What is this BS EN IEC 62920 - Power conversion equipment about?
BS EN IEC 62920 discusses photovoltaic power generating systems with a focus on EMC requirements and test methods for power conversion equipment (PCE). BS EN IEC 62920 specifies electromagnetic compatibility (EMC) requirements for power conversion equipment (PCE) (e.g., DC to DC, DC to AC, and AC to DC) for use in photovoltaic (PV) power systems with or without DC-coupled electrical energy storage devices.
The PCE covered by BS EN IEC 62920 can be grid-interactive, which is termed as a grid connected power converter (GCPC), or stand-alone. BS EN IEC 62920 are 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.
PCE is assessed with EMC requirements as a type test at a test site. BS EN IEC 62920 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.
Who is BS EN IEC 62920 - Power conversion equipment for?
BS EN IEC 62920 on power conversion equipment is useful for:
- Photovoltaic power generating systems manufacturers
- Power conversion equipment manufacturers
- Power generation plants
- Water management bodies
Why should you use BS EN IEC 62920 - Power conversion equipment?
PCE is indispensable for solar photovoltaic power energy systems in order to convert the DC electric power energy generated by solar photovoltaic panels into AC or DC electric power and to feed the AC power energy into the AC mains network or loads. PCE consists of DC to DC, DC to AC, or AC to DC converters and forms systems with or without DC-coupled electrical energy storage devices.
BS EN IEC 62920 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 BS EN IEC 62920. However, some requirements relevant to grid interconnection are addressed with other standards specifying power quality or their own grid codes in some countries.
