Description of implementation:
The company Vychodoceska plynarenska is a gas distribution company in east-bohemian region. The company decided to innovate its main SCADA/HMI system in 1998. After thorough evaluation of several SCADA systems, the gas distribution company had chosen Reliance. The aim of a new system was to visualize all interchange super high-pressure regulation stations and high-pressure regulation stations.
The approach of the company has been very active since the beginning. People from the gas distribution company wanted to create and maintain the visualization by themselves, so after creating the basic project for several first regulation stations, people were well trained to be able to maintain and expand the system independently.
Several tens of regulation stations were modernized and connected to the system every year. In 2004 all gas regulation stations were finally connected to the visualization. The system now consists of more than 400 regulation stations is communicating with the main control room 24 hours a day.
