measurement of magnitude and frequency of the voltage flicker is very important for monitoring andcontrolling voltage flicker efficiently to improve the network power quality. this paper presents twonew methods for measurement of flicker signal parameters using shuffled frog leaping algorithm(sfla) and imperialist competitive algorithm (ica). this paper estimates fundamental voltage andflicker ...

In Electrical Impedance Tomography (EIT) measurement sinusoidal currents are applied on a surface of the human body and voltage response is measured in order to reconstruct conductivity distribution in a body cross-section. We have constructed an experimental system for EIT measurement based on voltage response to short current pulses. In this case resistive components of body impedance are mea...

Voltage control is one of the imperative issues in the smart distribution control system. While traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. With using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

With the expansion of introduction of renewable energy sources (RES) such as photovoltaics (PV), voltage fluctuations (fluctuated voltage by PV output ups and downs depending on sunshine changing) in distribution network can be increasing. As a method of suppressing voltage fluctuations, intensive control of voltage control equipment by the introduction of a centralized voltage control system (...

A voltage transformer, as voltage signal detection equipment, plays an important role in a power system. Presently, more and more electric power systems are adopting potential transformer and capacitance voltage transformers. Transformers are often large in volume and heavyweight, their insulation design is difficult, and an iron core or multi-grade capacitance voltage division structure is gen...
