Hello!
When the diesel generator is operating, if it is not transmitting power, that is, if it is idle, its fuel consumption is fixed, representing approximately 0.5% of fuel consumption at rated power;
When the generator produces more electrical energy, it consumes more fuel. When the output reaches the rated load, the fuel consumption reaches the maximum. At this time, the loss reaches (1-5)% of the value. total power (the greater the generator power, the greater the proportion. The smaller it is, the smaller the power and the greater the proportion).
I hope you find it useful and I hope you adopt it.
The simplest method is to calculate based on your electricity meter, record the amount of electricity produced during a certain period of time, then divide it by the time, which is for example the power of your generator. , the number of electricity meters you record in one hour is 100 degrees, or 100 kilowatt hours, divided by one hour, the generator power is 100 kilowatts. I don't know which aspect you are talking about between the theoretical value and the real value. If the above calculation method is used, in addition to the influence of power factor and multiple reactive power, it is also more accurate. If we talk about the generator power calculated based on the head flow, then it is difficult to determine the actual difference in power generation which may be affected by the manufacturing process and construction of the flow channel of the spiral chamber of power plant.
