Is Reactive Power Harmful to Diesel Generator

As we know, there are three kinds of power in power system of diesel generator: active power, reactive power, apparent power, they have some certain relationships. Active power is used for acting. Active power can be transformed into mechanical energy, thermal energy, light energy and other energy forms that we need. But what role does reactive power play in energy conversion? Even if we consume reactive power, the power supply company does not charge us for it. And the important point is that the existence of reactive power requires the design of the transformers need to increase the capacity, increase the cross-section area of conductors, so that we spend a lot of money. It seem that reactive power has little benefit to us, all harm. So whether reactive power is really useless? Today Starlight Power answers for you. Firstly, we learn what is reactive power in diesel genset. Reactive power is more abstract. It is used for electric field and magnetic field in the circuit...

How to stop diesel generator in case of emergency

800kw Perkins generator manufacturer tells you how to operate emergency shutdown. How to stop diesel generators in case of emergency. Do you cut off the power directly? There are normal shutdown and emergency shutdown, the article mainly talks about emergency shutdown operation. During the use of diesel generator set, because operators are negligent in maintenance or diesel generators long-term overloaded work, there will be some unexpected situations, as follows: 1.During the operation, the diesel engine suddenly changes its sound, the   oil pressure   drops or there is no oil pressure directly. It is possible that the high pressure oil pump is damaged and emergency stop is required; 2.Observe the meter speed, if the speed automatically rises or stays high, it is very likely that there will be a flying phenomenon; 3.After working for a period of time, the genset temperature rises sharply, or it is failure to start up. The reasons are mainly poor cooli...

Why does diesel genset lose excitation

Generator loss of excitation fault means that the excitation current provided by the excitation system suddenly disappears completely or partially. After the synchronous generator is out of magnetic, it will be transferred to the asynchronous running state, and the reactive power will be absorbed from the original reactive power conversion. The causes of generator loss of magnetism fault are: generator rotor winding fault, excitation system fault, automatic demagnetization switch trip and circuit fault. The effect of generator loss of excitation on the system: 1. Low-excitation and magnetic-loss generators absorb reactive power from the system, causing the voltage of the power system to decrease. If the reactive power reserve in the power system is insufficient, the voltage in some adjacent points in the power system will be lower than the allowable value, which destroys the stable operation between the load and each power supply, and even collapses the power system voltage. ...

Cummins Power Unveiled at Indonesian Electric Power Show

From September 11 to 14, the 2019 Indonesia Electric Power Exhibition kicked off in Jakarta. In order to meet the needs of the Indonesian market, consolidate the existing cooperative relationship, help partners, and explore potential customers, Cummins Power Technology Co., Ltd. also unveiled new power point products to lay a solid foundation for the development of the Indonesian market. In this exhibition, Cummins Power Tehcnology (CPT) exhibited 4BT3.9-G11, 6LTAA9.5-G1, QSZ13-G3 and other power products, which provides practical and effective solutions for the key point of low cost, high efficiency, and high quality in the current Indonesian market. During the exhibition, Cummins Power booth attracted a large number of visitors. Cummins staff always communicated with enthusiasm and patience, and answered customers' detailed questions about products anti-counterfeiting system, service channel network and other key issues. Many customers benefited from on-site consultation...
