Korea District Heating Corporation and ABB co-operate over years for a happy energy world, with long experience of control systems from different generations.
Heating Seoul with environmental responsibility
KDHC, Korea District Heating Corporation, is a state owned company that was established in 1985. The mission is to create “a happy energy world”, by providing people with comfortable and convenient living conditions through energy conservation and environmental improvement.
KDHC was founded by the Korean government, as a direct answer to the United Nations Framework Convention on Climate Change. The company takes its environmental responsibility deeply serious and is most concerned to operate well controlled, reliable, and highly energy-efficient processes.
The second largest plant of KDHC is Gangnam in Seoul, supplying 134 000 households. The demand is ever increasing.
When the existing Asea Master control system was growing close to its capacity limits, KDHC had worries that unexpected malfunction would happen during normal operation. It was especially important to replace the conventional and somewhat old MasterView operator stations with state-of-the-art operator workstations.
Backward compatibility and investment protection
To maintain reliable function and also to secure higher performance at cheaper price in the future, ABB recommended upgrading step by step as the best solution.
One of the most important factors for KDHC was to protect the existing investment by the reuse of controllers, application software and I/O units. The unique backward compatibility that ABB provides, whenever new releases are made, is highly appreciated by KDHC. In a later upgrade the oldest controllers, MP 280/1, can be replaced by AC 450 or AC 800M.
