Today we give you a brief introduction to the diesel generator set in the plateau area to use power calculation method content.
Power per 1000m in plateau area decreased by 5; How to calculate the power of diesel generator set? If your load power is relatively stable and there is no starting current problem, choose a diesel generator set with a power of about 20* of the load. Because diesel generator power is too small, load fluctuation stability is poor, consider long-term development load increase. If only used as emergency diesel generator set, only the capacity of emergency load in case of accident is considered.
If your load is small, just a few kilowatts, consider cost performance because the capacity is double, but the price is not double. Generator power is easy to choose, but the price varies greatly from brand to brand, mainly consider your use, if it is mainframe, 24 hours, I suggest or Caterpillar, Volvo, Cummins, Perkins diesel generator set, quality assurance, after-sales guarantee, the price is more expensive, so a penny.
It is well known that the power factor of a diesel generator set is but I do not understand why it is 0.8, instead of continuous operation listed the calculation method of the power factor of a diesel generator set: In the power triangle, the ratio of power P and apparent power S is called power factor cosφ, and its calculation formula is S(apparent power) square =P(power) square Q(no power) square P=S×cosφ, namely: cosφ=P/S=P/[(P2 Q2).
If the trigonometric function is used to calculate, it is easier to use the power factor to derive the power Angle: Q=P×ctgφ. In the operation of the power grid, the power factor reflects the best use of power output, we hope that the greater the power factor, the better. In this way, the reactive power in the circuit can be reduced to a small level, treating most of the power as providing active power, thus increasing the power delivered by electrical energy. From the above data, it can be seen that when customers buy diesel generator sets, the power factor should be 0.1 also taken into account.
