I want to install 4 sets of generator with synchronising system. During main goes off, the first set will start and the subsequent sets will start upon demand of load. Likewise, when load requirement goes lower, genrastor will start stop on the basis of demand.

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.

Burden sharing refers to the distribution of responsibilities or the allocation of tasks among individuals, organizations, or countries to collectively address a common challenge or problem. It emphasizes the idea of sharing the load and working together to achieve a common goal.
Paralleling generators involves connecting multiple generators to a common bus to share the electrical load. The procedure typically includes synchronizing the generators in terms of voltage, frequency, and phase before connecting them to the bus. Once synchronized, the generators can share the load based on their capabilities, with the load distribution influenced by their respective settings, such as governor control and droop settings. Proper load sharing is crucial to ensure that no single generator is overloaded, which can be managed through coordinated control systems that adjust output based on real-time load conditions.
Network load usually refers to the sharing of work between networked computers. A network can handle a much larger load when two or more computers are working together to balance traffic rather than relying on one computer server by itself.
Droop CT is used to control load sharing of the reactive power b/w paralleled generators.
Well kinda, You can load other profiles from sharing websites to get all items, if you dont know how the look it up on youtube
For parallel operation of let's say two transformers, following limiting conditions must be met. 1- The turn ratios must be same. 2- The percentage impedance must match. 3- The X/R ratios must be same. The load sharing is done according to the kVA ratings and %Z of the transformers. The formula is as under: load taken by TF1 = ((kVA1/%Z1)/((kVA1/%Z1)+(kVA2/%Z2)))*total load Similarly, load taken by TF2 = ((kVA2/%Z2)/((kVA1/%Z1)+(kVA2/%Z2)))*total load An example will make the concept easier. For example we have to parallel a 1000kVA TF of 5%Z with another of 1200kVA having 5.5%Z to supplay a load of 800kVA. load taken by TF1= ((1000/5)/((1000/5)+(1200/5.5)))*800= 382.6kVA load taken by TF2= ((1200/5.5)/((1000/5)+(1200/5.5)))*800= 417.4kVA
If twenty identical cables installed in parallel that do not evenly share the load, then you have some bad connections that are changing the resistance of one or more cables.
