5 Key Factors Affecting The Rated Output of Diesel Generators

Due to adverse weather conditions, power line failures, and power supply shortages, the threat of power outages has become increasingly common in many places, putting pressure on the current power grids.

As a commercial real estate owner, it is crucial to equip industrial diesel generators. Having a backup power source can avoid maintenance issues and profit losses. However, first you need to understand one or two things about the output rating of diesel generators. The rated value of a diesel generator determines how much electricity it can generate at full load under optimal conditions.

It is not always easy to determine the output rating of a diesel generator. Continue reading to learn about five factors that may affect the rated output of diesel generators, including those that cause a decrease in rated value.

When manufacturing diesel generators, the manufacturer will specify the output rating of the diesel generator. The rated value determines the maximum energy output of the diesel generator when operating in the optimal environment. Generally speaking, this means that diesel generators are located at sea level with moderate temperature and pressure levels.

When considering the output rating of a manufacturer's diesel generator, the size of the engine will have a significant impact. The size of a diesel generator engine paired with its maximum output can also be referred to as capacity.

The first step in selecting a suitable diesel generator is to ensure that it has the capacity or rated output power to power the entire commercial building. But please remember that most of the time, you need to run the diesel generator at around 80% power to save fuel and avoid maintenance issues. Only in emergency situations would you want to start the diesel generator to 100%.

The engine size is not the only factor determining the rated output of a diesel generator. In fact, you may encounter diesel generators with the same size engine but different output ratings, as efficiency also plays an important role.

Diesel generators are a more efficient choice because diesel has a much higher peak energy density than natural gas. In other words, diesel produces more electricity output per liter than natural gas.

Although the cost per liter of diesel is higher than that of natural gas, the cost of diesel generators is often lower. Due to improved efficiency, more energy will actually be obtained. In addition, with proper maintenance, the service life of diesel generators is longer.

As we mentioned earlier, the initial diesel generator output rating of an industrial diesel generator is related to its maximum capacity under optimal conditions. What happens when these conditions are no longer optimal? The working efficiency of diesel generators begins to decrease, leading to the so-called derating.

The external temperature is not the only issue. If the diesel generator cannot ventilate properly to keep the internal structure cool, the diesel generator may overheat. Ventilation is controlled by a diesel generator:

Radiator

Air intake system

Exhaust system

If the diesel generator overheats, it may cause serious damage to many institutions, and the cost of repair or replacement may be high. You can prevent overheating by performing basic maintenance, such as replenishing coolant, adding an appropriate amount of fuel to the diesel generator, and cleaning components such as air filters and engine parts.
