Excitation system, turbine generator set technical requirements

Technical requirements and system-wide excitation systems for turbine generator set technical requirements are mainly: excitation system inside the unit and an electrical  Circuit breaker , they can reliably stop excitation, and in the drying process to ensure the rotor winding over-voltage value is not over the long-term safe operation of the insulation  mcb circuit breaker conditions allowed values​​, so that drying deexcitation time as short as possible, in order to try to limit the scope of the accident; electric field breaker should be able to distant switching,  circuit breakers ; system failure can be self diagnostic alarm, easy maintenance. Demagnetization resistance parameter selection is often due excitation resistor can also be used as the rotor winding over-voltage protection.
