Supervision and Monitoring of Photovoltaic Systems Using Siemens PLC and HMI

Abstract

Automation is the top priority in modern industries, the debate on this phenomenon is always controversial as the machine tends to replace man in several tasks, and he unfortunately cannot perform the tasks that the machine does in several fields. The supervision and monitoring of the industrial systems are two very important fields in industrial automation. For ensuring the reliability and stability of PV system operation, it is indispensable to install supervision and monitoring systems. The work in this paper presents a simple platform for supervision and control in real-time of pumping system parameters (current, voltage, irradiance, temperature and flow) based on programmable logic controller (PLC) and human-machine interface (HMI) of Siemens tools.
