The SPM-D11 uses an independent analog signals for real and reactive load sharing. The Easygen uses a single CAN communication line for the same load sharing. As is, there is no way for them to share. However, there are Woodward devices called Load Share Gateways (LSG). There is a model for real power sharing and another for reactive power sharing. These gateways convert the Easygen CAN to SPM-D analog load sharing system. The LSG's will permit the Easygen and SPM-D to operated on a common bus.
First you need to specify what voltage you require the generator to supply...Lets Assume its 240 Volts AC. Watts=Volts x Amps so 240x1200= 28.8 Kw. Then you have to take the efficiency of the generator into account. Mechanical power in is usually quite a bit more than the electrical power you get out...The difference is mostly the mechanical and thermal losses added together. If we say the generator is 70% efficient then you will need a generator 30% more powerful to supply a constant 1200 Amps...Thats a generator of about 38-40 Kw.
The light system of paralleling generators has lamps hooked in series and connected between the hot lead of the lead generator and the hot lead of the lag generator. When one generator is running faster than the other one, the lights will blink off and on as the generators come in and out of phase with each other. Adjusting the throttle of the lag generator and bringing it closer to synchronise speed will cause the lights will start to pulsate slower and slower until they go off for a period of seconds and then on for a period of seconds. At this point the two generators are electrically paralleled. Count the time between on off on of the lights. At half the off time (zero voltage) throw the switch and the generators will lock together, the two generators will be running in parallel with each other. Manually to keep them paralleled requires a bit of work, as the faster generator will try and take the load and motor the other one. This is where a governor is a great asset. If the generators are tied together out of phase two things could happen. The least problematic would be the generators breaker will trip. The second and most dangerous is if the lag generator is just a little bit out of phase when the switch is thrown, then the generator will be jerked into phase lock as momentary heavy current flows between the two generators. The sudden loading of the generator has been known to break crankshafts of the engine driving it.
When you wish to bring a second generator on-line in order to do maintenance on the first one. They would be connected in parallel, but not yet switched on together, until you are sure they are both in phase. This is simply accomplished by connecting a light bulb between the Phase of one to the Neutral of the other. The bulb will wax and wane as the generators come in and out of phase. When the bulb is brightest, switch them together.
In a nut shell. Transfer switch senses incoming voltage (power company) through a relay. When relay drops out due to lack of voltage, contacts close and start the generator. When generator gets up to speed, second relay senses the generator's voltage and opens contactor that is connected to power company's incoming voltage. When that contactor is open, its auxiliary contact closes the generator contactor. The load side of both contactors are connected together to a load (could be a house, factory, hospital, machinery) With the generator contactor now closed the generator is supplying voltage to the load. Still with me? When the incoming (power company) voltage resumes, it energizes a timer until the power is stabilized, usually about 5 minutes. The timer contacts drop the generator contactor out, dropping the load for about a 1/4 of a second and re energises the incoming voltage contactor. The generator usually stays running up to 10 minutes to cool down and it then shuts its self off. The transfer switch is then ready for the next power failure. Some nut shell.
A simple Rotary phase converter is just a motor generator set. An electric motor running on the input voltage/current/phase/frequency. it drives a generator that supplies a different voltage/current/phase/frequency. So an electric motor and an electric generator connected together mechanically, either on the same shaft, or via gears, constitutes a Rotary phase converter. the above is incorrect, the motor/generator is the same motor, just one 3 phase motor is needed, it will run on T1 and T2, and put out L1, L2, and L3. You just need to know how to wire it up and what to do to get it to spin over on simple single phase 220, it will create three phase 220.
a series generator is 3 or 5 generator connected together
Not anymore, they broke up in 2011.
They had extreme anal bondage together.

Steam turbines run with a speed governor which responds to changes in turbine rotational speed and operates on the steam admission valves. Thus if the network that the turbine generator feeds has a change in frequency, the turbine responds. If extra load comes onto the network, the frequency drops slightly, the generator slows and the turbine must follow (they are solidly locked together) so that the governor then opens the steam valves to try to keep the speed steady. The converse happens if the network suddenly loses load.

Wait i forgot. i remember separately.
yes
They are used together to make hydroelectricity.
Because the governor wants to rule over everything
No, Florida is one of the 25 states that elect their governor and lieutenant governor on the same ticket. 18 states elect the governor and lieutenant governor separately, and there are other guidelines that apply to different states.
State voters elect the lieutenant governor. In most states, the governor and lieutenant governor are elected together on a single ticket, but other states vote for lieutenant governor separately, meaning he or she may be from a different party than the governor.
