Diesel generator set is the most widely used power generation equipment at present. Many enterprises are equipped with diesel generator set as emergency standby power supply, and the price of one set is not cheap. Is the cost of using diesel generator set cost-effective? We know that the power generation cost of diesel generator set mainly includes the following aspects:

柴油成本；

Diesel cost;

购买发电机成本；

Cost of purchasing generator;

维护发电机成本；

Maintenance cost of generator;

发电机操作员工资；

Generator operator salary;

柴油发电机组是以柴油为燃料，也是后期的主要成本，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。

Diesel generator sets use diesel as fuel, which is also the main cost in the later stage. In the industry, the fuel consumption of a diesel generator is usually calibrated by the fuel consumption rate (unit: g/kw. h), and its parameters are mostly between 190-210g/kw. h. Among them, the fuel consumption rate of different brands has a certain gap due to different technologies.

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 consumption, the operating cost of diesel generator should also consider the mechanical wear and maintenance oil consumption, etc. When selecting the generator set, it should be based on the actual situation. For example, in the case of frequent use, large brand generator sets can be selected. Its fuel consumption rate is usually lower, and the equipment is also durable. In the case of infrequent use, the unit manufacturer with reliable quality can be selected, and the purchase cost will be much lower.

而要想降低柴油发电机组的发电成本，柴油发电机组的维护保养工作必不可少，正确及时仔细地维护保养，可保证柴油发电机正常工作，减少磨损，防止发生故障，延长机组使用寿命，降低运营成本，柴油发电机组的维护保养一般分为日常维护保养一级保养（每工作100小时）二级保养（每工作250~500小时）和三级保养（每工作1500~2000小时），不同的维保阶段有不同的维保项目，用户应根据不同阶段进行保养，可确保机组保持良好运行状态。

In order to reduce the power generation cost of the diesel generator set, the maintenance of the diesel generator set is essential. Correct and timely and careful maintenance can ensure the normal operation of the diesel generator, reduce wear and tear, prevent failure, extend the service life of the unit, and reduce the operating cost, The maintenance of diesel generator set is generally divided into daily maintenance level 1 (every 100 hours of work) level 2 (every 250~500 hours of work) and level 3 (every 1500~2000 hours of work). Different maintenance stages have different maintenance items, and users should carry out maintenance according to different stages to ensure that the unit is in good operation.
