What is power output?
Power Output means the average rate of electric energy delivery during one Metering Interval, converted to an hourly rate of electric energy delivery, in kWh per hour, that is equal to the product of Metered Energy for one Metering Interval, in kWh per Metering Interval, times the number of Metering Intervals in a one- …
What is the net power output?
Gross output power is electricity generated at terminal of the generator. Net output power is net electricity transmitted from a power plant to grid, subtracting electricity used in the plant by auxiliaries such as fans, pumps, flue gas treatment systems, air conditioning, and lighting, so-called house power.
How is net power calculated?
Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W .
How do you calculate the power output of a motor?
By taking the voltage and multiplying it by the associated current, the power can be determined. A watt (W) is a unit of power defined as one Joule per second. For a DC source the calculation is simply the voltage times the current: W = V x A.
How do you calculate the power output of a gas turbine?
The net power output of a gas turbine (Wn) is equal to the turbine section work minus the power necessary for the compressor section. By numerous variable substitutions and equation rewrites, the gas turbine net power output can be expressed as: Wn = mcpT1[(ηT(T3 / T1)– ((rp (k − 1) / k) / ηC))((1– (1 / rp (k − 1) / k)))]
What is the mass rate and specific enthalpy of a turbine?
The above equation can be also expressed as: m is the mass rate and h is the specific enthalpy of the working fluid. The net power output of a gas turbine (Wn) is equal to the turbine section work minus the power necessary for the compressor section.
How do you calculate the Q-W of a wind turbine?
The first law of thermodynamics states Q-W=m* (hout – hin). Plug in h values you have on your state stable and solve for W knowing that Q=0 since the turbine is isentropic. You should get the answer 4000 ±10 KJ/s. This value is a standard for turbines of this size and mass flow.
What is the formula for turbine work per mass of airflow?
From the conservation of energy, the turbine work per mass of airflow (TW) is equal to the change in the specific enthalpy ht of the flow from the entrance to the exit of the turbine. The term “specific” means per mass of airflow. The enthalpy at the entrance and exit is related to the total temperature Tt at those station: TW = cp * (Tt4 – Tt5)
