The system is suited to visualize the parameters of Satec devices, used for accurate  measuring of electicity phases, power, power factor etc. This is accomplished by a link with Unitronics – V540 controllers and the modules they need. A structural scheme of the system and the way the data is exchanged between the devices is shown:

Fig.1

The data which is sent to the computer is archivated in an application,with an option to do a search with a query. The basic data is shaped into visualization data type for continuous observation with the help of two applications.

The first programme is – OPC server for converting the data, received from the local network.   

The second programme Scada is for visualizing the power substation and the installed in them devices – Satec, Switches/Circuit-breakers and the links between them.In every power substation is isnstalled a Unitronics – V530 controller.

Fig.3

The Satec devices are visualized as a table, with which two basic parameters are watched:

Ø      Full power (kVA);

Ø      Active power (kW);

Ø      Power factor – Cos φ.

There are alarm messages that will be shown in an additional window at the moment the failure signal is received.
