Design of a SCADA System Based on Open-Source Tools

This paper presents the development of a supervisory system that uses Internet of Things (IoT) devices that can be implemented in any type of power plant. By applying the new concept of Internet of Things, it is possible to create an information sharing environment that simplifies and increases the effectiveness of supervisory and control systems. The goal of this paper is to present a supervisory system based on open-source tools for a photovoltaic power plant, using IoT devices and adapting non-IoT devices to the new generation of current automation (the trend of incorporating IoT concepts to processes). This new supervisory system improves the current supervisory system adding new features and increasing acquisition time. Besides the development of the new supervisory system, this paper also provides a comparison between the current supervisory system and the new supervisory system in order to highlight the main benefits of the latter.
