A chinese diesel generator is the combination of a diesel engine with an electrical generator (often called an alternator) to generate electric energy. Diesel generating sets are used in places without connection to the power grid or as emergency power-supply if the grid fails. A Chinese generator is pretty much the same as a regular generator. Besides the fact that it is made in China there isn't a big difference in how they function.
There is only one thing that can be done if DC shunt generator fails to build up. The only thing that can be done is to disconnect the generator from the prime mover.
when excitation fails,Reactive power will be supplied by the system to which the generator is connected and generator will work as induction generator and its speed will rise a little. generator which was in over excitation mode will work in underexcitation.but there is under excitation limit which should not be reached so we should detect loss of excitation and trip generator
A diesel generator is important for businesses that often operate in areas where electricity is not available or when their offices are located in areas where the power often fails due to storms or infrastructure problems. Two types of diesel generator are available: standby units and portable units. Both types can be vital to your company. A diesel generator configured as a standby power source automatically starts and goes on line when its circuitry detects power irregularities. These are usually permanently installed units meant for single site operation. Standby generators are available in different sizes ranging from fewer than 10 kilowatts to several hundred kilowatts of power. Prior to purchase, you should have professionals measure the electric load of your site to make sure that the standby generator you buy is big enough. Because of the complexity of a standby diesel generator, you should probably have the unit professionally installed. A portable diesel generator is usually smaller than most standby units. These can easily be transported to different locations such as construction sites, disaster areas, or remote locations where no access to the electric utility is available. Although portable generators are available with capacities as low as 1 kilowatt, units that produce as many as 200 kilowatts are available. Before buying, you should evaluate the generating capacity required for your typical application. You should also make sure that you have a vehicle available with enough strength to move it. Other options also come into play while shopping for a diesel generator. For example, you may have to choose between a model that is air cooled and a model that is liquid cooled. Air cooled models are usually less expensive, although they normally operate at higher RPMs and are noisier than liquid cooled models. The voltage required should also be considered. A diesel generator may produce 120 volts (normal household power), 240 volts (for appliances, air conditioners, etc.), or three phase (for industrial applications). A generator that produces the wrong voltage is going to be useless to you and could damage equipment, so checking on the voltage you need is an important step in the purchasing process.
The word "standby" is used in 2 ways. 1) A standby generator is essentially a spare power source for when the main one fails. Usually cuts in automatically. 2) Kubota J series (and others?) say eg Prime output is 10kVA, and Standby output is 11kVA. I presume this means you can get 11kVA, but not good for the engine.

When it fails or starts showing signs of failure.
It acts as synchronous motor by consuming power from the other generator....
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.
A generator transfer switch is used to switch an electrical load between different sources such as grid power and a standby generator or between multiple generators to allow for maintenance of a generator in a set. These switches can be automatic, switching between sources when a source fails or moves out of specification or they can be manual, requiring operator intervention.
Your local Ford car dealership should have diesel trucks for sale. Just check around your town's car dealerships if the Ford option fails. I would not recommend looking online for a diesel truck, that would be hard to ship!
