Can the generator run parallel? What are the conditions for parallel connection?

The procedure of numerous generator sets can fulfill the requirements of lots adjustments as well as greatly minimize the operating expense of the generator collection. Consequently, there are an increasing number of demand for identical link in the market in the marketplace.

Theoretically, the problems for the parallel procedure of the concurrent generator are: the very same series, voltage, as well as frequency of the generator staff and also the job generator set are the same, and also the first stage is equivalent. As a matter of fact, the generator sets that remain in parallel do not totally meet the above conditions. It is just within the permitted variety of voltage distinctions, frequency difference, as well as bonest stage angle.

But you can't attach casually! Mainly the regularity is not integrated as well as the voltage discrepancy.

The parallel procedure conditions of the simultaneous generator are:

⑴ The voltage proportion coincides, as well as the allowable distinction is ± 0.5%; ⑵ The percentage impedance is equal, as well as the permitted difference is ± 10%; ⑶ The electrical wiring team coincides. If the voltage proportion is various, the two transformers running alongside will generate a circulation, which will affect the power of the transformer. If the portion insusceptibility is different, the tons of the transformer can not be distributed proportional according to the capacity of the transformer. The load of the transformer belt with much less resistance will also influence the contribution of the transformer. The transformer runs alongside with the very same voltage proportion and insufficient percent insusceptibility, and usually boosts the approach of altering the joint. The electrical wiring group should also correspond, otherwise it will certainly create short circuit. If the team is irregular as well as meets particular problems (the very same is the single selection or the exact same double array), it can be regular by transforming the technique of altering the exterior electrical wiring.

The serial link of the generator can just raise the voltage. The more the generator links, the higher the voltage, and also the user needs a steady voltage, which is inconsistent. And also as long as it is detached in the collection circuit The power supply is unchanged, and the current can raise, that is, the ability raises, and also a certain motor is shut down for one reason or another, and also it will certainly not influence various other. In the previous voltage, the voltage in between the lines of all electric devices as well as completion end of the line coincided, that is, the voltage used between the electric devices made use of in the parallel circuit was equivalent, but the current that different electrical home appliances moved as a result of different inner resistance, then the existing flowed by various resistance, then the existing streamed by different electrical devices, after that the present flowing with the interior resistance, then the existing flowed by different electrical appliances, then the present streaming via the internal resistance, after that the present streaming with the present, then the existing streaming via the present, after that the present flowing with the existing, then the current streaming through the current, after that the present moving through the present. Different, that is, the phenomenon of parallel circuit.

If a voltage is included in between the electric inspiration end as well as completion end of the electrical device in the parallel circuit, after that the voltage between the lines of all electric home appliances and the end of the line coincides, that is Equal, yet different electric devices flow differently because of different inner resistance, that is, the diversion of parallel circuits.
