Your company is considering the installation of a 2 MW wind turbine with a rotor diameter of 80 m in a location with average wind v = 10 m/s. The turbine has a cut-in velocity of 5 m/s and a cut-out velocity of 25 m/s. The capacity factor is 0.45. The installed cost of the turbine is $3,500,000. Operating expenses are $225,000 per year. The system has a power coefficient (electric power generated divided by wind power) of 0.45.
Load flow analysis
Load flow analysis is a study or numerical calculation of the power flow of power in steady-state conditions in any electrical system. It is used to determine the flow of power (real and reactive), voltage, or current in a system under any load conditions.
Nodal Matrix
The nodal matrix or simply known as admittance matrix, generally in engineering term it is called Y Matrix or Y bus, since it involve matrices so it is also referred as a n into n order matrix that represents a power system with n number of buses. It shows the buses' nodal admittance in a power system. The Y matrix is rather sparse in actual systems with thousands of buses. In the power system the transmission cables connect each bus to only a few other buses. Also the important data that one needs for have a power flow study is the Y Matrix.
Types of Buses
A bus is a type of system of communication that transfers data between the components inside a computer or between two or more computers. With multiple hardware connections, the earlier buses were parallel electrical wires but the term "bus" is now used for any type of physical arrangement which provides the same type of logical functions similar to the parallel electrical bus. Both parallel and bit connections are used by modern buses. They can be wired either electrical parallel or daisy chain topology or are connected by hubs which are switched same as in the case of Universal Serial Bus or USB.
plz solve only part 2
Your company is considering the installation of a 2 MW wind turbine with a rotor diameter of 80 m in a location with average wind v = 10 m/s. The turbine has a cut-in velocity of 5 m/s and a cut-out velocity of 25 m/s. The capacity factor is 0.45. The installed cost of the turbine is $3,500,000. Operating expenses are $225,000 per year. The system has a power coefficient (electric power generated divided by wind power) of 0.45.
part 1) What price would you have to get for the electricity you produce to obtain a 10% return on the plant investment assuming a project lifetime of 20 years? Use the tables for the cumulative wind power distribution in the notes on wind probability to answer this question. Assume an air density of 1.225 kg/m3.
The answer is equal to 0.0815 dollar
part2) How would your answer to problem one change for each of the following modifications to the data in that problem? (Consider each change independently, not as a cumulative series of changes.)
- The average velocity is lowered to 8.5 m/s.
- The rotor diameter is increased to 90 m.
