the aim of this study was the evaluation of acute genotoxic effect of effluent water of thermo-power plant by means of tradescantia root tips micronucleus test (mn), mitotic index and cell aberrations.   tradescantia , was experimentally treated (for 24 h), with effluent water of thermo-power plant in different dilution ratios (negative control – distilled water; primary untreated effluent wate...

The grid voltage modulated direct power control (GVM-DPC) is a novel regulation method for grid-connected source inverters (VSI). However, interactions between real and reactive powers still exist in GVM-DPC under unbalanced condition, which may deteriorate its transient performance. This article proposes decoupling GVM-DPC-based VSI systems based on the dynamic feedforward compensation strateg...

Active Power Filter (APF) can significantly compensate the current harmonics produced by nonlinear loads. To do this feature, harmonic detection reference generation play vital role. Direct Controller (DPC) has great harmony with instantaneous power compensation (PQ) algorithm as well ability to eliminate internal loops. In addition, DeadBeat (DBC) high compatibility for digital implementation,...

In this paper, a recurrent fuzzy-neural network (RFNN) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. Since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...

Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...

voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.

this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...
