How many mega volt ampere are there in a 1 mega watt generator?
In a 1 megawatt (MW) generator, the unit of power is given in terms of megawatts, which represents one million watts. A megavolt-ampere (MVA) is a unit of apparent power equal to one million volt-amperes. Therefore, in a 1 MW generator, the apparent power rating would also be 1 MVA, as the apparent power rating is typically equal to the real power rating in a generator with a power factor of 1.
What does mva stand for in the turbo generator field?
There are two concerns here regarding loading on transformers of this size. First is the difference between MVA and MW. MW is just real power -- watts. MVA is total power which includes real power (MW) and reactive power (MVAR).--- http://en.allexperts.com/q/Electric-Power-Utilities-2405/operation-limit-oof-power.htm
What does mva mean in electrical terms?
MVA is the apparent power. MVA=( MW+ MVAr)1/2
A transmission line has 30 megawatts and 40 megavars what is the megavolt amps load on the line?
By definition, MVA is equivalent to the vector sum of MW and MVAR: MVA^2 = MW^2 + MVAR^2 = 2500 MVA = 50
What are the top ten largest earth dams?
The Three Gorges Dam project in Hubei, China, is the world's largest hydroelectric generating system. It includes 2 generating stations. They are the Three Gorges Dam (22,500 MW when completed) and Gezhouba Dam (3,115MW). The total generating capacity of this complex is currently at 21,515 MW. The whole project is planned to be completed in 2011. The total generating capacity will be 25,615 MW by then. The other nine dams are as under. Itaipu, Brazil-Paraguay, 14000 MW Capacity; Guri,Venezuela, 10200 MW; Tucuruí,Brazil, 8370 MW; Grand Coulee, United States, 6809 MW; Sayano Shushenskaya, Russia, 6400 MW; Krasnoyarskaya, Russia, 6000 MW; Robert-Bourassa, Canada,5616 MW; Churchill Falls, Canada,5429 MW; AND Bratskaya, Russia, 4500 MW;
How do you convert mw to mva?
You would have to know the Power Factor, normally designated PF. MVA x PF = MW. If the PF is unity then MVA = MW. A PF of UNITY suggest the load is purely resistive with neither capacitive nor inductive components in the load or source. Of course this can mean such components have been balanced artificially.
A transmission line has 30 mw and 40 mvar flowing what is the mva flow on the circuit?
MVA= square root of (MW2 + MVAR2 )
How much does it cost to build a dam?
A large hydropower dam on average costs 1800 million in 2010 USD with an average installed capacity of 630 MW.
Is Tekeze Dam in Ethiopia the largest dam in Africa?
No, it's the second largest to Vaal Dam. Gele Gebe 184 MW Gele Gebe II 420 MW ,tekese is 300 MW Gelele Gebe III is 1870 MW 65 % completed Grand millennium is 5250mw 10 % completed . ethopia have 2094 have electricity capacity so for not including Gele Gebe III and Grand Millennium
How is a 100 MVA transformer cooled?
Large transformers are filled with oil which circulates to a radiator to get rid of excess heat. A 100 MVA transformer should waste about 1 MW of power on full load, 0.5 MW on no load.
How do you calculate MVAR with mw and mva?
mw/mva=power factor reactive power(Q)=I2XL or E2/XL where XL= REACTANCE apparent power = square root of (MW2 + MVAR2 )
How many kWh will a 2 MW generator produce?
A 2-MW generator will be producing 2000 kW (2 MW) during 1 hour, so 2000 kWh in 1 hour. So, 24 x's 2000 is 48,000 kWh per day. This is assuming it is continuously operating at 100% capacity, 2 MW. Adam Fuller
