A Developed SCADA for Remote PV Systems

2011

Supervisory Control and Data Acquisition (SCADA) systems based on PLCs are very complex, lower reliability, and require developed electronic industry in order to produce sophisticated PLC's. Information Technology (IT) industry requires simpler, cheap, no restrictions on software or hardware SCADA systems. This paper presents a new generation of Remote Terminal Unit (RTU) for SCADA system based on microcontroller for customer side distribution automation system. We have a common trend of attempting to lower SCADA costs on RTU side. Our paper goals are to go to deep in lowering the cost of RTU unit, freeing the software so lowering system cost, and to expand the open source technology culture away from the restricted one of the large companies. A proposed microcontroller-based SCADA system with an open source software and graphical user interface is introduced in this paper. Our proposed system cost lowering efforts depending on the simple remote terminal unit (RTU), and an open source software. The system is modular where the main terminal unit (MTU) with a human machine interface (HMI) can access many RTUs that can plug and play. The proposed system is designed, implemented and gave excellent results in collecting data, transmitting, monitoring, and applying system control as well. One of the most appropriate applications for SCADA is the remote area photovoltaic standalone systems. The SCADA is used as monitoring, control and management system.

Low-Cost SCADA System Using Arduino and Reliance SCADA for a Stand-Alone Photovoltaic System

Journal of Solar Energy, 2018

SCADA (supervisory control and data acquisition) systems are currently employed in many applications, such as home automation, greenhouse automation, and hybrid power systems. Commercial SCADA systems are costly to set up and maintain; therefore those are not used for small renewable energy systems. This paper demonstrates applying Reliance SCADA and Arduino Uno on a small photovoltaic (PV) power system to monitor the PV current, voltage, and battery, as well as efficiency. The designed system uses low-cost sensors, an Arduino Uno microcontroller, and free Reliance SCADA software. The Arduino Uno microcontroller collects data from sensors and communicates with a computer through a USB cable. Uno has been programmed to transmit data to Reliance SCADA on PC. In addition, Modbus library has been uploaded on Arduino to allow communication between the Arduino and our SCADA system by using MODBUS RTU protocol. The results of the experiments demonstrate that SCADA works in real time and ca...

Low-cost SCADA platforms for a solar energy system

2017

Conventional energy has been used from ancient times. Coal, natural gas, oil, uranium, and firewood are example of conventional source. These sources are consider the main source of air pollution. So, it is desired to use clean energy sources such as solar power, wind turbine, and hydro-electric power. We need to monitor and control parameters of clean energy sources when they are working as a power source. In this research, few low-cost Supervisory Control and Data Acquisition (SCADA) systems have been designed for a small photovoltaic system to save data in a text file and show it on monitor screen as a number or graph. The proposed system is designed using four methods. The first method, is based on low cost sensors, Arduino Uno, and Raspberry pi. These components are connected together to send data to web server on the internet (www.ubidots.com). Second method, is based on three things: low cost sensors, Arduino Uno, and free Reliance SCADA software. In this method, the data is ...

DESIGN OF A SCADA SYSTEM FOR A SOLAR PHOTOVOLTAIC POWER PLANT

DESIGN OF A SCADA SYSTEM FOR A SOLAR PHOTOVOLTAIC POWER PLANT, 2023

This paper presents the design and implementation of a solar panel data monitoring system using a SCADA (Supervisory Control and Data Acquisition) system. The system is built via the Siemens S7-1200 Programmable Logic Controller (PLC) and programmed using TIA (Totally Integrated Automation) Portal V17 software. The system includes various sensors and instrumentation for monitoring solar panel performance, such as temperature sensors, current and voltage sensors, and irradiance sensors. The PLC collects data from these sensors and transmits it to the SCADA software, which displays real-time data on the graphical user interface (GUI). The system also includes features such as alarms and notifications for abnormal conditions, data logging for historical analysis, and remote access for monitoring and control from a central location. The system's reliability and efficiency are enhanced through the use of the S7-1200 PLC and TIA Portal V17 software, which provide advanced programming and automation capabilities. Therefore, this solar panel data monitoring system provides a comprehensive solution for monitoring and optimizing the performance of solar panel systems, helping to increase efficiency, reduce downtime, and improve overall system performance.

A Low-Cost, Open Source IoT-Based SCADA System Design, and Implementation for Photovoltaics

NECEC, 2019

Supervisory Control and Data Acquisition (SCADA) has largely been proprietary, pricey, and therefore uneconomical for smaller applications. With proprietary SCADA systems, there is also the problem of interoperability with the existing system components, and communication systems. In this paper, we present the design and implementation of a low-cost, open source SCADA system based on the Internet of Things SCADA architecture. The proposed SCADA system consists of current and voltage sensors for data collection, an ESP32 micro-controller (Remote Terminal Unit) for receiving and processing the sensor data, and ThingsBoard IoT Server (Master Terminal Unit) for historic data storage and human machine interactions. The ThingsBoard IoT Server is locally installed on a Raspberry Pi single-board computer. Message Queuing Telemetry Transport protocol is implemented for data transfer over a local Wi-Fi connection. The system design procedures, testing and the results are presented in the paper.

SCADA SYSTEM SIMULATION FOR A PHOTOVOLTAIC ROOFTOP SYSTEM

BALKAN JOURNAL OF APPLIED MATHEMATICS AND INFORMATICS, 2022

The main goal of this research work is to design and develop an application program for monitoring photovoltaic (PV) systems in real time. In this research, a SCADA (Supervisory Control and Data Acquisition) system in LabVIEW (Laboratory Virtual Instrument Engineering Workbench) was simulated for a solar rooftop system of a household with a total installed power of 3.92 kW. T he t heoretical foundations for SCADA system and PLC (Programmable Logic Controller) have been laid. The implemented LabVIEW program is an automated computer program that enters temperature, voltage, number of solar panels and radiation and gives performance parameters, power parameters, cost of the PV system, annual energy value, daily energy, generated solar energy, and curves for annual and daily energy generation. The system designed in this way enables control of the solar system and overview of the production from the system. Furthermore, this system can be connected to a microcontroller, Arduino, or PLC, which will collect data from sensors and transmit it to the system. Finally, a conceptual solution is proposed for the introduction of a battery system on the already proposed PV system and the introduction of a PLC to control the charging and discharging of the battery, as well as the transmission of electricity from and to the grid.
