Development of a Test Platform for Grid-Connection PV Systems

This paper describes this development of a test platform of a grid-connection PV station. Essentially this entire platform involves the integration of a Personal computer (PC), a Dc power source, a power analyzer, an AC load and an analog grid to create a grid-connection PV system and to test. This new system boasts of high accuracy measurements coupled with the commercial viability of low cost. In the test system, various testing equipments have been controlled by the computer. This control interface has been developed by utilizing Labview software, which forms the programming backbone of inter-instrument communication via RS232 bus and Ethernet.
