Scope

This part of GB/T18802 gives guidelines for selection, installation and coordination of SPDs connected to photovoltaic systems whose AC side voltage rms value does not exceed 1000V (50 Hz or 60 Hz) and DC side voltage does not exceed 1500V. The scope of a photovoltaic system extends from a photovoltaic array or a group of interconnected photovoltaic modules to include related cables, protection devices and inverters, all the way to the connection point of the distribution cabinet or the public grid connection point. This section considers the following SPDs used in different locations and different types of photovoltaic systems: --- photovoltaic systems located on top of buildings; --- photovoltaic systems located on the ground, similar to ground power stations, which are characterized by the use of multi-point grounding and A meshed grounding system. The term "photovoltaic system" is used to refer to the above two photovoltaic systems; the term "photovoltaic power station" is only used to refer to a power system located on the ground that can be expanded arbitrarily and has multiple grounds. For the protection of photovoltaic systems containing energy storage batteries, additional requirements may need to be met. Note 1: GB/T 16895 (all parts), GB/T 21714 (all parts) and IEC 61643 12 are also applicable. Note 2: This section only deals with SPDs, and does not involve surge protection components integrated in the equipment [for example, in inverters, power conversion equipment (PCE)].
