The article discusses application of AC/DC/AC converter cooperating with an induction generator in small hydroelectric power plants. The induction generator works with power grid or a separated group of receivers, enabling to generate power even at low speeds of the turbine. The article provides also results of the investigation concerning the functioning of the generator coupled with AC/DC/AC ...

Abstract: A permanent magnet (PM) synchronous generator system driven by wind turbine (WT), connected with smart grid via AC-DC converter and DC-AC converter, are controlled by the novel recurrent Chebyshev neural network (NN) and amended particle swarm optimization (PSO) to regulate output power and output voltage in two power converters in this study. Because a PM synchronous generator system...

Abstract This article is focused on the simulation and implementation of simple fuzzy logic excitation control of a synchronous generator. In MATLAB/SIMULINK is simulated model of the synchronous generator connected to an AC system. A simple fuzzy logic control scheme is simulated for voltage control and generator stabilization. This simulation is compared with the behaviour of the real laborat...

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Labeling of specific antibodies with bifunctional chelated Actinium-225 (Ac; an generator) allows the formation of new, highly potent and selective -emitting anticancer drugs. We synthesized and evaluated a radioimmunoconjugate based on 3F8, an IgG3 antibody that specifically binds to ganglioside GD2, which is overexpressed by many neuroectodermal tumors including neuroblastoma. The Ac-1,4,7,10...

Model complexity may have a significant impact on transient stability results of mixed AC/DC systems. The dynamics of various mixed AC/DC models with a focus on different generator orders and multi-level modular converter (MMC) VSCHVDC model types is investigated within this paper. MMC VSC-HVDC converter models are based on average value model (AVM) and simplified AVM, while 2 nd , 3 rd and 6 t...

This paper presents Maximum Power Point Tracking (MPPT) controller design of Doubly Fed Induction Generator (DFIG) using Genetic Algorithm (GA). Essential feature of proposed controller is that it is used to trace the maximum power when wind speed is lower than the rated wind speed. Doubly-Fed Induction Generator DFIG has stator terminals are connected directly to the grid. However, the rotor t...

Targeted radiotherapies maximize cytotoxicty to cancer cells. In vivo α-generator targeted radiotherapies can deliver multiple α particles to a receptor site dramatically amplifying the radiation dose delivered to the target. The major challenge with α-generator radiotherapies is that traditional chelating moieties are unable to sequester the radioactive daughters in the bioconjugate which is c...

This paper discusses the development of new control method using artificial neural network model for the optimum operation of hybrid renewable energy system (HRES) connected to AC grid. The hybrid system consists of wind generator (WG), diesel generator (DG), and flywheel energy storage system (FESS). The system is based on permanent magnet synchronous machines (PMSM) which are controlled by sl...
