What is a diesel generator set?
2019.11.13
Diesel generator sets are an important part of oilfield drilling equipment and the source of power for electric drilling rigs.
With the improvement of drilling automation and the development of technology, the electric drilling rig power generation system has also made significant progress and changes.
Especially in:The power generation capacity is gradually increasing, and the equipment performance and power supply indicators of the power generation system are greatly improved.Various new technologies are widely used in the control system of diesel generator sets to enable centralized control of the control system.
The rapid voltage regulation and frequency modulation of the diesel generator set improves the static and dynamic performance specifications of the power supply system, and also enhances the system's ability to withstand various sudden loads.
In recent years, in the control of diesel generator sets, new components such as electronic solid-state protection devices and electronic governors have emerged.
Numerical control technology and automation theory have been widely used in diesel generator sets, giving full play to the potential functions of diesel generator sets, making diesel generator sets have higher strength, reliability, stability and good emissions. The operation is simpler and more flexible, and the optimal operation mode of the system is realized, the efficiency of the equipment operation is improved, and the economy and safety of the drilling operation are improved.
The diesel generator set is a kind of internal combustion generator set. It consists of diesel engine, three-phase AC synchronous generator and control system (including automatic detection, control and protection devices).
The mobile diesel generator set consists of a diesel engine, a three-phase AC brushless synchronous generator and a control system. These three parts are all assembled on a common base, while the diesel and generators of the larger power fixed unit are installed. On the common base where steel is welded, the control system of the unit and the fuel tank are usually installed separately from the unit.
The flywheel housing of the diesel engine and the front end cover of the generator are directly connected by the shoulder positioning manner, and the steel column-shaped elastic coupling is used to directly drive the generator to rotate.
This connection is fixed in one piece by screws, which ensures that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within the specified range.
