Modernization of electrical energy measuring systems at limit points of ZEB SA was made by the company APS S.A. in consortium with the company ZWSE Białystok PP.
Out of nine points subject to modernization, APS S.A. it performed works on four of them:
- station 110/15kV Elektrociepłownia Białystok,
- station 220/110kV Ostrołęka,
- station 220/110kV Ełk 1,
- station 400/110kV Narew.
The scope of work performed by APS S.A. included:
- delivery of materials and equipment,
- prefabrication of measuring cabinets,
- installation of measuring cabinets on stations with elevation of GPRS data transmission and GPS receiver outside the building,
- connection of measuring cabinet to current and voltage circuit converters and supply circuits in switching stations for own needs and guaranteed voltage switching stations
- participation in the launch systems.
In the modernized measurement, primary and backup systems were used ZMD402 CT LANDIS&GYR meters with time synchronization. Data from the meters were introduced to the existing eSPIM system in such a way that the transmission from the basic system is made through the GPRS system and the backup data are entered in a built-in closet measuring hub DATAWIN 2002, and then sent to a system based on GSM or communication equipment available at the station (fiber, cable connection).
The applied solution provides access to measurement data at different sites in different standards of communication, their reliable readout and verification the measurement data.
Further works of APS S.A. consist in execution of telemechanics on stations HV/MV RPZ Czyżew, Sokółka and Olecko.
Modernization of the station 110/15kV RPZ Czyżew ofwith a 32 field 15kV switchgear and 6 field 110kV switchgear, implemented under a contract with PGE Dystrybucja Białystok Sp. z o.o., and equipped it with a distributed system of object controllers for this switching station and own purposes of the station.
