Description & Project Overview
The converter plant, which has been completely out of operation since December 21, 2015, is to be modernized as part of a comprehensive retrofit and upgraded for future operation. For this purpose, it is planned to completely rebuild the converter E1. The converter E2 is to be partially overhauled and essential parts of the system renewed.
At the same time, the associated electrical systems, switchgear, control and supply equipment as well as the necessary auxiliary units for both converters are to be renewed or adapted to future operational requirements. As part of the modernization, the refrigeration systems will also be replaced. A new cold water system is to be built to dissipate the heat loads occurring in the technical operating rooms and to maintain the permissible room temperatures.
Separate direct evaporator systems are also provided for selected areas. In addition, the work and recreation rooms of the operating staff should be air-conditioned in accordance with the respective indoor climate requirements. A redundant cooling supply is required for the technical rooms.
The cold water system must therefore be designed in such a way that if one refrigeration system fails or is switched off due to a fault, the remaining system can provide the cooling capacity required for safe system operation. The hydraulic integration as well as the control and regulation technology must be carried out appropriately so that the cooling supply is maintained even in the event of a malfunction and unacceptable heating of the technical equipment is avoided. The aim of the planned measures is to technically upgrade the converter plant and to create the conditions for safe, reliable and permanently available operation.
