Their fast response offers potential benefits for power system stability enhancement and allows utilities to operate their transmission systems even closer to their physical limitations, more efficiently, with improved reliability, greater stability and security than traditional mechanical switching technology. The unified Power Flow Controller (UPFC) is the most comprehensive multivariable device among the FACTS controllers. According to high importance of power flow control in transmission lines, new controllers are designed based on the Elman Recurrent Neural Network (NEWELM) and Neural Inverse Model Control (NIMC) with adaptive control. The Main purpose of this paper is to design a controller which enables a power system to track reference signals precisely and to be robust in the presence of uncertainty of system parameters and disturbances. The performances of the proposed controllers (NEWELM and NIMC) are based neural adaptive control and simulated on a two bus test system and compared with a conventional PI controller with decoupling (PI-D).

The electronic protection was design into low capacity PLC. The paper presents the designs and analysis of complex electronic protection for general purpose low-voltage three-phase induction motors. The electronic protection has Hall transducers and conversion electronic devices for AC currents to DC voltages, AC voltages to DC voltage, temperature to DC voltage, a low capacity PLC, switches, motor’s power contactors, and signalling lamps has been developed.

There is always demand for high speed, seamless data connectivity. But it is a well-known fact that the increase in speed always makes the power consumption higher. Also while attempting to cater to the need of connectivity to a remote location, the major bottleneck is the availability of power. Hence incorporating self-sustainability to a wireless network is becoming the need of the hour. Radio frequency (RF) energy harvesting (EH) is gaining much attention in contemporary communications in this context. In the design of an EH system, the high frequency rectifier plays a significant role. Apart from several design hurdles that exist in a high frequency rectifier, to attain a high percentage conversion efficiency (PCE) at lower input power is the primary design challenge. This paper presents a design of a modified transmission gate (TG) based high frequency rectifier with two substrate voltage compensation techniques, viz. capacitor and MOS based compensation for RF EH system.The proposed capacitor and MOS based techniques enable the rectifier to achieve a PCE upto 86% and 92% at -5dBm respectively in its single stage implementation. This can be claimed to be the highest in-class efficiency as compared to recently published works. The frequency responses with both the techniques depict a wide band performance covering all popular wireless bands. The dynamic power dissipations (DPD) observed are 12nW and 16nW at -5dB, whereas the leakage power (LP) is 20x10-51W and zero respectively. Further such an performance are obtained using minimal number of transistors, viz. 4 and 5 respectively.","PeriodicalId":202814,"journal":{"name":"WSEAS TRANSACTIONS ON ELECTRONICS","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116606318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
