Visualization and operation of photovoltaic plants with WinCC

WinCC (Windows Control Center) is a visualization system which runs on Microsoft Windows. It is used to monitor and control photovoltaic plants in which SINVERT inverters are installed.

WinCC provides all the functions required to visualize and operate PV plants, from the PV generator itself to the inverters and grid connection. It can also acquire data (e.g. energy yields) and store it on a long term basis, acquire, store and vi- sualize alarms and messages, and provide data interfaces to external systems.

WinCC can run on a Microsoft Windows PC that is connected to the Industrial Ethernet network of the PV plant. Remote access to the WinCC visualization system is also possible over the Internet if the WinCC WebNavigator software has been installed (see graphic on page 16).

SINVERT WinCC enables consistently scalable plant configura- tions – from small PV power plants up to the GW range.

In addition, our visualization system can be configured easily and efficiently. The use of a standardized PV library allows customer-specific adaptations to be carried out. WinCC is configured individually according to customer requirements and specific features of the plant.

The key features of WinCC are:

■A clearly designed user interface provides an instant overview of all key data of the managed plants, subplants and inverters, e.g. states, energy production, and income

■Graphical representation of the monitored data (see graphic on page 17)

■Graphics with configurable content for quick visual access to customized displays of received and/or calculated data, e.g. sorted according to day, month, year.

■Alarms and messages for quick and simple troubleshooting and for ensuring that remedial measures can be quickly taken to minimize loss of earnings

■Remote monitoring over the Internet with the WinCC/WebNavigator option

■Acquisition, long-term storage and display of current and historical data

■Export of archived data to Excel using the DataMonitor option

■Plant monitoring (e.g. detection and display of faults in the photovoltaic generator through section-by-section measurement of the whole plant)

■Safeguarding of yield and optimum protection by monitoring the insulation value

■Messaging services using email and text messaging with the WinCC/AlarmControlCenter option

■Fault messages can be specifically configured for customized operations management

■Establishment of as many as 128 user groups, each with up to 128 individual users, and assignment of different authorization levels to the users and/or user groups are possible

■Representation of monitored plants on a map
