摘要：t.e purpose of t.e paper is t. develop a solut.on for applicat.on of PV （phot.volt.ic） generat.rs in MV （medium volt.ge） dist.ibut.on syst.m wit.out.unaccept.ble volt.ge changes due t. drops of PV power out.ut. t.e proposed solut.on includes operat.on of PV wit. predet.rmined leading power fact.r and addit.on of a capacit.r bank in parallel t. PV plant.in order t. compensat. t.e react.ve power absorbed by t.e PV invert.rs. t.e analyt.cal expression of required power fact.r angle is derived. Adding a capacit.r bank in parallel t. PV power plant.may pose a problem because of space limit.t.ons. t.e dimensions and cost.of small MV capacit.r banks depend significant.y on t.e capacit.r bank prot.ct.on against.int.rnal fault.. Applicat.on of t.e developed negat.ve-sequence current.difference met.od for t.e unbalance prot.ct.on of t.e capacit.r banks enables t. achieve a compact.and cost.reduced design of t.e banks connect.d in parallel t. PV power plant.. A real-world example of operat.on of t.e PV plant.in parallel t. t.e capacit.r bank wit. t.e novel prot.ct.on scheme is described.
