Photovoltaic system emulator

This could be performed with accuracy in the laboratory without having PV array by using the emulator. This paper presents the PV emulator using real-time algorithm execution of the PV array mathematical model and generating the scaled output power from the AC-DC power supply. The generic PV model is simulated in LabVIEW and interfaced to the real world through a data-acquisition system. The GUI interfaced template allows the commercial PV arrays details to be configured. The actual field conditions i.e. varying temperature and irradiations are emulated by the corresponding sensor equivalent voltages. This laboratory prototype is tested with real-time execution of PV model for the steady state and dynamic operating conditions. The performance of MPPT based Golden Section Search algorithm is evaluated using the proposed emulator.

PERFORMANCE COMPARISON OF PWM SCHEMES OF DUAL-INVERTER FED FIVE-PHASE MOTOR DRIVES

The structure is simple and offers a lot of advantages. However, the development of suitable PWM schemes is more complicated, due to the availability of a large number of switching states and existence of the multiple two-dimensional planes. An overview of attempts to develop suitable modulation techniques for the dual-inverter fed five-phase machine drives recognizes that progress has been made over the past few years. This paper presents a performance comparison of three PWM schemes of the dual-inverter fed five-phase, open-end winding motor drives. The quality of the phase output voltages are compared and the adequate analyses are provided. The simulation results show that the Carrier Based Phase Disposition (PD) PWM scheme enables generation of the most excellent output voltage among the three PWM schemes. The Total Harmonics Distortion (THD) of the output voltages generated by the carrier based PWM scheme reduces by 65% and 15% on average compared to the THD of the output voltages produced by the URS PWM scheme and the decomposition PWM scheme respectively.

Integrated battery controller for distributed energy system

The BESS is integrated in parallel with the full wave bridge converter into the distributed energy system network. In a normal operating mode, the BESS serves as a power conditioner as well as an active power filter in a distributed power system network. This work presents BESS controller which is designed for regulating the state of charge of the batteries and also to manage the active power in a distributed power system network. The off peak load energy is used to recover the batteries' state of charge through the BESS controller. In this BESS controller, the constant currenteconstant voltage (CCeCV) mode is used and it helps to keep the batteries' state of charge conditions for improving the reliability of the distributed power system system. This control strategy is incorporated into the main converter. The controller helps in managing the phase, amplitude and waveform of the current and voltage on the distributed power system network. The controller ensures the power quality and also assists in improving the power factor with respect to the utility for the intermittent distributed generation as well as the load. In this article, the test results of a prototype system are presented, which validates the proposed controller strategy of BESS in a distributed power system network.
