Technical Questions And Answers About Diesel Generators (3)
16. How to calculate the current of a three-phase generator? Answer: I = P / (√3 Ucos φ) That is, current = power (watts) / (√3 *400(volt) * 0.8). The simplified formula is: I (A) = unit rated power (KW) * 1.8 17. What is the relationship between apparent power, active power, rated power, maximum power, and economic power? Answer: 1) The unit of apparent power is KVA, which is used to express the capacity of transformers and UPS in our country. 2) The active power is 0.8 times the apparent power, the unit is KW. my country is used to power generation equipment and electrical equipment. 3) The rated power of a diesel generator set refers to the power that can be operated continuously for 12 hours. 4) The maximum power is 1.1 times the rated power, but only 1 hour is allowed within 12 hours. 5) The economic power is 0.75 times the rated power, which is the output power that the diesel generator set can run for a long time without time limitation. When running at this power, the fuel is the least and the failure rate is the lowest. 18. Why is it not allowed for diesel generator sets to run for a long time when the power is less than 50% of the rated power. Answer: Increased oil consumption makes diesel engines prone to carbon formation, which increases the failure rate and shortens the overhaul period. 19. The actual output power of the generator during operation is based on the wattmeter or the ammeter? Answer: The ammeter shall prevail, and the power meter is for reference only. 20. The frequency and voltage of a generator set are both unstable. Is the problem with the engine or the generator? Answer: It lies in the engine. 21. The frequency of a generator set is stable, but the voltage is unstable. The problem is the engine or the generator? Answer: It lies in the generator. 22. What is the loss of magnetism of the generator and how to deal with it? Answer: The generator is not used for a long time, causing the remanence contained in the iron core to be lost before leaving the factory, and the excitation coil cannot build the proper magnetic field. At this time, the engine is running normally but no electricity is generated. This kind of phenomenon is a new machine. Or there are more units that have not been used for a long time. Solution: 1) Press the excitation button once if there is an excitation button, 2) if there is no excitation button, use a battery to magnetize it, 3) load a light bulb and run it at overspeed for a few seconds. 23. After the generator set has been used for a period of time, it is found that everything else is normal but the power drops. What is the main reason? Answer: a. The air filter is too dirty and the intake air is not enough. At this time, the air filter must be cleaned or replaced. b. The fuel filter device is too dirty and the fuel injection volume is not enough, so it must be replaced or cleaned. c. The ignition time is not correct and must be adjusted. 24. After a generator set is loaded, its voltage and frequency are stable, but the current is unstable. What is the problem? Answer: The problem is that the customer's load is unstable, and the quality of the generator is absolutely fine. 25. The frequency of a generator set is unstable. What is the main problem? Answer: The main problem lies in the unstable speed of the generator. [View Details]

6. What problems should be paid attention to when using the unit with ungrounded neutral point? Answer: The 0 line may be charged because the capacitor voltage between the live line and the neutral point cannot be eliminated. The operator must regard the 0 line as a charged body. It cannot be handled according to utility power habits. 7. How to match the power of UPS and diesel generator to ensure stable output of UPS? Answer: 1) UPS is generally expressed in apparent power KVA, first multiply it by 0.8 and convert it to the unit KW which is consistent with the generator's active power. 2) If a general generator is used, the active power of the UPS is multiplied by 2 to determine the power of the generator, that is, the power of the generator is twice the power of the UPS. 3) If a generator with PMG (permanent magnet machine excitation) is used, the UPS power is multiplied by 1.2 to determine the generator power, that is, the generator power is 1.2 times the UPS power. 8. Can electronic or electrical components marked with a withstand voltage of 500V be used in diesel generator control cabinets? Answer: No. Because the 400/230V voltage marked on the diesel generator set is the effective voltage. Its peak voltage is 1.414 times the effective voltage. That is, the peak voltage of the diesel generator is Umax=566/325V. 9. Do all diesel generator sets have self-protection function? Answer: No. At present, there are even some units of the same brand in the market, and some do not. The user must figure it out by himself when purchasing the unit. It is best to write in written materials as an attachment to the contract. Generally, low-cost machines do not have self-protection function. 