Power station generator main shaft air supply chamber

6 Frequently Asked Questions about “Power station generator main shaft air supply chamber”

What are the station service power requirements for combustion engine generating plants?

Station service power requirements for combustion turbine and internal combustion engine generating plants are such that 208 or 480 volts will be used. 1.1.4 DISTRIBUTION SYSTEM. The primary distribution system with central in-house generation should be selected in accordance with the owner's requirements. 1.2.1 GENERAL.

What is included in a dedicated compartment of a generator?

The dedicated compartments also contain the generator surge protection equipment (see Chapter 3, “Generators”). Specified accuracy classes for instrument transformers for either type of procurement should be coordinated with the requirements of the control, protective relaying, and metering systems.

What type of generator is used for gas turbine service?

Generators for gas turbine service are revolving field, nonsalient or salient pole, self-ventilated, open drip-proof type, sometimes connected through a gear reducer, depending on manufacturer's gas turbine design speed, to the gas turbine power takeoff shaft.

What is a terminal voltage rating for a power plant generator?

Terminal voltage ratings for power plant generators depend on the size of the generators and their application. Generally, the larger the generator, the higher is the voltage. Generators for a power plant serving an installation will be in the range from 4160 volts to 13.8 kV to suit the size of the unit and primary distribution system voltage.

What are the different types of station service power systems?

Two types of station service power systems are generally in use in steam electric plants and are discussed herein. They are designated as a common bus system and a unit system. The distinction is based on the relationship between the generating unit and the auxiliary transformer supplying power for its auxiliary equipment.

Should power cables be a limiting factor on turbine generator output?

In no event should the current carrying capacity of the power cables emanating from the generator be a limiting factor on turbine generator output. As a rule of thumb, the cable current carrying capacity will be at least 1.25 times the current associated with kVA capacity of the generator (not the kW rating of the turbine).
