Development of standard test procedures for electromagnetic interference (EMI) tests and evaluations on photovoltaic components and plants

Objective



OBJECTIVES OF THE PROJECT

On the 1 st January, 1996, new laws on the 'electromagnetic compatibility of appliances (EMC)' came into force as legal basis for the electromagnetic compatibility in most countries of the European Union. There is uncertainty among representatives of the affected trades on the specifications which have to be met by components and systems (especially for PV). The objective of the 'PV-EMI-Project' is the realization of a standardized European approach towards the Electromagnetic Compatibility of Solar Photovoltaic ('PV') Systems by means of elucidating the legal situation, developing measuring concepts, doing concrete sample measurements and realizing information dissemination to standardization committees and final users (industry, SMEs, plant owners).
TECHNICAL APPROACH

The technical approach is to reconcile legal pretensions on EMC and safety aspects with specific technical features of PV systems and components by: - collecting a survey over EC EMC standards applicable to PV systems and plants. The technical demands resulting from the standards and regulations will be adapted to PV systems and basic requirements for measurements will be identified.
- identifying and developing measuring concepts to prove, that PV systems comply with essential protection requirements,
- discussing the relation between EMC measures and other safety concepts, especially by elucidating the influence of lightning and overvoltage protection measures to the EMC behaviour,
- performing sample measurements to prove the applicability of the developed measuring concepts and to produce general examples as orientation. - preparing recommendations on guidelines, forms and information sheets for use of standardization committees and application by PV specialists and owners.

EXPECTED ACHIEVEMENTS

The achievements of these objectives should result in concrete benefits for national and international standardization committees, PV industry, installers and owners of PV systems and components. It is expected that after the end of the project recommendations for modifications or specifications of existing standards and regulations will arise, which need to be processed by standardization committees to get part of the harmonized European legislation.
