Accurate PV system simulators are implemented with expensive software platforms using paid irradiance *** main purpose of this paper is to develop and validate a PV system simulator,beginning with a solar cell parameter extraction model,then test and validate long-termIrradiance data using free online source(Typical Meteorological Year TMY in(PVGIS)European website),and finally building full solar generator simulator to run in working real *** results with Accurate Paid PV simulators(which use theMuneer model)showed good accuracy of the proposed *** flow starts with the Irradiance model’s data processing,then solar cell 5 parameters model data processing(to extract cell parameters),and finally full system *** coding programs in real working conditions are used for *** of solar cell parameter extraction show 99.6%to 99.99%matching with data sheet and cell performance under standard test *** simulation output shows 8%less yearly generated energy compared to the PVGIS 2022 long-term simulation(hourly basis(one-year time)).This is due to incident energy variations(between the years 2016 and 2022)of 4.02%.The novelty of the algorithm is the methodology,as it tests irradiance data on an hourly basis and validates results for a whole continuous ***,the 5-parameter solar cell model is used to be validated in long term analysis,not only STC conditions and could be applied on any PV solar *** algorithm and block diagramused are scalable,modular,and interchangeable with similarmodels to be *** simulator could test severalmethods andmodels in solar pv technology.

An SDL Design and Implementation of a Radiation Monitoring Network Using WCDMA

引用

通讯和计算机（中英文版） 2012年第5期9卷 602-612页

Recently, nuclear material monitoring becomes very important especially in the emerging nuclear regions. In this paper, the Universal Mobile Telecommunication System (UMTS) network is proposed to handle the communication between local Dose Rate Measuring units and Central Monitoring unit. To achieve this purpose, a scheme is proposed to compute dose rate and transfer its values in conjunction with time stamp and location to the Central Monitoring unit of the Network using Wide Band Code Division Multiple Accessing (WCDMA) system. Specification and Language (SDL) language is used to design, implement and simulate the proposed scheme. Simulation results show the functionality of this scheme.
