An electrical system that fits. More availability and safety for the Merkenich Power Plant Reference – Electrical Solutions Instrumentation, Controls & Electrical SPPA-E3000 Generator to Grid encompasses the entire electrical system, from the generator to the grid, for parts of the Merkenich district heating plant. Compact switchgears are flexibly integrated and offer extra safety. The Result ■ High adaptability of the generator switchgear thanks to compact design and efficiency ■ Improved availability thanks to high-quality components and proven concepts, augmented by innovative technologies ■ Arising generator currents are handled safely and reliably The Plant As a local energy provider, the Merkenich district heating power plant supplies the Ford-Werke and its suppliers with process steam, as well as remote heating to the north of Cologne. The 50-year old plant belongs to the RheinEnergie AG. It comprises one lignite unit with fluidized bed firing and two further gas boilers with an electrical output of 100 MW. HB1 is designed for highest operating currents and mechanical stability - thus improves the safety for the plant itself as well as for the workforce. In addition, the electrical system in the mediumvoltage area and the new unit protection were integrated into the I&C system SPPA-T3000 by means of IEC 61850. This seamless integration improves operation and observation, enhances transparency and increases plant availability. Equipped with SPPA-E3000 Generator to Grid, the Merkenich district heating power plant is fit to face the future. The Task To ensure permanent operation, to improve the availability and economic viability of the plant as a whole, Merkenich was converted from a range-type to a unit-type power plant. Therefore an end-to-end solution was required, comprising of both the I&C and electrical system as well as capable of being integrated smoothly into the plant‘s existing structures. Our Solution The electrical solution SPPA-E3000 Generator to Grid offers the required comprehensiveness. The Siemens HB1 generator circuit breaker was deployed here for the first time in Germany. The electrical system, which was individually adapted and configured to the power plant’s needs, was assembled and commissioned on schedule at the construction site. Thanks to its minimal space requirement, the HB1 generator circuit breaker was positioned within the existing machine hall without any problems. “It was possible to obtain all the new components for our modernization from a single source. The new switchgear has a compact design – perfect for a smooth integration into our existing infrastructure.“ Gerhard Meyer, Referent Electrical Systems, RheinEnergie AG Answers for energy.
