Abstract
This paper presents a computer simulation model (in the MATLAB/Simulink environment) of a photovoltaic system disturbed by a 1.2/50 µs voltage surge pulse, while operating as part of the fixed system of an intelligent building. The tested part of the system consisted of a single PV module and a single-phase DC/AC voltage source converter provided with a maximum power point tracking system. The simulation of the test performed in accordance with the IEC 61000-4-5 standard required the development of a model of a surge waveform generator and a model of a coupling/decoupling network. The 1.2/50 μs voltage surge pulse was introduced into the system from the power grid side. During the test significant changes in the value of the AC voltage and current were found in the DC/AC converter system. The results of the computer simulation tests were verified with measurements performed in an accredited electromagnetic compatibility laboratory using the instructions specified in IEC 61000-4-5. The MATLAB/Simulink environment was proved as a useful tool of the assessment of effects of conducted electromagnetic disturbances on electronic/electric devices.
Highlights
The rapid development of the electronics industry at the turn of the last twenty years has been caused the issue of electromagnetic compatibility (EMC) plays a very important role.Pursuant to the electromagnetic compatibility directive [1], every electric or electronic product placed on the market must fulfil the requirements of general and subject standards.The equipment manufacturer is required to assess the product’s compliance with the standards

The rapid development of the electronics industry at the turn of the last twenty years has been caused the issue of electromagnetic compatibility (EMC) plays a very important role. Pursuant to the electromagnetic compatibility directive [1], every electric or electronic product placed on the market must fulfil the requirements of general and subject standards. The equipment manufacturer is required to assess the product’s compliance with the standards. The essential product evaluation requirements include: (a) iations. An electrical or electronic device must not generate electromagnetic disturbances above a level that would cause incorrect operation of other devices in this electromagnetic environment, An electrical or electronic device should have such a degree of immunity to electromagnetic disturbances that causes its properly operation during use [2,3,4]
