Case study on Redundant system Building


Huge energy management system building

 Tiszai Vegyi Kombinat (in short TVK- Tisza Chemical Group Ltd Co) is a Hungarian manufacturer of olefins and polyolefin such as polyethylene and polypropylene. Feedstock is supplied by MOL of which TVK is a subsidiary and which also processes a major portion of resulting by-products from the olefins plant.

The company’s legal predecessor, Tiszavidéki Vegyi Kombinát, was built in the 1950s, involving the excavation of 700,000 m3 of soil and the installation of one million m3 of material.

The Petrochemical Development Project, worth EUR 430 million, implemented in record time even by international standards, TVK has successfully expanded its capacity in three key areas. The production process includes two major stages: producing monomers and polymerisation.

Completion of the petrochemical expansion project has provided economies of scale that enables TVK to retain a leading position in central and Eastern Europe and to strengthen its market presence in the European Union. Ethylene and high density polyethylene (HDPE) production capacity has been doubled while polypropylene capacity has also been expanded.

Tisza Chemical Group Ltd Co also supplies feedstock to several companies engaged in plastic processing operations. The Company's products are supplied to the domestic market and exported to Central and Eastern Europe.

TVK used AVReporter Energy Management Software to create the most suitable Energy Management System.


The following areas were also addressed with the requirements according:


SQL Server Datacentre Maintenance:

  • frequency of performing the maintenance duty is 3 months
  • control of capacity
  • index examination
  • elevation of index fragmentation
  • analysis of logged faults and their correction
  • the checking of the saving security
  • checking the working order of the drivers
  • load testing
  • checking of the data deletion
  • archiving of the system logs and event log  

Database back-up:

  • transaction log hourly back-up
  • differential back-up every other day
  • full back up every week  


Key elements for system planning and implementation:


When building such a huge or similarly complex energy management system special attention should be paid to the following system characteristics:

  • the HDD performance and the number of IO expressions dictate high attention to detail when logging huge amount of data
  • when handling a huge database it is advised to handle the operation system, the SQL database and the SQL Logging data  in a separate RAID
  • also it is highly important when building such a huge and complex system to choose a hard drive with the right speed. Slow hard drives it is not possible to complete virtual calculations between the SQL data.
  • when using huge quantities of virtual meters take advantage of the Realtime Virtual Meters instead of the Advanced Virtual Device Manager, as this one runs the calculations between the data stored in the SQL data base, which means more demanding IO expressions and strain on the SQL server. The Realtime Virtual Meter runs the expressions in the memory, so needs a lot less capacity.
  • when operating high numbers of pre-scheduled reports, the report generation should not be all done at once in avoidance of the possible overloading of the SQL server.
  • the old and not any more necessary data’s deletion should be done regularly in smaller batches to keep the performance of the SQL server steady. Also the deletion for huge data quantity can block the SQL server’s logging.
