SCADA
Basic purpose of the system:
- Increase of the operation reliability of GDN and the operation control of the GDN items is expressed in the supply of natural gas consumers, whose technological parameters meet the legal requirements and by describing of the full equipment along the gas transmission network.
- Increase of safety operation and the decrease of emergency hazards - with the increase of the GDN length and the number of safety providing devices it is necessary to improve the monitoring and control of the GDN processes.
- Increase of efficiency is characterized with decrease of the operation expenses, optimization of the activities in cases of emergencies, as well as other factors, accompanying the GDN service.
- Improvement of operation in processing and storage of clients’ data.
-
Provision of managing information through synthesis and analysis of the stored data.
Facilitating of operational accounting service is in compliance with the latest legal regulations....
