Different fault scenarios were tested using COMTRADE files, revealing important insights when comparing impedance protection and traveling wave approaches, to highlight the strengths and weaknesses of both protection approaches. A key finding of this study is the identification of a potential vulnerability when relying solely on alternating current side protection for faults on the direct current side. The results demonstrate that protection schemes based on incremental values or voltage memory can yield unreliable results, particularly in scenarios involving power swings and rapidly changing fault conditions (influenced by factors such as magnitude, trajectory, and rate of change).

The antenna is designed to be implemented on the wireless body area network. The newly proposed conformal antenna has then been tested on a virtually created human torso phantom to carry out its human on-body performance check. For in-depth analysis, five different bending angles, including the curved torso, and five different distances from the human body have been performed.

Despite its importance, many sites—especially isolated rural areas in need of sustainable energy sources—have a conspicuous dearth of information regarding these models. Significant errors can occur when choosing the incorrect TM for feasibility assessments or determining the optimum tilt angles (<em>β</em>) for solar collectors. A novel theory (Risky Index theory) for determining the least risky TM is introduced in this work. To evaluate and validate the proposed theory, eight commonly used TMs from literature, database platforms and software were chosen and tested on 133 sites with various climatic and geographical conditions in the Northern Hemisphere. The study concludes that risk index (RI) is <10 % for all models when the collector is facing south with low tilt angles (<em>β</em><40°). However, for 40°< <em>β</em><60° the RI rises above 15 %, and it becomes significant (RI<50 %) as <em>β</em> becomes close to vertical plane. The least risky TM was determined for each site.

However, to utilize these systems in promising applications such as the Internet of Things (IoT), wireless sensor networks, and to enhance power reception in telecommunications devices, it is necessary to design and develop rectifying antennas that operate across a broader frequency range. This paper presents a broadband rectenna system designed to harvest ambient radio frequency energy using a sandwich-type hybrid power combiner (HPC) for operation in the 2–18 GHz frequency range. The proposed integrated system incorporates a Vivaldi receiving antenna with a return loss of -13 dB across the entire frequency range and a three-layer sandwich-type power divider circuit design. The power divider features a coupling factor within the 3-dB range and a phase factor with an error margin of less than ±3°. The broadband power divider section is implemented without using lossy elements such as resistors and capacitors, employing only integrated tandem line techniques and simultaneous stripline coupling with an 8.34 dB coupling factor and equal 3 dB outputs on a Ro 4003c substrate. The proposed rectenna in this design achieves a power conversion efficiency of 72 % in simulation mode. This system maintains an efficiency of over 50 % across a load resistance range of 900 to 3000 ohms at an input power of 0 dBm. The sandwich rectenna operates with an efficiency of over 28 % in the frequency range of 2 to 18 GHz, with input power ranging from -15 to +15 dBm. The system functions effectively even at very low radiation power densities, such as 305 microwatts, achieving an efficiency of more than 40 %. results indicate that the proposed broadband rectenna serves as a power supply for modern devices in Internet of Things (IoT) applications.</div></div>","PeriodicalId":100488,"journal":{"name":"e-Prime - Advances in Electrical Engineering, Electronics and Energy","volume":"11 ","pages":"Article 100891"},"PeriodicalIF":0.0,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143177084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
