Solar power plants form a chain starting with 1000 V or 1500 V DC arrays and connected to the grid via inverters, transformers, and medium-voltage switchgear. In rooftop solar power plants, this chain is connected to existing plant panels. The arc flash study treats the AC and DC sections of this chain separately.<\/p>\n\n\n\n
IEEE 1584-2018 defines incident energy calculation for three-phase AC systems at voltages between 208 V and 15 kV and frequencies of 50\/60 Hz. Single-phase and DC systems are not included in the model; the standard only refers to methods in the literature (Ammerman, Das, Doan, Klement) for DC (clauses 4.11 and 4.12). The AC components of the solar power plant are calculated within this scope; the fault current contribution of the inverters is modeled using manufacturer data.<\/p>\n\n\n\n
DC sections (battery banks, DC side of inverters, PV arrays, DC distribution) are not calculated using IEEE 1584. In these sections, incident energy is calculated separately using DC methods from the literature and reported separately from AC results; the method and assumptions used are clearly stated in the report. In PV arrays, the short-circuit current is radiation-dependent and close to the operating current; therefore, the protection device on the DC side may not clear the fault quickly, and this is taken into account in the calculation.<\/p>\n\n\n\n
