IEC 62920-2017 光伏發(fā)電系統--電力轉換設備的電磁兼容性要求和試驗方法 Photovoltaic power generating systems – EMC requirements and test methods for power conversion equipment

This document specifies electromagnetic compatibility (EMC) requirements for DC to AC 
power conversion equipment (PCE) for use in photovoltaic (PV) power systems. 
The PCE covered by this document can be grid-interactive, which is termed as a grid 
connected power converter (GCPC), or stand-alone. It can be supplied by single or multiple 
photovoltaic modules grouped in various array configurations, and can be intended for use in conjunction with batteries or other forms of energy storage.  
NOTE A micro inverter is an example of a GCPC supplied by a single photovoltaic module. 
This document covers not only PCE connected to a public low voltage AC mains network or 
other low voltage AC mains installation, but also PCE connected to a medium or high voltage 
AC network with or without step-down power transformers. Requirements for the PCE 
connected to a medium or high voltage AC network are specified in this document. However, 
some requirements relevant to grid interconnection are addressed with other standards 
specifying power quality or their own grid codes in some countries. 
NOTE DC/DC converters used for PV systems are not yet covered in this document. They can cause electromagnetic interference due to conducted disturbances at DC ports. 
PCE is assessed with EMC requirements as a type test at a test site. This document provides 
test methods and test conditions for PCE as well as emission and immunity requirements, but 
not for photovoltaic modules and other balance of system components. 
When compliance with EMC requirements at the test site cannot be shown due to technical 
reasons of the test site, PCE can be assessed in situ, such as at the manufacturer’s premises or in the field where the PCE is assembled into a PV power system. However, only high frequency emission requirements for in situ assessment are specified in CISPR 11.dition 1.0 2017-07 INTERNATIONAL STANDARD NORME INTERNATIONALE colour inside Photovoltaic power generating systems – EMC requirements and test methods for power conversion equipment Systèmes de production d’énergie photovolta？que – Exigences de CEM et méthodes d’essai pour les équipements de conversion de puissance IEC 62920:2017-07(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2017 I
