Electric Power Plant Design


Quiz Questions

1.This course provides engineering data and criteria for designing electric power plants where the size and characteristics of the electric power load and the economics of the particular facility justify on site generation. Maximum size of the plant considered in this course is 30,000 KW.
True
False
2. Which one of the following information is needed for the plant design:
Forecast of annual diversified peak load to be served by the project
Typical seasonal and daily load curves
If the plant is to operate interconnected with the local utility company, the designer would need information such as capacity, rates, metering, and interface switchgear requirements.
If the plant is to operate in parallel with an existing generator on the facility
All of the above
3.The type, availability, and cost of fuel will be determined in the early stages of design; taking into consideration regulatory requirements that may affect fuel and fuel characteristic of the plant.
True
False
4.To meet various environmental regulations, it is often necessary to utilize design features that will greatly increase the cost of the power plant without increasing its efficiency. For example, the cost of the pollution control equipment that will be required for each site under consideration is one such item which must be carefully evaluated.
True
False
5.Some of the physical characteristic of the plant site would be:


– Availability of the usable land for the plant
– Fuel handling facility
– Soil information
– Site drainage
– Wind data
– Seismic zone
– Ingress and egress

True
False
6.In steam power plant practice, cogeneration normally describes an arrangement whereby high pressure steam is passed through a turbine prime mover to produce electrical power, and hence from the turbine exhaust (or extraction) opening to a lower pressure steam (or heat) distribution system for general heating, refrigeration, or process use.
True
False
7.Terminal voltage ratings for power plant generators depend on the size of the generators and their application. Generally, the larger the generator, the higher the voltage.
True
False
8.In ventilation of indoor air inside the plant, supply fans will be selected so that the indoor temperature does not rise more than 15 degrees Fahrenheit above the ambient outdoor air design temperature, and to maintain a light positive inside pressure with all the exhaust fans operating at maximum speed.
True
False
9.Power plant piping systems, designed to transfer a variety of fluids (steam, water, compressed air, fuel oil, lube oil, natural gas) at pressures ranging from full vacuum to thousands of psi, will be engineered for structural integrity and economy of fluid system construction and operation.
True
False
10.Gas turbine generators typically have significantly higher heat rates than steam turbine or diesel power plants. However, their higher fuel costs quickly outweigh their initial advantages in most applications.
True
False
11.Each gas turbine manufacturer has his own specification on fuel acceptable for his turbine. The high grade liquid fuels such as Diesel No1. or 2 and JP-4 or JP-5 will likely be acceptable to all manufacturers.
True
False
12.Diesel engines have higher thermal efficiencies than other commercial prime movers of comparable size. Diesel engine-generators are applicable to electric loads. From about 10 to 5000 kilowatts.
True
False
13.Diesel engine -driven electric generator sets are divided into three general categories based on application as follows:

– Class A: generator sets for stationary power plants generating prime power continuously at full nameplate kw rating as the sole source of electric power
– Class B: generator sets for stationary power plants generating power on a standby basis for extended periods of time where months of continuous operation at full nameplate kw rating are anticipated.
– Class C: generator sets for stationary power plants generating power on an emergency basis for short periods of time at full nameplate kw rating where days of continuous operation are anticipated.

True
False
14.In general combined cycle power plant is the combination of gas turbine generator (Brayton cycle) with turbine exhaust waste heat boiler and steam turbine generator (Rankin cycle) for the production of electric power. If the steam from the waste heat boiler is used for process or space heating, the term "co-generation" is the more correct terminology (simultaneous production of electric and heat energy)
True
False
15.Figure 8-1 is a :
Combined cycle diagram
Rankin cycle diagram
Brayton cycle diagram
None of the above.
