Question 1

How to convert the power of diesel generator in kW to kVA?

Accepted Answer

Active Power (kW) quantifies actual work output, where 1kW = 1kWh for direct energy billing. Apparent Power (kVA) represents total system capacity, serving as the universal engineering benchmark. Convert with: kVA = kW / Power Factor. Example: 90kW / 0.9 PF = 100kVA rated output. Proper Usage Notes for Diesel Generator Set: Fuel selection: Use standard 0# or -10# diesel (depending on the temperature). Installation environment: Ensure good ventilation and avoid dust and moisture. Regular maintenance: Replace the engine oil every 500 hours and check the coolant and battery.

Question 2

What are the conditions for operating diesel generator sets in parallel?

Accepted Answer

The conditions for using the parallel operation system are that the voltages, frequencies, and currents for the two diesel generator sets must be consistent at the same time. The parallel operation of the diesel generator sets is accomplished by using a dedicated parallel operation device. It is generally recommended to use an automatic parallel cabinet. Try not to use manual parallel operation. The success or failure of manual parallel operation depends on human experience.

Question 3

What does the power rating of diesel generator mean?

Accepted Answer

The power rating of a diesel generator will tell you how much electrical load a generator can safely handle. It is typically displayed in kVA or kW and helps users comprehend if the generator fits their needs or not. There are different types of power ratings like prime power, standby power and continuous power. Prime power is used where the generator is operated for long hours with varying loads. Standby power is for use in case of an emergency in the event of power cuts, and is not intended to be used constantly. Continuous power is used where the generator is running at a constant load all the time. Understanding the power rating is important as overloading a generator can lead to overheating, high fuel consumption, and equipment damage.

Question 4

How much fuel does a diesel generator consume when it is running?

Accepted Answer

Fuel consumption of diesel generator depends on the size, load level and working hours. A generator with a low load on it will consume less fuel, and a generator that is near full output will also consume more diesel. Fuel consumption is typically measured in litres per hour. For example, a small diesel generator may only use a few litres per hour, whereas large industrial generators may use much more. Running a generator at around 70 to 80 percent load is considered ideal as it offers good efficiency and less wastage of fuel. Very low load operation can be detrimental as well, in that it can lead to carbon build-up inside the engine.

Question 5

Why should a diesel generator be maintained regularly?

Accepted Answer

Regular maintenance is necessary to ensure that a diesel generator operates smoothly and reliably. A well-maintained generator starts quickly, provides a stable power supply, and lasts longer. Without proper maintenance, minor problems can become major problems that lead to breakdowns or total failure. Maintenance includes checking engine oil, coolant levels, air filters, fuel filters and battery condition. Oil changes are particularly important as old oil can damage engine parts. Filters must be cleaned/replaced to ensure proper airflow and fuel supply. Batteries should also be tested regularly to avoid starting issues.

Question 6

What is power factor in diesel generator and why is power factor important?

Accepted Answer

Power factor indicates the level of efficiency a diesel generator has in converting the fuel into usable electrical power. It is most often represented by a number between 0 and 1. Most diesel generators are set up so that the power factor is 0.8 or 0.9, depending on the application. A low power factor indicates that the generator is providing more apparent power than usable power. This can result in increased current, losses and decreased efficiency. Many electrical loads, like motors and air conditioners, decrease power factor, as they are reactive power loads. The power factor helps in determining the right generator size.

Question 7

Why Diesel Generators run in parallel?

Accepted Answer

Diesel generators operate in parallel when multiple generators work in conjunction with each other to provide a system with electricity. This technique is widely used in industries, hospitals and data centres where power demand is high and reliability is essential. Parallel operation gives load sharing among generators, which enhances efficiency and reduces wear on individual units. It also allows for flexibility. If there is a surge in demand for power, more generators can be added. If one needs maintenance, others can keep running without interrupting the power supply. Generators in parallel operation also result in improved fuel efficiency as generators can be operated closer to their optimum load range.
