ABSTRACT Real-time control systems are relying increasingly on digital discrete-time implementations instead of analog continuous implementations. The foremost challenge in a real-time system is to perform computations within very stringent time frames. Power electronics control system is such a real-time system. This work is concerned with the issues of emulating different electrical loads using power electronic converters. A real-time circuit simulator has been designed to emulate loads at significant power levels. In this work the load model is defined using open source circuit simulator as a front-end interface and a DSP-FPGA platform to emulate them in the back-end. This paper presents requirements of real time control systems and describes the digital hardware structure for a load emulator. In order to highlight the performance of the proposed system, experimental results of virtual load (three phase induction motor) are reported.

    ABSTRACT: A 3-phase regenerative electronic load to test shunt equipments such as active power filters and power conditioners at high power levels is presented in this paper. The electronic load is composed by two inverters with a common DC-bus. One inverter draws from the grid a configurable load current with the harmonic and imbalance desired levels, and the other one is used to inject the energy into the grid trying to minimize the losses, while the active filter performance is being tested. The control strategies and the current controller for both inverters are explained. Simulations and experimental results showing the proper operation of the electronic load to test shunt power conditioners are presented.
