Power Generating Modules Field Testing Concepts for Verification of Compliance with Operational Requirements

The paper deals with innovative concept of power generating module field testing, with focus on PV inverters belonging to power category A, using a virtual testing process as a complementary method to compliance verification employing a power system simulator. The paper starts with a brief review of currently used methods and state of art pointing to approach for the virtual testing implementation. In next, experimental set-up using National Instrument hardware based control system with custom control loop in LabView software is introduced and obtained test results are evaluated to assess the proposed concept performance. Finally, the virtual testing deployment advantages and challenges are discussed.
