Recently, fault indicators with communication function have been increasingly used in fault diagnosis of distribution networks. In this paper, an objective function which considers the reliability index of the distribution network and economic factors synthetically has been proposed for optimal placement of fault indicators in distribution networks, and binary particle swarm optimization algorithm...
DC-DC converters face an exponential growth in the context of the ever-increasing use of DC grids, namely at the home and business levels. In this domain, efficiency and reliability are of major concern. Solutions already available in the literature concerning fault-tolerant DC-DC converters do not consider the application of such converters in household environments and their constraints. To solve...
Condition monitoring and fault diagnosis are considered key features in order to increase the reliability and availability levels of wind turbine systems. Accordingly, this paper proposes a single fault diagnostic algorithm for multiple IGBTs open-circuit faults and current sensor faults in direct-driven wind turbines, based on permanent magnet synchronous generators with full-scale back-to-back converters...
In order to elevate equipment-oriented traditional asset management to system-oriented advanced asset management (AAM) decision-making for smart power grid, for the problem that influence of different positions of the equipment in network topology on system reliability is not taken into consideration in retiring strategies of transformer LCC (life cycle cost), which may cause overestimation or underestimation...
In this paper, the concept of P-Z-N distributed bipolar DC system is proposed in differentiation with existing PN distributed bipolar DC system. Such configuration enables each pole with independent operation capability and shows higher system reliability. Operation of P-Z-N distributed bipolar system involves coordination of PZ sub-microgrid and ZN sub-microgrid. In comparison with voltage balancer...
Hybrid AC-DC systems are expected to flourish rapidly as part of the transition from conventional grid to smart grid. Effective detection, classification, and mitigation of faults in hybrid systems require accurate modelling of the entire system as a whole, and its components as well. Moreover, precise computation of fault current is an indispensable part of any fault management scheme. Such modelling...