10. How to identify fake, inferior and counterfeit domestic diesel engines? Answer: First check whether there is a factory certificate and a product certificate. These are the "identity certificates" for the diesel engine to leave the factory and are required. Check the three major numbers on the certificate again: 1) nameplate number; 2) body number (the actual product is usually on the plane machined at the flywheel end, the font is convex); 3) the oil pump nameplate number. Check these three numbers with the actual numbers on the diesel engine, and they must be accurate. If any doubts are found, these three numbers can be reported to the manufacturer for verification. 11. After the operating electrician takes over the diesel generator set, which three points must first be verified? Answer: 1) Verify the real useful power of the unit. Then determine the economic power and reserve power. The method of approving the real useful power of the unit is: the 12-hour rated power of the diesel engine is multiplied by 0.9 to obtain a data (kw). If the rated power of the generator is less than or equal to this data, the rated power of the generator is regarded as the real useful power of the unit. If the rated power of the generator is greater than this data, this data must be used as the real useful power of the unit. 2) Verify which self-protection functions the unit has. 3) Check whether the power wiring of the unit is qualified, whether the protective grounding is reliable, and whether the three-phase load is basically balanced. 12. There is an elevator starting motor of 22KW, what size generator set should it be equipped with? Answer: 22*7=154KW (the elevator is a direct load starting model, and the instantaneous starting current is generally 7 times the rated current to ensure that the elevator moves at a constant speed). (That is, it should be equipped with a generator set of at least 154KW) 13. How to calculate the optimal power (economic power) of the generator set? Answer: P is best = 3/4*P rated (that is, 0.75 times the rated power). 14. According to the national regulations, how much higher the engine power of a general generator set should be than the generator power? Answer: 10℅. 15. The engine power of some generator sets is expressed in horsepower. How to convert horsepower to international unit kilowatts? Answer: 1 horsepower = 0.735 kilowatts, 1 kilowatt = 1.36 horsepower.

Technical Questions And Answers About Diesel Generators (1)
1. What are the conditions for the parallel use of two generator sets? What device is used to complete the parallel work? Answer: The condition for parallel use is that the instantaneous voltage, frequency and phase of the two machines are the same. Commonly known as "three simultaneous". Use a dedicated parallel device to complete the parallel work. It is generally recommended to use fully automatic cabinets. Try not to manually parallel. Because the success or failure of manual paralleling depends on human experience. With more than 20 years of experience in electric power work, the author boldly stated that the reliable success rate of manual parallel diesel generators is equal to zero. Never use the concept of manual paralleling for large mains power supply systems to apply small power supply systems, because the protection levels of the two are completely different. 2. What is the power factor of the three phase generator? Can a power compensator be added to improve the power factor? Answer: The power factor is 0.8. No, because the charging and discharging of the capacitor will cause the fluctuation of the small power supply. And the unit oscillates. 3. Why do we require customers to tighten all electrical contact parts every 200 hours of operation? Answer: Diesel generator set is a vibrating working device. Moreover, many domestically produced or assembled units should use double nuts which are useless. The use of spring washers is useless. Once the electrical fasteners are loosened, a large contact resistance will be generated, which will cause the unit to operate abnormally. 4. Why must the generator room be clean and free of floating sand on the ground? Answer: If the diesel engine sucks in dirty air, the power will decrease; if the generator sucks in sand and other impurities, the insulation between the stator and rotor gaps will be damaged, and the worst will cause burnout. 5. Why our company generally does not recommend users to use neutral point grounding during installation? Answer: 1) The self-regulating function of the new generation generator is greatly enhanced; 2) In practice, it is found that the lightning failure rate of the neutral-grounded unit is relatively high. 3) The grounding quality requirements are high, and ordinary users cannot do it. Unsafe working grounding is not as good as ungrounding. 4) Units whose neutral point is grounded will cover up the leakage faults and grounding errors of the load, and these faults and errors cannot be exposed under the condition of large current supply from the mains.
