To ensure effective protection, a lightning protection system with optimally coordinated elements (air-termination system, earth-termination system, lightning equipotential bonding, surge protective devices for power supply and data systems) is required.What are surge protective devices (SPDs) in PV power plants?Surge protective devices (SPDs) (Figure 6) must be installed to protect the electrical systems in PV power plants. In case of free field PV system, high voltage impulses are induced on all electrical conductors and partial lightning currents flow into all sort of park cables (d.c., a.c. and data cables).
Do you need a lightning protection measure for a PV system?The German VdS 2010 brochure (Risk-oriented lightning and surge protec-tion) published by the German Insurance Association (GDV) requires that lightning protection measures (class of LPS III) be taken for PV systems > 10 kW of objects with alternative renewable power supply systems.
What is a free field PV power plant?capacity of some gigawatts, free field PV power plants are becom-ing an integral part of modern power supply systems in many countries. Today large-scale power plants with a capacity of 100 MW and higher are installed which are directly connected to the medium and high-voltage level. As an inte-gral part of a power supply system.
How a PV system is connected to a grid?Central Electricity Authority (CEA) has formulated regulations regarding technical standards of connectivity to grid. PV panel produces DC power. It may be fixed or tracking the sun to extract maximum power [3-4]. In a grid- tied system, AC power from inverter is fed to grid after synchronisation.
How to keep Earth resistance stable in PV power plant?To permanently keep the earth resistance stable over the many years of operation of PV power plant, the influences of corrosion, soil moisture and frost must be taken into account. Only the areas below the frost line must be considered for the effective earth elec-trode length.
Why do photovoltaic systems need a yield monitoring system?As an inte-gral part of a power supply system, photovoltaic systems must ensure stable grid operation.
