Human Machine Interface for a Photovoltai Electricity Station

This paper presents a Human Machine Interface (HMI) applied for a command and control system used for an existing 0.8 MW photovoltaic station, which has no automation system before, located in the Giroc Area, near Timisoara Romania. 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. The refurbishment of this power station imposed the existence of a friendly and easy to use HMI, based on the existing specific data bases which could provide more info, at the dispatcher level of the implemented SCADA system. This interface was conceived using Visual C and provides synoptic maps, time evolution graphs, alarm windows or event reports.
