1 Scope
The purpose of this part of IEC TS 63106 is to provide recommendations for Low Voltage (LV) DC power simulators used for testing photovoltaic (PV) power conversion equipment ( PCE ) to utility interconnection or PV performance standards.
NOTE Low Voltage refers to DC voltage 1 500 V and less.
In this document, the term “ DC power simulator ” refers to any source that is used during testing to provide DC power to the Equipment Under Test ( EUT ). That includes, but is not limited to, PV array simulators designed to simulate the DC output I-V curve of a photovoltaic array operating in
real-world conditions.
This document primarily addresses DC power simulators used for testing of grid-interactive PCE , also referred to as grid-connected power converters (GCPCs). It also addresses some
uses of DC power simulators for testing stand-alone and multi-mode PCEs .
There are many types of tests that can be conducted by utilizing a DC power simulator . Certain tests require the use of a PV array or PV array simulator , such as measurements of the PCE ’s PV input static and dynamic characteristics related to maximum power point tracking, while other tests may be appropriate to conduct with a static DC power
supply. Test requirements and procedur...
