DIgSILENT PowerFactory Tutorial: HVDC-LCC Connection and Configuration | Lecture 44 This lecture demonstrates the complete workflow for installing and configuring a Line-Commutated Converter (LCC) HVDC link in DIgSILENT PowerFactory using the IEEE 39-bus test system. The tutorial addresses a realistic transmission planning scenario in which long AC lines experience significant overloading and voltage drops, and shows how an HVDC-LCC solution can be implemented to relieve congestion, reduce losses, and provide electrical isolation between subsystems. Key topics covered include: • Identification of overloaded AC corridors through load-flow analysis on the 39-bus network • Replacement of a selected AC line with an HVDC-LCC interconnection (unidirectional power transfer) • Configuration of rated active power, AC-side voltage, no-load losses, and DC voltage parameters • Selection of control modes: Power Dispatch Control (PDC) at the rectifier and Voltage DC Control (VDC) at the inverter • Calculation of the appropriate DC line-to-line voltage using PowerFactory technical references and resolution of load-flow convergence issues • Incorporation of realistic loss modeling and validation of successful 600 MW power transfer By the end of the tutorial, viewers will understand how to model HVDC-LCC systems in PowerFactory, correctly set converter controls, and evaluate the technical and operational benefits of HVDC versus long AC transmission. The approach is directly applicable to interconnection studies, corridor reinforcement, and multi-area system analysis. This content is intended for power system engineers, transmission planners, researchers, and graduate students working with high-voltage transmission modeling and modern grid interconnection technologies.
