相比汽油、燃气等能源，柴油蕴含能量高，单位体积与价格内，柴油发电机的发电运行成本也低很多，不过相比市电工业用电，除了购买发电机组的费用，它的发电成本也是要高一些的，尤其受柴油价格变化影响大，下面以一度电为例计算柴油发电机的发电运行成本。
Compared with gasoline, gas and other energy sources, diesel contains high energy. Within the unit volume and price, the operating cost of diesel generators is also much lower. However, compared with the electricity used in the municipal power industry, in addition to the cost of purchasing generator sets, its power generation cost is also higher, especially affected by the changes in diesel prices. The following is an example to calculate the operating cost of diesel generators.
柴油发电机的发电运行成本是多少
What is the operation cost of diesel generator
行业内通常以燃油消耗率（单位g/kw.h）来标定一台柴油发电机的油耗情况，其参数多在190-210g/kw.h之间，其中各因技术不同，燃油消耗率有一定差距，而各功率之间此参数差距较小，以198g/kw.h来计算油耗情况，如满载30KW的柴油发电机，其每小时油耗为30*198g=5.94kg，柴油密度约为0.8kg/L（各标号柴油密度略有不同），那么此柴油发电机每小时油耗换算为体积则为7.4L。
In the industry, the fuel consumption of a diesel generator is usually calibrated by the fuel consumption rate (unit: g/kw. h). Most of its parameters are between 190-210g/kw. h, among which, due to different technologies, there is a certain gap in the fuel consumption rate among brands, while the gap between these parameters is small. The fuel consumption is calculated by 198g/kw. h. For example, the fuel consumption per hour of a fully loaded 30KW diesel generator is 30 * 198g=5.94kg, The density of diesel oil is about 0.8kg/L (the density of diesel oil of different grades is slightly different), so the hourly fuel consumption of this diesel generator is 7.4L.
按照柴油常年的平均价格6元/l计算，输出30度电的柴油成本为7.4*6=44.4元，即每度电成本为44.4÷30=1.48元，相比电网工业用电电费的1.1元左右多一些。

According to the annual average price of diesel oil of 6 yuan/l, the cost of diesel oil to output 30 kilowatt hours of electricity is 7.4 * 6=44.4 yuan, that is, the cost per kilowatt hour of electricity is 44.4 ÷ 30=1.48 yuan, which is more than about 1.1 yuan of electricity charge for power grid industry.
除了柴油消耗，柴油发电机的运行成本还要考虑机械磨损维护、机油消耗等，在选择发电机组时要根据实际情况，如使用比较频繁的情况下，可以选择大发电机组，它的燃油消耗率通常会低一些，设备也耐用，而很少使用的情况下，可以选择质量可靠的机组厂家，购买费用会低很多。
In addition to diesel oil consumption, the operating cost of diesel generator should also consider mechanical wear maintenance, oil consumption, etc. When selecting generator sets, it should be based on the actual situation. For example, if the generator sets are used frequently, large brand generator sets can be selected. Its fuel consumption rate is usually lower, and the equipment is durable. If the generator sets are rarely used, the generator set manufacturers with reliable quality can be selected, and the purchase cost will be much lower.
