6 FAQs about [Generator excitation end inlet air temperature]

What type of excitation system is a generator?

Exciter systems can be rotating or static. Rotating includes brushless and brushed types and static includes compound sources and potential sources. A generator has a prime mover like a turbine or diesel generator. The excitation system creates the electromagnetic field in the rotor.

How does a 150 MW air-cooled turbine generator ventilation system work?

According to the practical structure of the ventilation system of the 150 MW air-cooled turbine generator, as shown in Fig. 2, a global flow resistance network is set up to determine the flows and pressures of the inlet and the outlet of the air cooling ventilation system.

How to investigate the heat transfer law of a turbine generator?

To investigate the heat transfer law of the studied turbine generator, it is necessary to analyze the temperature distributions, expecially the heat transfer of the air-gap. 1. Temperature distribution in the axial cross section of the turbine generator

How does a brushless excitation generator work?

It demonstrates that the brushless excitation is realised and the output voltage is regulated by the stator excitation current. Brushless excitation generators exhibit several key features, such as high reliability, easy maintenance and so on [1 - 5].

How to estimate excitation system parameters?

Estimation of excitation system parameters can be performed in on-line or off-line mode. Since there are a lot of nonlinear parameters, ofﬂine tests can be more effective because, in ofﬂine mode, it is possible to excite most of the nonlinear zones .

What are the outputs of a generator?

Outputs include annunciation, alarms, meters, and a full range of data for the distributed control system. A power bus is required to feed the exciter current to each end of the rotor coil. Field breakers are used to protect both the AC and DC sides of the generator. Power rectifiers convert AC power to DC power.
