SCADA System for Solar Backup Power System Automation

Abstract

This paper aims to design a PV farm with SCADA system (Supervisory Control and Data Acquisition) for cost-effective community solar backup power. The design is to be used in rural village in Lebanon where power is needed for irrigation systems and houses. This is a daytime PV system, with no batteries needed. The design provides optimized monitoring, logging, and control. ON-grid system has capacity 288.3 KWp and annual produced energy 516.75 MWH with performance ratio 84.32 %. Design a typical solar system for pump has 5 HP to provide daily demand water volume 45 (m3/day). ON-grid system can supply up to 50 deep well pumps with power rate 5 hp for every pump. The carbon dioxide reduction of the system is 481.61.3ton CO2/year. In order to evaluate the effectiveness of this solution in Lebanon, the design used a small rural village in south Lebanon to design and performance evaluation of a system with take into consideration the economic study and environmental evaluation.
