There are two types of generator sets: diesel and gasoline. Gasoline generators are mostly used on small internal combustion engines and are suitable for some household generators. Diesel generators use water as the cooling medium, and there are two types separate types and closed types, which are suitable for various environments such as commercial, residential, construction sites, and outdoor construction.
When users use diesel generators to generate electricity, they may be more concerned about the cost of diesel generators. So let’s do a simple analysis today.
To understand the cost of a diesel unit, it can be calculated by fuel consumption rate and fuel consumption:
Calculate 30kw, 100kw, One-hour fuel consumption of 500kw and 1000kw units. Generally, 1L diesel oil is about 0.8kg;
30kw diesel generator set fuel consumption=30×198÷0.8=7425 (ML)=7.4L=5.92kg;
100kw generator set fuel consumption=100×198÷0.8=24.75 liters (L)=19.8kg;
Fuel consumption of 500kw generator set=500×198÷0.8=123.75 liters (L)=99kg
The diesel consumption of a 500 kW diesel unit is 123.75L, the diesel price is 6 yuan/L, the cost of purchasing or leasing a diesel unit is 8284.43USD per month (the machine works 8 hours a day); the labor wage is 27.61USD/day (in China, the specific It needs to be combined with local labor costs), assuming that the actual output power is 400 kWh (500kw*0.8 power factor). Actual fuel consumption: 123.75L*0.8=99L
Diesel unit diesel cost calculation: 99L×0.83USD=82.02USD
82.02USD÷400kw=0.21USD/kw.h
Labor wage cost: 27.61USD/day ÷ 8 hours ÷ 400kw=0.01USD/kw.h
It can be calculated that the power generation cost of a 500kw diesel generator is about: 0.21+0.01=0.22USD, which is about 0.2USD.
The fuel consumption rate and actual output power of 500kw diesel generators are different, which also has a certain impact on the calculation of power generation costs. If you want to use a unit machine to generate electricity at a lower cost, you can choose a low-fuel consumption generator. Generators with low fuel consumption cost more to purchase, but the running cost of diesel is relatively low later.
