摘　　要：With the rapid expansion of offshore wind farms(OWFs)in remote regions,the study of highly reliable electrical collector systems(ECSs)has become increasingly important.Post-fault network recovery is considered as an effective mea-sure of reliability enhancement.In this paper,we propose a smart switch configuration that facilitates network recovery,making it well-suited for ECSs operating in harsh environ-ments.To accommodate the increased complexity of ECSs,a novel reliability assessment(RA)method considering detailed switch configuration is devised.This method effectively identi-fies the minimum outage propagation areas and incorporates post-fault network recovery strategies.The optimal normal op-erating state and network reconfiguration strategies that maxi-mize ECS reliability can be obtained after optimization.Case studies on real-life OwFs validate the effectiveness and superi-ority of the proposed RA method compared with the traditional sequential Monte-Carlo simulation method.Moreover,numeri-cal tests demonstrate that the proposed switch configuration,in conjunction with proper topology and network recovery,achieves the highest benefits across a wide range of operating conditions.
