The deployments of inverter-interfaced distributed generators (IIDGs) in medium voltage distribution networks may cause undesirable trips or tripping failures conventional two-terminal current differential protective relays. It is economically and technically unfeasible to reconfigure large numbers time-synchronized sampling clocks communication channels for each terminal inside the protected zone. In this paper, a more accurate IIDG mathematical equivalent model established that considers...
Inverter-Interfaced Distributed Generation (IIDG) connected to distribution network with a teed line may cause protective relay tripping failure even using conventional current differential protection, which is regarded as one of the most effective protection for distributed generations. Therefore, impacts IIDGs on traditional pilot analyzed firstly in this paper. Next, fault characteristics IIDG are introduced and model established, viewed source controlled by positive-sequence voltage at...
Walnut shell breaking is an important aspect of post-harvest processing. However, shell-breaking results differ significantly from ideal uniaxial compression results. In this paper, the effect multipoint loading on walnut mechanism by combining FDEM with cohesive elements was investigated. The model for walnuts created using micro-X-ray CT scans and experimental data. Simulation parameters describing mechanical properties were calibrated through modeling experiment. point locations...
The quick response of inverter integrated distribution generation (HDG) source under fault makes the equivalent circuit sequence network different from traditional power system. Based on control strategy and model distributed (IIDG) fault, IIDG can be taken as voltage or current in sequence-network. With analysis for micro-grid with multi-DG integrated, this paper presents a novel short-circuit calculation method islanded based master-slave control. proposed is HDG considering unbalanced...
When a complex multi-line single-phase grounding fault (SPGF) occurs in low resistance system, zero-sequence currents the faulty feeders would suffer significant decrease compared to situation when single-line SPGF occurs, which will reduce sensitivity of current relay and may cause tripping failure severe cases. Therefore, analysis for was carried out this paper firstly, then some important rules were revealed. On basis, novel adaptive protection scheme proposed, by can be compensated its...
Wedged link is widely applied to circular cabin section linking structure for the advantages such as reliability, convenient installation and removal well high space utilization ratio.Generally, wedge block strength computed using engineering method.However, transfer load of must be obtain firstly, which usually difficult.The adoption finite element method makes it possible simulate complex transferring path between body, thus obtaining a more comprehensive integral structural stress...
