Power Management and Control for a Photovoltaic Electricity Station

This paper presents a command and control solution applied for an existing photovoltaic station, which has no automation system. The solution proposed consists in a SCADA system used in order to control some parameters like rated active/reactive power, power factor, voltage waveform and values, current limits. This newly conceived SCADA system will be used for the refurbishment of the existing 0.8 MW photovoltaic station, located in the Giroc Area, near Timisoara Romania. It will be structured on 3 levels. Level 0 will be the connection with the process inverters, level 1 will consist in the communication area and level 2 is dedicated to the dispatcher area. All parameters will be in direct relation to the inverters.
