This paper presents a simulation model of electrical components of a grid connected 50 kW single shaft micro-turbine in MATLAB-simulink GUI environment. Micro-turbine consists of a PWM inverter to control the injected power to the load. Deploying micro-turbines with Combined Heat Power (CHP) capability make it so interesting to use in distributed generation. Employing DG creates an un-sinusoidal voltage...
A Multilevel shunt active filter is proposed to reduce the harmonic contents in source currents of a harmonic polluted three phase system supplying a non-linear load. The shunt active filter is designed with a seven level cascaded H-bridge inverter. To generate the required compensation currents Multicarrier PWM Current control method is used. The reference compensating currents are extracted from...
In this paper, a Z-source hybrid active power filter is proposed to compensate the harmonics and reactive power in power distribution system. The proposed system is composed of a 7 th harmonics-tuned passive filter and an active power filter with a Z-source inverter topology, while voltage source PWM inverter or current source PWM inverter are applied as the power converter topology of conventional...
This paper presents a model of the three-phase PWM inverter and a control strategy using dqO transformation to be employed in a grid connected photovoltaic generation system. The proposed system operates as an active filter capable of compensate harmonic components and reactive power, generated by the other loads connected to the system. To control the power between the grid and photovoltaic system...
