新能源及智能电网研讨会 上海海事大学汤天浩教授主持 PCIM Asia诚邀您的参与 Wednesday afternoon, 28June 2017 Meeting room 2 in the Floor B2 of Shanghai World Expo Exhibition and Convention Center Tianhao Tang Shanghai Maritime University, China
Xing Zhang Hefei University of Technology, China Implementation of Super Real-time Simulation for Power Electronic Systems To fast develop the power electronic systems (PES) for diversified application requirements, the need for new simulation methods are increasing. In this paper, a simplified and universal method for realizing super real-time simulation is presented so that the long term performance of a PES can be evaluated in a specific short-time by proportionally accelerating advancement of simulation time. The proposed method is validated by taking a PV generation system as an example to show the implementation process. A minute-day simulation is performed to demonstrate the energy balance and smooth dynamic behaviors of the PV generation system for a typical day.

To match the solar market demand, it is necessary to investigate high power solar inverter configuration with reduced DC bus voltages as higher DC bus voltages affect the reliability of the inverter. In this work a new inverter configuration with reduced DC bus voltages is proposed. Through proposed configuration, the total power is processed to grid with almost half of the DC bus by operating inverter modules of configuration with 180 phase shift though devoted PWM technique. A derived PWM technique ensures to derive the constant grid voltage irrespective of DC bus voltage variation due to irradiation mismatch.
