To calculate the power of a diesel generator set, if your load power is relatively stable and there are no issues with starting current, you can choose a generator set power about 20% larger than the load. This is because a generator set with too little power may not handle load fluctuations well, and considering long-term development, the load is expected to increase. If you are only using it as an emergency generator, then only consider the capacity of the emergency load under accident conditions. If your load is very small, only a few thousand watts, then consider the cost-performance ratio, as doubling the capacity does not necessarily double the price. Generator power is easy to choose, but brands vary greatly in price, mainly considering your usage. If it's a main unit used 24/7, I recommend Caterpillar, Volvo, Cummins, or Perkins generator sets, as they offer guaranteed quality and after-sales service, although they are a bit expensive, which is a case of "you get what you pay for."

It's widely known that the power factor of generator sets is 0.8, but few understand why it's 0.8 instead of 1. Here's a breakdown of how the power factor of a diesel generator set is calculated: In the power triangle, the ratio of active power P to apparent power S is called the power factor cosφ. The formula is: S (apparent power)² = P (active power)² + Q (reactive power)². Therefore, P = S × cosφ, which simplifies to: cosφ = P/S = P/[√(P² + Q²)]. If using trigonometric functions, it gets even easier. By deriving the power angle from the power factor, we have: Q = P × ctgφ. In the operation of power grids, the power factor reflects how effectively the apparent power output by the power source is utilized. Ideally, we want the power factor to be as high as possible. This way, the reactive power in the circuit can be minimized, and most of the apparent power is used to supply active power, thus improving the power transmission efficiency. From the above data, it's clear that when customers purchase generator sets, they should also consider the power factor of 0.8.
