Hil evaluation of control unit in grid-tied converters

Abstract

Hardware-in-the-loop emulation is poised to become unsurpassed design tool for development, testing, and optimization of real-time control algorithms for grid connected power electronics converters for distributed generation, active filters and smart grid applications. It is strongly important to examine and test how grid connected converters perform under different operating conditions including grid disturbances and faults. In that sense, converter's controller is a key component responsible for ensuring safe and high-performance operation. This paper demonstrates an example how ultra-low latency and high fidelity hardware-in-the-loop emulator is used to easily, rapidly and exhaustively test and validate standard control strategy for grid connected power electronics converters, with-out need for expensive hardware prototyping and laboratory test equipment.
