Low-Voltage Hardware-in-Loop Test Model Using Real-Time Digital Simulator for Single-Phase Converter

This paper describes the development of low-voltage model of different stages of power converter for making the performance evaluation of it under different operational conditions. The operational conditions vary depending on the network to which the converters are to be interfaced—the types as well as the number of operational conditions to be considered are maximum, in particular, when they are to be tied with micro-grid or smart grid systems. The remedial measures of the effect of these changes in operational conditions are to be incorporated into the low-signal control schemes for its reliable, secured and long-term operation. The various real system operational conditions are simulated in real-time digital simulator (RTDS) and the prototype of the developed hardware in low voltage level is interfaced with it.
