Topologies of VSC based MTDC system has been reconnoitered. A Novel two wind farms and one platform (2WF-1PF) topology has been proposed. MTDC link topologies have been analyzed and likened based on techno-economic criteria's: number of HVDC circuit breakers, length and capacity of HVDC circuits, number of offshore and onshore platforms, flexibility, redundancy and utilization of HVDC links. Technical...
This paper presents a topology for dc grids which enables very robust dc fault protection with moderate costs, good operating flexibility, and simple controls. It is postulated that radial dc systems are best suited for limited-size local dc grids. Radial topology enables robust and fast protection selectivity using only local signals and exploiting the advantages of hybrid dc circuit breakers (CBs)...
Electrical power system is an intricate network of transmission lines and its complexity is consistently increasing with induction of distribution generation (DG) which is nonlinear in nature. One of major problem with remotely generated electrical energy is of reliable transportation to ever increasing load center. A solution must be capable to deal with controllable components of power and one strong...
This paper provides a discussion on future direct current (DC) network development in terms of system protection under DC-side fault scenarios. The argument between appropriate DC circuit breaker and new DC fault-tolerant converters is discussed after a review on DC technology development and bottleneck issues that require proper solutions. The overcurrent/cost curve of power-electronic DC circuit...
