Regulating characteristics:

 Voltage regulation and frequency regulation are different: in a system, the frequency value is the same regardless of the region, the balance of active power is the balance of the whole system; The voltage level is not consistent in different areas of electricity consumption, reactive power balance is mainly in different areas of balance, power plant voltage regulation ability can only reach a small area around it.. Generator in parallel operation, more of a unit used this method to adjust the function of frequency and voltage for the system was not significant, it mainly is to adjust the load distribution between the group, especially in a large system of small units, output size not happen a material impact on voltage and frequency, can be adjusted according to the need of unit. So the regulation of a small generator connected to the grid is much simpler.

 When the active power output of the generator is maintained unchanged, the reactive power output and power factor of the generator can be changed by changing the excitation. When the excitation current remains unchanged, increase the active power output, the reactive power output of the generator will decrease, if it is not reduced, it must increase the excitation accordingly.

Basic structure:

The basic structure of diesel generator is composed of diesel engine and generator, and the diesel engine drives the generator to generate electricity.

The basic structure of diesel engine: composed of cylinder, piston, cylinder head, intake valve, exhaust valve, piston pin, connecting rod, crankshaft, bearing and flywheel and other components. The diesel engine of the diesel generator is generally a single cylinder or multi-cylinder four-stroke diesel engine. The following I just talk about the basic principle of the single-cylinder four-stroke diesel engine: The diesel engine starting is to rotate the crankshaft of the diesel engine by manpower or other power to make the piston in the top closed cylinder for up and down reciproCAT-parts-partsing motion. The piston completes four strokes in motion: intake stroke, compression stroke, combustion and work (expansion) stroke and exhaust stroke. When the piston moves from up to down, the intake valve opens, and the fresh air filtered by the air filter enters the cylinder to complete the intake stroke. The piston moves from the bottom up, the inlet and exhaust doors are closed, the air is compressed, the temperature and pressure are increased, and the compression process is completed. When the piston is about to reach the apex, the injector will spray the filtered fuel into the combustion chamber in the shape of a mist and mix with the air of high temperature and high pressure. The high pressure formed will push the piston down to work, push the crankshaft to rotate, and complete the work stroke. After the work stroke is finished, the piston moves from the bottom up, and the exhaust valve opens the exhaust to complete the exhaust stroke. Each stroke of the crankshaft rotates half a turn. After several working cycles, the diesel engine gradually accelerates to work under the inertia of the flywheel.
