摘　　要：Unified power quality conditioner(UPQC)is a power electronics device consisting of a series active filter(Se AF)and a shunt active filter(Sh-AF)connected in parallel through a DC-link circuit to overcome power quality problems,ie.,voltage sag,voltage swell,and non-linear(NL)load.The weakuess of the UPQC is that it cannot function normally if the Se AF and/or Sb-AF fail,and the devices are uable to transfer active power to the load in the event of an interrupt voltage at the source.This paper proposes a novel configuration of a dual UPQC supplied by a dual photovoltaic PV),hereinafter referred to as 2UPQC2PV,to improve the power quality performance of a single-pbase 220 V/50 Hz distribution system.The 2UPQC 2PV configuration is proposed to anticipate the possible failure of both inverters in one of the UPQC circuits.The PV array replaces the DC-link capacitor to maintain its voltage counected to the DC-link of the UPQC constant while at the same time supplying active power to the load during.an interruption voltage.The dual-fuzzy Sugeno(dualFS)method is used to overcome the weakuess of the dual-proportioual-integral(dual-PD)control in determining the optimum paramneters of proportional and integral comstants.There are three disturbances simulated in each-of 2UPQC-2PV and 1UPQC-1PV using dual-FS and dualPI,i.e,Case(S Sag-NL),Case 2(S-Swell-NL),and Case 3(S-Inter-NL).Each UPQC-PV combination using FS control is compared with PI control resulting in a total of sir cases.The 2UPQC-2PV configuration with dual-PI and dual-FS controls,in the three fault cases,is able to produce higher voltage changes than the 1UPQC 1PV coufiguration.For the 2UPQC-2PV configuration in the three fault cases,Dual-FS control is able to produce lower THDs of load voltage and source current,than the dual-PI control,while meetings the limits of IEEE 519 Standard.In Case 3,the configuration of 2UPQC-2PV using the dual-FS method,is capable of delivering the active power of the load close to that in Case 1.
