FAQ

If electric vehicles included a generator they could charge the battery while moving. It seems the best choice to me.

WELL THEN ITIS CALLED A HYBRID BECASUE IT IS NOT RUNING OFF OF STORED ENERGY AND CHARGED SOMWEWHERE ELSE I HAVE WONDER THE SAME THING AS WELL BECAUSE THE GREAT BIG LOCOMOTIVES THAT PULL HUNDREDS OF FREIGHT CARS USE A DIESEL ENGINE TO RUN A MASSIVE GENERATOR THAT RUNS ELECTRIC MOTORS AT THE WHEELS, ITS MORE EFFECIENT AND THAT BEEN USED FOR YEAR,S ON TRAINS,

I am wondering did water go over these reactors, and if they did is that what caused the problems, and if not, what in fact really happened?Could the devastation have been worse if water washed over it?

the reactors are right on the shore, the tsunami was right there. and yes it did wash over the plants. that's what caused the backup power to fail ! plus several fuel tanks washed away and water got in almost everywhere, however the containment units remained sealed, at least until the hydrogen steam pressure cracked them ! now the NRC reports there is radiation at deadly levels in the immediate area.japan is downplaying the crisis. and due to unconfirmed plutonium pollution, the area may be uninhabitable for 30,000 years or more ?

I have diesel generator and when I loaded it up to 400 KW trip due to low ferquncy in which its total load 905 KW after I check up , I think that because fuel is not increase to feed injuction pump so that I want to know how actuator working ?

By the revolutions of the generator, or the (presuming AC output) frequency of the power generated. If the frequency is low, the revolutions are low. If the revolutions drop off when load is added, or frequency falls, you have a problem. somewhere.

hiam in the process of purchasing a flat.under the electrical specifications, the builder has specifid the following. please explain me what does it mean by3 phase power supply with automatic change over switch and what does it mean by RMU Transformer with Advanced Features

This electrical specification describes some aspects of the electrical distribution system for a block of flats (apartment building in USA terms). A 3 phase power supply is 3 live wires and a neutral with 400 volts or so between any two live wires and 230 volts or so between any live wire and the neutral. Each flat would be connected to one live wire and neutral. A change over switch is a switch that can switch the load from one power source to another. It could switch between two mains connections from the power company or it could switch between the power company mains and a standby diesel generator set. An RMU transformer is a ring main unit transformer. The transformer would be the step down or substation transformer from the transmission line voltage to the 400 volt level. There would probably be one transformer for all of the flats, possibly two if there are two mains connections from the power company. The RMU designation indicates that the transformer includes additional components such as the change over switch and main circuit breaker as a single piece of equipment. Advanced features might include such things as transformer temperature monitoring, load monitoring, and remote indication provisions. Unless the features are enumerated, it isn't a particularly useful description. It may or may not include features in addition to the minimum required by government regulations. If you are purchasing only an individual flat, this might offer some assurance that the electrical system is modern and reliable, but it is a very poor description to offer prospective purchasers of individual flats.

I have a 1992 Toyota Tercel that sits in my yard. It ran at one time, but has been driven so little that it now no longer starts. Had this problem one time before and paid someone to fix it. They replace the fuel pump to get it started again. Other issues are lost title, back left tire seems locked, and busted windshield.I hate to just trash this car and wonder how difficult would it be to turn the motor into a backup power generator for my house? Is it feasible? One of our sister companies at work has a diesel engine that acts as a backup power for their computer room, so I wondered if I could possible do the same for my home.Any suggestions?

Yes just get your engine running and buy a giant alternator put it on your car. remove all other things from the belt that are not necessary to the engines functions. then call your electric company and tell them that you are trying to put a DC current into power your house. The power company (should not sure) provide the DC AC converter. Plus I know its true with solar panels, but if when you have your generator on, and your house is not using as much energy as its receiving your power meter will actually run backwards for feeding the grid. Which will might help with that cost of gas.

Having a basic background in electric and family moving into a remote prefab home with no electric, water, or gas, I decided to help. House and work shed electric requirements are simple, totaling a possible 5kwh at a given time to the shed, and 7kwh to the home. Obviously the home will have constant electric requirements (fridge, fans, etc). I cannot imagine it is economical nor efficient to run a diesel generator 24/7 for energy production as needed. Here are my questions:1. Should I use a stand-alone or emergency backup generator.2. Should I go with the conventional wisdom of choosing a generator that operates at 80% capacity for 1005 of my needs. IE: I need exactly 12kw maximum, so a ~14kwh generator.3. Solar panels have storage batteries. Can I use 12v or 18v, or an industry specific battery to only operate the generator for several hours a day for storgae of power? I know this is incredibly inefficient, any alternatives?Any help is greatly appreciated. Just need to be pointed in the right direction.

I think a stand alone gennie would be ok

I heard about the diesel electric concept from a friend and he didn't have a lot of details, but from what he knew it sounded really interesting. I was wondering if someone could give me some details on to what this new technology really is, and how it works. Thanks!

Can u plz help me to solve following problems:1.After an AC generator has been paralleled explain how the following are achieved for the incoming generator(i)Correct kW load sharing(ii)Correct load current when the generator has a different power factor to the other generators2. the cumulative damage that may be caused when the alternators are incorrectly synchronized3.For alternators operating in parallel the consequences of:(i)reduced torque from the prime mover of one machine(ii)reduced excitation on one machine

1. (i). Each engine should carry the SAME LOAD PERCENTAGE-wise, eg. 80%, to minimize the load change burden on the rest. (Smaller engines may run at full load, since their contribution may go unnoticed.) Since the overall kW bus load is constant, each generator will pickup a percentage of it, by controlling the torque on each prime mover. If it is a steam turbine, by throttling steam flow. If it is a diesel engine, by throttling fuel, and so. (ii). Each alternator should be adjusted to carry the SAME POWER FACTOR, by adjusting excitation accordingly, eg, .85, to avoid stability issues. Running alternators at leading power factors may turn the system unstable and force loss of synchronism 2. Considerable mechanical damage will be caused by incorrect synchronization to windings, shaft and keyways. 3. (i) reducing torque on one a prime mover is done when preparing to take it out of service. This has to be done gradually, so that other machines can pickup the load slowly. When close to unloaded, the generator can be taken off the grid. Power should never be reduced to the point of allowing the generator to be motored, i.e., reverse power flow, which can cause unpredictable damage to the turbine and system instability. (ii) reduced excitation is a very dangerous condition which will cause the power factor to turn leading, i.e., capacitive, weakening the synchronizing torque with possible loss of synchronism and forcing the bus voltage up. .
