Water droplets on the surface of silicon rubber were investigated under the influence of non-uniform electric fields. Several parameters of water droplets were investigated, such as the positioning of the droplets regarding the electrodes. The most striking conclusion is that the flashover voltage and electric field distribution depends on the positioning of the droplets from the electrodes.
In this paper an approach is developed for the online diagnosis of timed discrete events systems, the formalism used is the labeled timed Petri nets. We have introduced a new concept is: enriched set of possible states. In addition to online diagnosis our approach allows us to avoid the combinatorial explosion of states.
Safety instrumented systems (SIS) are designed to prevent the occurrence or mitigate the consequences of potentially hazardous events. The failure of SISs to achieve their assigned functions could result in huge consequences with respect to both (i) the safety of the monitored system (dangerous failures) as well as (ii) its production availability due to false trips (safe failures). The aim of this...
This paper presents Direct Power Control (DPC) based on instantaneous power theory is presented. The simulation of a grid connected five level inverter via an inductive filter with a new direct power strategy is used. However, this control method is similar to the classic DPC method, in which used triangles instead of the sectors. Furthermore, the regulation of DC link without interfering the hysteresis...
This paper present multi-objective optimization for optimal multi DG location and sizes in radial networks. The objectives fitness considered are minimize active power losses and maximize voltage stability. The hybrid technique based on NSGA-II and Fuzzy logic is used to determine optimal solutions. The proposed technique is tested on diversesizes of IEEE distribution network (10bus, 33bus and 85bus)...
