This study was carried out at Gas platform (unit No 30) of Skikda refinery Algeria, with the aim of predicting and estimating the effects of major explosions in the propane and butane Splitter column and estimating the possible human and environmental consequences of the containment loss. The methodology developed here is based on a combination of HAZOP presentation and PHAST tool. First, HAZOP is used to capture the responsible derivations of operating parameters to produce the worst consequences. Related Causes, safety barriers and some recommendations are carried out in a HAZOP sheet which represents all of that. Then the major scenarios detected by the worst consequences have been studied and modeled by PHAST software. The modeling process is completed by simulating the principal effects (Jetfire, BLEVE, UVCE) resulting from two scenarios in the form of two potential leaks on the bottom and the head of a gas separator column containing butane and propane respectively. The results are shown on the region map to indicate the exact threaten zones. Finally, a comparison in terms of effects between the two scenarios is performed and some conclusions are extracted.\u0000 ","PeriodicalId":153848,"journal":{"name":"Algerian Journal of Signals and Systems","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117294072","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}

Traditional electricalenergy generation approaches which usually rely on oil and its derivatives, produce different kinds of pollution in addition to being expensive to implement and maintain. And most important, they are exhaustible on the long run. The sun is an unlimited source of energy for humanity around the world and a competitive energy with strong potential. The solar systems technology offers a promising method for the large scale use of solar energy in the southern zone of Algeria. The magnitude of solar radiation is the most important parameter for sizing these systems. This study presents a techno-economic feasibility evaluation for an installation of a stand-alone PV system which covers the electric demand of 20 houses in the province of Tindouf located in the South-West of Algeria. The aim is to select the appropriate components and see the results of the simulation using the hybrid simulator iHOGA, which include the total cost, CO2 emissions and their impact on the environment.","PeriodicalId":153848,"journal":{"name":"Algerian Journal of Signals and Systems","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133022674","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}

Since, load frequency and voltage stability is an important power quality index in power system, any sudden load disturbance will cause the system load frequency and voltage deviation, and as the power system becomes more complex. However, the stability and reliability of the smart power grid are facing great challenges caused by the intermittency and randomness of renewable energies. Nowadays, it is necessary to find a more appropriate control strategy and techniques. Due to the superior anti-interference and anti-coupling ability of the active disturbance rejection control (ADRC), novel applications of this control technique have been developed in smart system. This paper presents firstly a synthesis of ADRC and then it discusses some important applications of ADRC in this field.","PeriodicalId":153848,"journal":{"name":"Algerian Journal of Signals and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123829271","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}

The proposed UPQC is able to mitigate source current harmonics and compensate all voltage disturbances. It is designed by the integration of series and shunt active filters (AFs) sharing a common DC bus capacitor. The DC voltage is maintained constant using proportional integral voltage controller. The synchronous reference frame (SRF) theory is used to get the reference signals for the shunt APF and the power reactive theory (P-Q theory) for the series APF.Conventional control schemes require complex calculations, the use of intelligent systems help to reduce the control system size and the operation complexity. The shunt and series active power filter (APF) reference signals derived from the control algorithm are injected in Fuzzy and Ann intelligent controllers to generate switching signals. The performances of the proposed UPQC system are evaluated using Matlab-Simulink software and SimPowerSystem Toolbox under various operation conditions. The simulation results show the performance of the proposed UPQC based on intelligent controllers to improve the power quality in steady and transient conditions operation.","PeriodicalId":153848,"journal":{"name":"Algerian Journal of Signals and Systems","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114484494","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}

However, the analysis of simulation using realistic computer codes like RELAP5/Mod3.2 will help understand thermal-hydraulic behavior of an installation during normal and accidental conditions. In a steam boiler operation, it is very important to evaluate numerous accident scenarios under real plant conditions. One of the main accidental transients is tube rupture of steam boiler. The main objective of this study consists toinvestigate the behavior of an industrial steam boiler installed in the complex of natural gas liquefaction (LNG) at Skikda in Algeria during feed water line break accident. A RELAP5 model was set up to simulate the entire system, the model represents all steam boiler components to be suitable for the analysis of the several accidents. The control and regulation systems are also considered. The model was qualified against the steam boiler data at steady-state conditions. As seen from the results, a good agreement was obtained. The transient simulation results show that the thermal-hydraulic code correctly predicts the behavior of the main steam boiler parameters and how the control system, when required, can successfully mitigate the accident.","PeriodicalId":153848,"journal":{"name":"Algerian Journal of Signals and Systems","volume":"30 2-3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132288634","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}
