Real-Time Monitoring System for a Utility-Scale Photovoltaic Power Plant

There is, at present, considerable interest in the storage and dispatchability of photovoltaic (PV) energy, together with the need to manage power flows in real-time. This paper presents a new system, PV-on time, which has been developed to supervise the operating mode of a Grid-Connected Utility-Scale PV Power Plant in order to ensure the reliability and continuity of its supply. This system presents an architecture of acquisition devices, including wireless sensors distributed around the plant, which measure the required information. It is also equipped with a high-precision protocol for synchronizing all data acquisition equipment, something that is necessary for correctly establishing relationships among events in the plant. Moreover, a system for monitoring and supervising all of the distributed devices, as well as for the real-time treatment of all the registered information, is presented. Performances were analyzed in a 400 kW transformation center belonging to a 6.1 MW Utility-Scale PV Power Plant. In addition to monitoring the performance of all of the PV plant’s components and detecting any failures or deviations in production, this system enables users to control the power quality of the signal injected and the influence of the installation on the distribution grid

The Investigation Of Okhissa Dam Using A Real-Time Monitoring System

According to the National Inventory of Dams (NID), the United States has approximately 87,000 dams. Many of these dams are more than 50 years old and need to be investigated to ensure their safety to the public. A real time monitoring system can obtain a more reliable evaluation of the dam’s performance as well as serve as an early warning system to inform officials of a dam’s condition. Okhissa Dam was selected for investigation using a real-time monitoring system. Okhissa Dam is located in a region that contains both a phreatic aquifer and a confined aquifer. Prior to this investigation of Okhissa Dam artesian conditions were present. The Artesian conditions were alleviated by placing additional fill material on the downstream side. It is presumed these high piezometric water levels resulted from pressure in the aquifer due to communication from Okhissa Lake. The goal of this investigation is to determine if the reservoir is influencing the piezometric water levels and how these water levels can be used to evaluate slope stability and provide a real time warning. The comparison of water levels recorded by the shallow and deep piezometers to reservoir water levels show the reservoir has no influence on the shallow phreatic aquifer. However, the reservoir water levels are potentially affecting the deeper confined aquifer water levels. The largest fluctuation in the groundwater levels occurred with the intentional reduction of two feet in the reservoir level on December 16, 2014. This would have been the best predictor of variation in groundwater elevations at the dam, but the reservoir data was not collected due to sensor damage. Using the software GeoStudio Slope/W® Student Version, the dam is analyzed for slope stability. Okhissa Dam was analyzed for slope stability under conditions of steady state seepage and rapid drawdown. The results of steady state seepage analysis exceed the minimum design factor of safety of 1.5. The analysis for rapid drawdown is approximated due to insufficient knowledge of the behavior between the piezometric line and the upstream slope soils. The real time factor of safety readings show Okhissa Dam is stable

Development of Android Based Real Time Monitoring System for Fire-fighters

Fire-fighters are trained rescuers especially in extinguishing hazardous fires and saving lives from dangerous situations however they tend to put their lives at risk while on the job. Statistic shows the number of deaths of fire-fighters while on the job are still high up to this year and a higher percentage of rapid fire progress and exertion are dedicated to the cause of death of fire-fighters while on the job. Therefore, a real-time monitoring on the physiological state for fire-fighters is something crucial to be done. However, the Fire and Rescue Department of Malaysia practices the traditional communication method which is by communicating via walkie-talkie. The practice of real-time assessment should be carried out by Fire and Rescue Department of Malaysia in order to avoid having a fire-fighter’s live at risk. This could be achieved by using the ARMOR (Android Based Real Time Monitoring System) whereby it can transmit voice data and physiological data such as heart rate, respirator rate, peak acceleration and posture. Based on the research and critical analysis, an android platform have been found to be a suitable selection as it supports Bluetooth Wi-Fi and Radio Frequency, accessible from any android devices and it is user friendly. As a result, a real-time intelligent monitoring system was successfully developed on an android platform. The physiological data for heart rate, respiration rate, posture, and peak acceleration was successfully transmitted and monitored on an android device at real-time

DESIGN OF LABORATORY SCALE REAL-TIME MONITORING SYSTEM FOR UNDERGROUND MINING USING WIRELESS NETWORK

Underground mining is one of the mining systems that has a high potential risk of work accidents. One of the potential dangers is the emergence of gasses that can cause disruption of the respiratory system in humans. To minimize this risk, it is necessary to periodically monitor the gas that appears in the work area. This study aims to design a laboratory environmental monitoring system for underground mining using Arduino Uno as a controller that uses sensors of temperature, oxygen, carbon dioxide, and wind speed. Sensor data is sent wirelessly to the main monitoring system with point to point topology. The design of the software is carried out as a place to store data from the sensor which is then displayed in a monitoring information system in real time. From the results of system testing, sensor data is taken in a span of 1 second which is generated by a system with an accuracy rate of 99.9%. Overall, the system can be used properly to real monitor the environmental quality of underground mines

Real-time monitoring system for shelf life estimation of fruit and vegetables

The control of the main environmental factors that influence the quality of perishable products is one of the main challenges of the food industry. Temperature is the main factor affecting quality, but other factors like relative humidity and gas concentrations (mainly C2H4, O2 and CO2) also play an important role in maintaining the postharvest quality of horticultural products. For this reason, monitoring such environmental factors is a key procedure to assure quality throughout shelf life and evaluate losses. Therefore, in order to estimate the quality losses that a perishable product can suffer during storage and transportation, a real-time monitoring system has been developed. This system can be used in all post-harvest steps thanks to its Wi-Fi wireless communication architecture. Several laboratory trials were conducted, using lettuce as a model, to determine quality-rating scales during shelf life under different storage temperature conditions. As a result, a multiple non-linear regression (MNLR) model is proposed relating the temperature and the maximum shelf life. This proposed model would allow to predict the days the commodities will reduce their theoretical shelf-life when an improper temperature during storage or in-transit occurs. The system, developed as a sensor-based tool, has been tested during several land transportation trips around Europe.The authors are grateful to Fruca Marketing S.L. for providing the lettuce used in this research, and to Transportes Directos del Segura SL and Transportes Mesa SL for the logistic support. We also are grateful to Miriam Montoya Gómez for the translation services

Real Time Monitoring System on Solar Panel Orientation Control Using Visual Basic

Problems that often occur in the use of solar panels are the efficiency of solar panels and monitoring of solar panel generating systems. Monitoring of the output parameters of solar panels is very necessary to assess the performance and efficiency of a solar panel in real environmental conditions. Internet of Things (IoT) can make devices communicate with each other such as sending and receiving data. A monitoring system based on a wireless sensor network was created to make it easier to get direct and real time information on the output parameter data of the solar panels. The research objective is to create a monitoring system on a solar panel using Visual Basic and Blynk applications. This system is designed to determine the output parameters of the solar panel in the form of current, voltage, light intensity, and position which are processed directly and displayed in tables and graphs in Real Time conditions. The use of logger data in this monitoring system is very important. From the results of tests carried out on this monitoring system, the system is able to record and read the output parameters regarding the resulting current and voltage data as well as light intensity and the position of the solar panels. Information about measurement data from each sensor will be stored in the database and can be obtained directly through an excel spreadsheet
