Diesel Generator Tech

This article continues to introduce the calculation method of impulse current for parallel operation of diesel generators. The expression of the transient inrush current during the no - load connection of a doubly - fed induction generator is derived. The influence of the voltage amplitude difference and the phase difference on the inrush current is analyzed, and corresponding measures to suppress the inrush current are proposed. When a three - phase synchronous generator operates symmetrically, the effect of a single - phase can be equivalently considered. Through the finite - element modeling of a single - phase generator, it is verified that the frequency difference has little influence on the inrush current. The closing operation for paralleling does not select the moment when the frequency between the generator and the system is the same. A slight frequency difference makes it easier for the main generator to pull the generator to be paralleled into synchronization. Therefore, the...

Amidst the current global wave of green economy, industries across the board are actively seeking sustainable development paths, striving to achieve economic growth while protecting the environment. As a vital component of the energy sector, diesel generator sets play an indispensable role in power supply. However, with increasingly stringent environmental regulations and rising energy costs, choosing diesel generating sets that are both economical and durable within the green economy context has become a key focus for many businesses and users. Today, Dingbo Power will provide a comprehensive analysis of diesel generator selection under the green economy from multiple dimensions, including economics and durability.   Economic analysis: Initial investment and operating costs   Initial investment cost: When selecting a diesel generator set, the initial investment cost is a primary consideration. This includes equipment purchase costs, installation fees, and associated taxes...

 In today's electrified era, power generation equipment is widely used. The fluctuation of the load leads to changes in the number of operating generators in the power system. The parallel operation of diesel generators (including grid - connected operation of generators) is a frequent and important operation. The parallel operation of generators has numerous application fields, such as ships, mines, and power plants, and plays a significant supplementary role in the national production and people's lives. As the single - unit capacity of synchronous generators continues to increase, when the two - phase circuits are connected at the moment of paralleling, appropriate paralleling conditions can enable a smooth transition from the original two stable operating states to one stable operating state. Improper operation will generate a harmful inrush current, which may cause electrical damage to the windings of the generator set and even produce a large electromagnetic torque, resu...

 Diesel generator sets can be widely used in various types of enterprises in different industries such as communications, power, petroleum and petrochemical, civil aviation, expressways, ports, ships, national defense, nuclear industry, energy, radio and television, metallurgy, construction, and postal services. It is particularly important for users to have a good understanding of professional knowledge about generator sets. Just as the saying goes, "Know yourself and your enemy, and you can fight a hundred battles with no danger of defeat." Mastering certain professional knowledge about the 700kW Shangchai generator set can help solve problems efficiently and quickly when encountering faults later. Dingbo Power's Generator Knowledge Mini - Course is sharing knowledge about generator set paralleling today, hoping to help everyone solve their problems. What are the conditions for parallel operation of generator sets? The whole process of putting a generator set into par...

In various modern application scenarios, diesel generator sets serve as critical power backup equipment, and their stable operation is essential for maintaining the normal production and daily life. However, diesel generators may encounter various faults during operation. Knowing how to quickly identify and resolve these issues is key to ensuring efficient and reliable performance. Today, Dingbo Power will share some practical maintenance tips to help users better identify and resolve a few common diesel genset faults.   Before discussing maintenance techniques, it is essential to understand the basic structure and working principle of a diesel generator set. A diesel generator set mainly consists of a diesel engine, an alternator, a control system, and auxiliary equipment. The diesel engine generates power by burning diesel, which drives the alternator to rotate, converting mechanical energy into electrical energy. The control system monitors the operational status of ...

With the progress of social development, many devices rely on electricity to operate. A power outage would undoubtedly have a significant impact on numerous enterprises. As a result, the demand for emergency and backup power sources has become increasingly widespread. However, as a complex and large - scale generator equipment, the post - use maintenance of diesel generator sets poses a challenge for many non - professional staff. Therefore, the Generator Knowledge Classroom of Dingbo Power is sharing knowledge about diesel storage tanks and diesel storage today to help everyone use diesel generator sets with ease. 1.Advantages and Disadvantages of Diesel Storage Tanks （1） Iron Storage Tanks Material: Generally made of steel plates about 3mm thick. Advantages: They are not prone to deformation over the long term. Disadvantages: They will rust after about three years of use. （2） Stainless - Steel Storage Tanks Material: Usually made of 304 stainless - steel plates about 1.2mm thi...
