern classifier technique. To reduce the complexity of the classifier, a ...

The latest distribution management systems tend to incorporate optimization functions for the short-term scheduling of the various energy and control resources available in the network (e.g., embedded generators, reactive power compensators and transformers equipped with on-load tap changers). The short- term scheduling procedure adopted in the paper is composed by two stages: a day-ahead scheduler for the optimization of distributed ...
Meyer, A.S.; Van Coller, J. Africon, 1999 IEEE, 1999
The use of cost-effective ultra-light medium voltage power lines for remote rural communities is proposed. This will require the development of an electronic on-load tap changer to cope with the excessive voltage drops. The tap changer will be used with typical rural distribution transformers and a novel feature will be that it will contain intelligence so that the tap position ...
