EuroProt family
 
The protective, automatic and SCADA functions more and more integrate in frame of the system philosophy seen the most modern in the power system industry. In the up to date system, the same devices are used for all these functions. The EuroProt device family made by ELKO-PROTECTA performs these demands. This information sheet writes about the common features of EuroProt family. Own features of members of this family is written in separate description.

EuroProt system
 
All the EuroProt devices consists of more cooperating microprocessors based intelligences. They work together by the aid of an especial, system-independent inner communication architecture. This architecture makes it possible to be able to apply as an RTU ("bay level computer") of substation and/or hierarchical SCADA system. In the same time, the well proved protections and automatic devices are constantly present in the device. Matching to the SCADA system is carried out on such a way the bay level SCADA modules are built into the device, which modules communicate with the higher level of SCADA ("head computer"). These modules have therefore such a surface ("protocol") which the equipment of higher level is able to handle. The devices of the EuroProt family are matched now to the MAB system made by INFOWARE Corp. and the PROFIELD system made by PROLAN Co. Ltd. The system-independent architecture mentioned above makes, of course, possible to match the devices to any other system. Among others IEC 60870-5-103 standard communication protocol is available.
The further benefit of the EuroProt system is as follows. The devices may be interconnected together, over the SCADA connection, through optical fibre cable loop by the aid of two independent communication channel, and they may put under supervision of an independent protection engineer's workplace.
All the EuroProt devices can be completed with independent fault recorder module as well. These are matched into the storing and reading system of the protection engineer's workplace.
 
Main features of EuroProt system
 
  • Intelligences of multi-processor can cooperate together
  • Power sources of the device are commonly used by more intelligencies with software supervision
  • The bay level of SCADA can be integrated in the device
  • It has an inner architecture of bus organization
  • Unlimited modularty depending on functions
  • Freely programmable output contacts (digital software matrix)
  • Programmable logical equation system (PROTLOG)
  • Up to date self monitoring and continuous "ready to work" checking system
  • Advanced man machine connection with more versions (by own keyboard or by external computer)
  • Graphical LCD display possibility for primer connection diagram and for control
  • Back up protection with self feeding ( without external power) as an option
  • Well proved, tested protections and automatic devices with system authority
  • Independent fault recorder option (min. 50 s registration time)
  • High speed optical fibre cable data transmission surface to the SCADA system
  • Possibility of independent protection engineer data transmission
  • User friendly handling programs for WINDOWS NT/95
  • Y2K compatibility
The general architecture of an EuroProt device can be seen at the figure below:
 
 
Design
 

All the EuroProt device will be delivered in a unified form of new appearance. The devices is manufactured in an up to date device case designed to this aim, or in a rack to be built into a standard 19" cabinet. Three different horizontal sizes of cases are formed depending on the required functions, and the especial outfits makes possible to mount to a relay panel ( i. e. connections from before) or to flush mounting (connections from back). In case of especial ambient condition, the device can be ordered with enclosure protection class of IP65 as well. The device cases have a decorative front plate with folio keyboard which consists of handling and displaying means both traditional ones with pushbuttons and parametring with external computer. Graphical scheme on the front plate serves to display the condition of handling means.

A typical application of EuroProt system is demonstrated in the following figure:
 
 
This information sheet writes the general and common features of the EuroProt family, therefore it shoud be taken together with the description of the concrete device in to account.
