Excitation systems ABB has been supplying excitation systems for more than 90 years. Our UNITROL 6000 static excitation systems and automatic voltage regulators have set the benchmark for functionality, reliability and connectivity at hydropower plants all over the world. The hardware and software components are fully integrated with ABBs plant automation system. The controllers are based on ABBs AC 800PEC family of highperformance processors, which combine the high-speed control requirements of power electronics applications with low-speed process control tasks usually carried out by a separate PLC. Standard UNITROL 6000 software includes all the regulation, protection and monitoring functions necessary for the secure operation of the excitation systems, and is customizable to meet specic requirements.

Static Frequency Converter and AC Excitation Applications A single static frequency converter (SFC), based on ABBs advanced power semiconductors, can be used to start several generator/motors, one after the other. The same SFC can also be applied for purging and slow turning during cooling. In pump storage hydropower plants this indispensable system ensures reliable start up and high availability of the turbine in pumping mode, lower investment costs compared to mechanical solutions, small footprint, easy maintenance requirements and limited wear and tear. The introduction of advanced Voltage Source Inverter (VSI) technology in AC excitation systems for Doubly-fed Asynchronuos Machines (DASM) in pump storage hydropower plants has been a major breakthrough in the application of variable speed units in pump storage hydropower plants. Thanks to the IGCT (VSI) technology used in ABBs AC excitation systems it was possible to reduce the costs and at the same time increase the performance of the variable speed technology. The exibility given by this technology in respect of response to uctuating grid conditions improves the overall economic performance of the power plant considerably. Last but not least the application of frequency converters (FC) in connection with Permanent Magnet Generators (PMG) opens up new opportunities in the eld of small to mini hydropower plants. The FC handles the control and protection of the generator without the need for separate protection, synchronization, excitation and circuit breaker equipment. Moreover ractive power control and compensation can be done eventhough the turbine is not running. With its cost saving potential this solution may turn projects, considered unpro table with conventional technology, into pro table ones.
