Prime Power and Continuous Power of 250kW Diesel Generator

Prime power and continuous power of 250kW diesel generator

250KW diesel generator is a small power generation equipment, which refers to the power machinery that uses diesel as fuel and diesel engine as prime mover to drive the generator to generate electricity. The whole generator set is generally composed of diesel engine, alternator, control box, fuel tank, starting and control battery, protection device, emergency cabinet and other components.

When purchasing 250kW diesel generator set, it is not enough for users to only pay attention to its performance, price, fuel consumption, energy and other aspects. They also need to understand the key points of power selection of diesel generator set. Many users have a half understanding of this and confuse the role of prime power in diesel generator set.

Prime power

Prime power rating is applicable for supplying electric power in lieu of commercially purchased power. A 10% overload capablility is available for aperiod of 1 hour within a 12 hour period of operation. Total operating time at the 10% overload power shall not exceed 25 hours per year.

The prime power of 250 kW diesel generator is also called continuous power or long-distance power. In China, the prime power is generally used to identify diesel generator set, while in the world, the standby power, also known as maximum power, is used to identify the diesel generator set. Irresponsible manufacturers often use maximum power as continuous power to introduce and sell the genset in the market, causing many users to misunderstand these two concepts.

Continuous power

In our country, 250 kW diesel generator is nominal by the prime power, i.e. continuous power. The maximum power that the generator set can continuously use within 24 hours is called continuous power. In a certain period of time, the standard is that the genset power can be overloaded by 10% on the basis of continuous power every 12 hours. At this time, the diesel genset power is what we usually call the maximum power, i.e. standby power, that is, If you buy a 400KW diesel generator for main use, you can run to 440kw in one hour within 12 hours. If you buy a standby 400KW generator, if you don't require overload, you usually operate it at 400KW. In fact, the diesel generator has always been in overload state (because the actual prime ated power of the unit is only 360kw), which is very unfavorable to the generator, which will shorten the service life of the diesel genset and increase the failure rate.

Consumers should be reminded that most of them use standby power in the world, which is different from that in China. Therefore, irresponsible manufacturers often exchange their power in the market to introduce and sell units and deceive consumers. Be careful when buying diesel generator sets. Yangzhou Shengfeng is a professional manufacturer of diesel generator sets. If customers are confused about the power of diesel generator sets, they can call for consultation. Users are welcome to buy!

When purchasing a 250kw diesel generator, we should look at the prime power if you require prime power. But if you require standby power, will be standby power 250kw. 

The generators purchased by enterprises are used as standby power supply, but many enterprises do not know what kind of generators to buy or what brand of generators to use. Then let's take the 250KW diesel generator as an example to briefly introduce the misunderstanding when purchasing generators.

Generally, customers who buy 250KW diesel generators are mostly used as standby power supply. Such machines don't work much time. Therefore, we should pay attention to whether there are problems with the battery pack after long-term placement. The common problem is that after the battery pack of the 250KW diesel generator works, the sound of the solenoid valve can be heard, but it can not drive the operation of the coupling shaft, which means that the battery has voltage but can not produce current. This kind of situation happens more often. After the 250 kW diesel generator is used, the battery pack is not fully charged, and it is in a weak state for a long time, resulting in abnormal working state. The other is that the power of the battery pack is insufficient. After stopping the machine, the spring plate in the 250KW diesel generator cannot seal the fuel ejected from the spray hole, which makes the machine unable to stop, and finally makes 250KW diesel generator unable to work normally. Therefore, we must always maintain the battery pack and fully charge it, especially when it is not working. No matter how expensive the Yuchai generator is and how good the brand quality is, pay attention not to leave the machine idle.
