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;

購買發電機成本；

Cost of purchasing generator;

維護發電機成本；

Maintenance cost of generator;

發電機操作員工資；

Generator operator salary;

柴油發電機組是以柴油為燃料，也是后期的主要成本，行業內通常以燃油消耗率（單位g/kw.h）來標定一臺柴油發電機的油耗情況，其參數多在190-210g/kw.h之間，其中各因技術不同，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，柴油發電機的運行成本還要考慮機械磨損維護機油消耗等，在選擇發電機組時要根據實際情況，如使用比較頻繁的情況下，可以選擇大發電機組，它的燃油消耗率通常會低一些，設備也耐用，而很少使用的情況下，可以選擇質量可靠的機組廠家，購買費用會低很多。

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.

而要想降低柴油發電機組的發電成本，柴油發電機組的維護保養工作必不可少，正確及時仔細地維護保養，可保證柴油發電機正常工作，減少磨損，防止發生故障，延長機組使用壽命，降低運營成本，柴油發電機組的維護保養一般分為日常維護保養一級保養（每工作100小時）二級保養（每工作250~500小時）和三級保養（每工作1500~2000小時），不同的維保階段有不同的維保項目，用戶應根據不同階段進行保養，可確保機組保持良好運行狀態。

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.
