Efficient and future-proof solutions for drive systems Service Solutions Instrumentation, Controls & Electrical Performance Enhancements Modernization of frequency converters in power plants replaces obsolete frequency converters with tailored, high-quality components, thus increasing availability and reliability. The Solution offers significant savings potential and provides a whole range of new convenient features. Your Benefits ■ Greater reliability through fewer individual components, more efficient power electronics ■ Reduced costs through energy savings from conversion of variablespeed gear units and from replacement of reactor elements ■ Higher availability of modernized frequency converters through longterm supply of spare parts The Task Even though the power plant is otherwise in good condition, obsolete converter technology for electric drives becomes a risk factor for operation of the plant, for example, because it is no longer supported by the manufacturer. As frequency converters age, the risk grows that the manufacturer will no longer provide full sup-port. In the event of a fault, it may be hard to find suitable spare parts and personnel trained in the old technology. The remedy is replacement with modern drive systems. Our Solution Siemens replaces obsolete converter systems with the latest technology – regardless of the original manufacturer, drive system concept, or application. Modern frequency converters not only boost plant efficiency and availability, but also upgrade your plant with state-of-the-art features – especially improved self-diagnostics, simple parameterization, and integration into the unit I&C, greater resistance to harmonics and system disturbances, and reduced reactions on the system due to the converter itself. The portfolio is flexible and scalable from the smallest to the largest application – for both the low- and medium-voltage levels. Even high mechanical and hydraulic equipment that consume high amounts of energy for speed setting of pumps and blowers can be replaced by economical drive systems with frequency converters. Thus payback times can be as short as one year. Siemens can not only provide complete and expert advice, we can also process the entire upgrade including all necessary steps. We offer frequency converters in all performance classes, and can also supply any necessary matching drive motors and converter transformers. Because our concept is based on maximum use of standardized components, you can count on our system support for a long time. And of course, after modernization, spare parts and support will again be available for reliable operation of your plant for years to come. Modern frequency converters can be perfectly integrated into the I&C of your plant. Answers for energy.
