Parallel Generators 660-1100KVA
What is Running Generators in Parallel?
Simply put is when you connect two or more generators (our smartGen controllers come with the ability to connect 32 generators together) they can share the load of the power required
Why would you want load sharing parallel 2 generators
Let's say you owned a farm and with everything running at the same time requires 30 kVA generator, however, you don't often run everything at the same time but sometimes you do so by having 3 10 kVA generators connected in parallel each one will turn on or off as the power is required
What are starting Watts and running Watts, synchronous generators
Most people are aware of how many watts that is required to run a motor let's take an example a 13,000 BTU air-conditioner, to write this air conditioner requires approximately 3500 Watts however to start it requires almost 10,000 warts so if you had a 4 kVA generator you could not start this air conditioner
One excellent reason for synchronizing generators
unlike a car, generator engines have a consistent speed (Diesel generators 1500 rpm) and as more power is required from the alternator a heavier load is placed on the engine more horsepower is needed and it burns more fuel, however generators love Hardwork running at approximately 75% of its load capacity is ideal, however running more or less than that will shorten the generators life, if you have synchronized generators once the load capacity exceeds 75% it turns on the next generator, so all except the last generator will be running at its preferred load capacity
Servicing parallel generators
Just like cars generators need filters and oil changed, if you have only one generator then everything has to be shut down to give it a service, but with load sharing generators you can simply service the ones that are not in use.
Does Paralleling Cause Damage to Gensets?
Running parallel generators is not a problem as long as they are two generators that are designed to be run in this way. Furthermore, most generators require a particular parallel cable to make this work. The reason for this is that each generator has its own computer inside. They are not designed to work together among different manufacturers. This synchronization is often only possible if the manufacturers are the same such as Kruger.
The reliability in the parallel generators is greater than what is offered by a single generator unit for critical loads. If one unit fails, the critical loads are redistributed among other units in the system on a priority basis. Critical loads that need the highest degree of reliable backup power usually account for only a fraction of the overall power generated by the system. In a parallel system, this means that the most critical elements will have power even if one of the units goes out.
Kruger Genset Controller
Kruger Power uses only the best controller for syncing and all generators over 35kVA can be syncronised. The controller is installed for checking the parameters of the engine and the alternators of each unit in the system. Load control and scheduling generators to go on/off. The controller checks for proper synchronization, load and voltage balance, and reverse power functions. In traditional parallel operating systems, each of the generators has its own controller in addition to a master controller that governs the combined system.
Each of the controllers has to be installed so they control the working of the individual generator and have to be in sync with the working of the parallel system which is controlled by the master controller. In traditional, older parallel systems, there is also a lot of electric noise due to the simultaneous operation of multiple controllers. This causes a lot of disturbance and these systems are often predisposed to temporary collapse. Therefore, it requires constant supervision for consistent power supply during power failures, which is an added expense and obstacle to overcome.
One of the main issues with parallel generators is that they can be called so many different things like, generator synchronization, Paralleling Generators, generator paralleling, synchronised generators, synchronizing generators, synchronized generators, synchronous generators, load sharing generators, load sharing in parallel generators, Generator Load Sharing, generator paralleling and load sharing, Running Generators in Parallel, generators in parallel operation, at the end of the day its all the same thing, 2 or more generators switching on or off as the power requirement increases or decreases
