• Robust sensorless commutation control. • External speed reference. • Overcurrent detection/protection. • Basic speed controller included. • Full source code in C. • Source code can be adapted to a new motor by changing parameters. • Several I/O pins/peripherals not used for motor control. Can be used for other purposes, such as status LEDs, communication or user input. • Works without modific...

in this paper two different rateless transmissionschemes are developed. in the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...

The relative protective devices are cascaded in a proper sequence with min/max coordination time margin (CTM) to minimize the outage area of network case fault condition. This manuscript addresses new methodology based on gorilla troops optimizer (GTO) produce best automated settings for overcurrent relays. In GTO, exploration and exploitation phases realized using five methodologies. Three the...

In the last few years, integration of renewable distributed generation (RDG) in electrical distribution network (EDN) has become a favorable solution that guarantees and keeps satisfying balance between production consumption energy. this work, various metaheuristic algorithms were implemented to perform validation their efficiency delivering optimal allocation both RDGs based on multiple photo...

In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

The hybridization of PSO for the Optimal Coordination Directional Overcurrent Protection Relays (DOPR) IEEE bus system proposes a new method coordinating directional overcurrent protection relays in power systems. combines hybrid particle swarm optimization (HPSO) algorithm and heuristic to find minimum total operating time with speed accuracy. proposed is tested on 4-bus, 6-bus, 8-bus systems,...

For the Taiwan Power Company (Taipower), the margins of coordination times between the lateral circuit breakers (LCB) of underground 4-way automatic line switches and the protection equipment of high voltage customers are often too small. This could lead to sympathy tripping by the feeder circuit breaker (FCB) of the distribution feeder and create difficulties in protection coordination between...
