Abstract :
A load simulator with power-recovery capability is proposed. The load simulator consists of a converter-inverter set with a DSP controller for system control and PWM pulse generation. The converter operates as a universal load to model the linear load and the nonlinear load, while the inverter feeds the energy back to the power source with harmonic compensation. The operation of the proposed system has been analysed through simulations with PSCAD/EMTDC, and the feasibility of hardware implementation confirmed through experimental work with a 20 kVA prototype. The load simulator can save the electrical energy used in testing performance of the power quality compensator and power equipment
