SUPERVISION

PLC programming and association with industrial supervisory control systems on Windows PCs (SCADA) allow us to offer ourselves as a partner for all advanced automation applications.

Through applications of this type, the operating parameters of complex machinery and plants can be controlled from a single operator station in a graphical environment with immediacy and simplicity.

The quantities that can typically be managed are:

  • Setting times and displacements
  • Complex operations
  • Special cycles
  • Diagnostics for alarms and scheduled maintenance with the possibility of remote control and assistance
  • Production and inventory reports
  • Calculation of product costs taking into account downtime and other variables.

VISION EISY

SUPERVISION SYSTEM – PHOTOVOLTAIC SYSTEMS UP TO 10 MW

  • Proprietary SCADA software developed by Ei Systems Energy
  • Industrial Field PC
  • Server in the Control Room with Hot Backup or Cloud server
  • Monitoring panel with DATALOGGERs in the field
  • Communication line between the DATALOGGERS and the field PC

OPERATING LOGIC OF THE VISION EISY SUPERVISION SYSTEM

The supervision software, through weather conditions, date and time, makes an estimate of the instantaneous power generated by the PV array. Every parameterizable period of time, the software performs verification between the power actually generated and the estimated power.

If the power generated falls within the range of 1% to 3% of the estimated power, no alerts (other than the production data) will be sent, otherwise an alarm signal will be issued that will allow the operators to take charge of the problem and give them additional specifics on the location of the fault, (string frame and string involved in the anomaly), and in this way they will be able to provide specific indications to the technicians who will intervene in the field.

The system is designed to adapt to all types of installations, from newer to older systems, thanks to software equipped with specific plug-ins that make the system versatile.

Should the plant capacity under consideration be greater than 10 MW, it will be sufficient to add software modules and another field PC.

INDUSTRIAL FIELD PC

The industrial field computer, through proprietary software, communicates with the field DATALOGGERS and acquires all daily, weekly and monthly data regarding the plant with up to 800 strings.

In fact, it deals with:

  • Acquiring generic plant data at two different points (panel temperature, ambient temperature, solar irradiance)
  • Reading the meters of energy produced
  • Data acquisition of each string
  • Checking plant integrity on MV and LV side with related remote commands
  • Inverter data acquisition via serial line in RS 485 or RS 422
  • Cabin temperature control and ventilation/heating system control

This pc is powered by UPS which ensures its operation in case of power failure for 24 hours, and is connected to the WEB through which it sends information to the servers.

INDUSTRIAL SERVER OR CLOUD SERVER

The server used for this system (industrial or Cloud) can handle information for 32,000 strings, with enough memory to store data for 5 years.

In the case of industrial server, the connection is made by fixed IP address to the individual PCs in the plants, and it is connected to the Internet network. In addition, there is another server connected in hot backup.

In case of Cloud server, the supervision software is WEB BASED.

The server allows simultaneous management and monitoring of multiple plants:

  • It performs real-time monitoring of the operation of all components of a photovoltaic plant
  • The server, through the supervisory SCADA software, allows the management and monitoring of several plants
  • Manages historical archives of multiple plants
  • Allows comparative analysis of production and yield data from different plants
  • Manages the financial flows generated by the plants

Manages maintenance history for technical and economic aspects
