SPPA-E3000 Excitation Systems & Startup
Frequency Converters is the modernization solution for power plants of all types and sizes, featuring absolute reliability and superb efficiency.
The Task
After 15 years in operation, long-serving equipment is often no longer up to the task, e.g. because
■ spare parts are in short supply
■ outages exceed an acceptable level or
■ grid requirements are increasing
Reliable and efficient continuous operation is essential to the availability of the power plant
Each project features design and configuration tailored to the specific power plant, timeoptimized installation/commissioning, and complete documentation thanks to best-in-class project management (VGB Quality Award). To guarantee the best possible solution to match each case, we first analyze the situation as it stands before making the modifications desired.
We identify which components need replacing, which technology is best suited, and how the new system can be easily integrated into the existing installations and can be connected to existing instrumentation and control systems.
Siemens has dedicated its long years of experience as a power plant engineer, constructor and operator to developing its innovative excitation equipment. Over 4000 units on line demonstrate their reliability and sturdiness.
Siemens excitation systems & start-up frequency converters adapt perfectly to requirements in your power plant.
Our Solution
SPPA-E3000 excitation systems are ideal for modernizing synchronous generators of any make or brand. Thanks to their cutting-edge technology, they can be used with generators of all sizes in hydro, steam and nuclear power plants and together with gas turbine units. In gas turbine units, excitation systems can be used in combination with a startup frequency converter. The turnkey solution includes all necessary components and services.
Its modular structure and use of proven industrial components help significantly to improve reliability and reduce maintenance costs.
